I have tried that, but it gave me an error telling that $year is undefined.
$year should be a variable but the sort function should loop through all
the years for every code of all the companies, and return the biggest
profit.

That's why I think I need to use a second hash that uses the code of the
companies as a hash key and the profit as its values.

Sorting a hash

[Octavian Rasnita]

Hi all,

I have a hash that have multiple sub hashes and I want to sort it by a sub
key.

For example, I have:

$comp{$code}{$year}{profit}.

And I want to sort the $code values after the value of the "profit" key.

Is this possible directly, or I will need to create another hash for doing
this type of sort?

Thanks.

Using a variable in a perl module

[Octavian Rasnita]

Hi all,

Does anyone know how can I use in a perl module a certain variable defined
in the main program?
I know how to Export a variable from the module to the main program, and in
fact that module uses OOP, but I don't know how to send a variable from the
main program to the module, or how to modify a hash value for a certain key
of a variable from the module.

Is it possible?

Thank you.

Making the program run faster

[Octavian Rasnita]

Hello all,

I have made a program and I have made some benchmarks in order to see how
much time consumes each part of it, and I was pretty surprised when I've
seen that the CGI module takes very much comparing with the other parts of
the program.
Well, I don't need very many methods from the CGI library, but I still want
to use it because many functions are much more simple with it.

Can you recommend me some tricks to make it work a little faster?

If I want to use the OOP style, is it possible to load only some methods and
not all?

Or, if I want speed, is it better to choose the functional style and to
import only a a group of functions?

Why do I need to use multiple CGI objects in the same session? Can you give
me an example?
If I won't find many reasons to keep using the OOP style, I think I will
start using the functional one... (hoping that it will work faster).

Thank you for any suggestions.

DirectoryIndex

[Octavian Rasnita]

Hello all,

I have named index.html a file that in fact is a perl cgi program and I have
put it in the directory /cgi-bin/

It works fine if I access it using an URL like:

http://localhost/cgi-bin/index.html

The problem is that I want to access that program using:

http://localhost/cgi-bin/

But it gives me the 403 Access denied error.

I have put Options FollowSymLinks MultiViews Includes ExecCGI indexes for
that directory but it still doesn't choose automaticly the file index.html
from that directory.

I have tested but it doesn't choose even if I use another extension (like
.cgi) and if I set it to be a DirectoryIndex in httpd.conf.
Do you know if a certain file (like index.html) can be automaticly chosen by
the web server if rezides in a ScriptAlias directory (like /cgi-bin/)?

Or, are there any other secure solutions for what I want to do?

Thank you.

Re: CGI scripts, security and MySQL

[Octavian Rasnita]

This might be helpful for more users, because a system admin can create
automaticly a special dir where the users can put their config files, and
"insert" that file in httpd.conf.
After that, every user can create its own config file, with any variables
they want (their names should not be only "user" and "pass"), and after that
chmod that special dir in order to be viewd only by the root.

Re: CGI scripts, security and MySQL

No, the environment variables are set a single time at the start (or
restart) of the web server.
The problem is that if there is any change in httpd.conf file, the server
must be restarted and this might not be very easy for a system with very
many users, but it is not impossible.

Re: CGI scripts, security and MySQL

[Octavian Rasnita]

Hi,

You can put something like this, in httpd.conf file:

include ...path_to_file

And make the directory where sits that file readable only by the root user.

Then, in that file, put something like:

SetEnv usr user_name
SetEnv pass parolissima

Those 2 environment variables will be seen by any script that runs on that
server.

If you want them to be seen only by the scripts which are ran by a certain
virtualhost, put that  "include" line between  and
.

No, no problem, but it depends how you define that hidden field.
For exemple, don't use as hidden fields autoincreasing numbers but always
use random strings.

Executing a subroutine from a runtime chosen module

[Octavian Rasnita]

Hi all,

Does anyone know how can I do something like:

my $mod = "Module.pm";

#Then require this $mod module (using eval()

#Then executing a certain subroutine from that module and getting the results.

I found that I can require a module and execute it entirely but I am not able to 
choose to execute just a subroutine from it, nor to extract the value of a certain 
variable because if I require that module using eval(), the vars are not exported.

Or is there any other way to do what I want?

(Choosing to run a certain module depending on some conditions, and getting some 
variables from a subroutine which I choose to execute.

Or if you believe that perl can do such a thing, and if you know where on the web I 
could find out more, please let me know.

Thank you very much.

CGI and XML

[Octavian Rasnita]

Hi all,

I have seen that in the last time the XML/XSLT technologies are very much
promoted as beeing the future in the configuration field at least.
I have tried to parse a very small XML file using XML::Simple but I found
that it works very very slow.
It took more than a half of a second just to get and print the data from a
very small file (less 2 kb).
I am wondering how much time it could take if I would need to parse more XML
files, and filter them using XSLT...

I have tried to load the same information from a MySQL database and with the
whole connection overhead it took less than that. I also tried to parse that
information from a .csv file, and it took 10 times less than using an XML
file.
I've seen that XML::Simple uses the expat C library, and I guess that it
might be the core of more XML parsers, and I am almost sure that this
library causes the slowness, so probably all of them have the same problem.
Is there a faster solution for parsing XML files with Perl?
Is there another library than XML::Simple which works faster, or a trick to
make XML::Simple work faster?

Thank you.

Running a Perl module

[Octavian Rasnita]

Hi all

I want to run a certain perl module by getting the name of the perl module
from a scalar variable like:

$module ="Test";
require $module;

I have read in the POD documentation that I need to use:

eval {require $module};
or
eval "require $module";

But the problem is that I cannot get a value returned by that module.

The Test module returns a value named $value.

If I use:

require Test;
print $value;

The var $value is printed without problems, but if I call require for the
$module, the var $value is not exported and I cannot use it.

Is Perl able to run a certain module if getting the name of the module from
a variable, and able to access a value returned by that module?

Thank you very much.

Re: Output Unicode

Yes but I get Google's page with Internet Explorer 6 and I can see that the

But that example page read with IE6 also, is not read correctly.

Re: Output Unicode

[Octavian Rasnita]

Oh thanks, this is helpful.
I can see that it is very complicated to use Unicode standards.

I have seen that on that page I can read the text in romanian language, but
even though I can read well some chars, I am not able to read other special
chars and I can read just question marks instead.

I know that I might need to install some fonts in order to be able to read
them correctly, but it might be a problem with the UTF encoding of that
page, because as I said, I am able to read Google's page without problems.

Re: Output Unicode

[Octavian Rasnita]

Hi,

Thank you for these examples.
I have tried the program, but it printed the following result on Internet
Explorer 6:

Reading and displaying a file with UTF-8 encoded multilingual text.
Japanese string:
?? | |  | ?- |
 | ??

Korean:
?? ??? ?? ? ???. ??? ??? ???

Hebrew
???  ? ?? ??? ??  ??.


It seems that something's wrong because Internet Explorer automaticly
chooses UTF-8 encoding, but it doesn't display the text correctly.
In fact, I don't know which is the problem because I read the text from the
screen using a screen reader (I am blind) but I can read other UTF encoded
pages like Google's page, without problems.

Thank you.

Re: Output Unicode

[Octavian Rasnita]

Thank you.

I have tried to set the header of the web page as you described, but I have
seen that the special chars like şţăîâŞŢĂΠare not recognized correctly,
even though the browser recognizes that the encoding is UTF-8.

However, I have seen that the page returned by Google is viewed correctly,
but their page uses those byte order marks special chars that I don't know
how to print.

If I print only common ASCII chars, I have no problem printing them in UTF8.

Thanks.

Problem installing a module

[Octavian Rasnita]

Hello all,

Does anyone know how can I configure the installation for a perl module if I
want to install it using CPAN library?

I want to install the perl module DBD::mysql and if I try:

perl -MCPAN -e "install DBD::mysql;"

It fails installing the module and it tells me that it can't find mysql or
something like that, but mysql is installed and running fine in:
/usr/local/mysql

Thank you very much for your help.

I have finished making the program to save the files with the .txt
extension, but then I need to change the extension after downloading them,
because if I press enter on a .eml file in Windows, it is opened in an
Outlook Express Window where all the To: From: Date: Subject: fields are
nice arranged and I can read the message easily.

I have also tried to put some garbage in an .eml file to see if this can
fool Internet Explorer, but it doesn't want to work this way either.

I guess that IE recognizes that extension and it is made to ignore those
files... who knows.

File not downloading - off topic

[Octavian Rasnita]

Hi,

Sorry for this off topic subject, but I don't even know where to ask about
this problem.

A program on my site saves some email messages and let me download them
later, and I use the .eml file extension for those files.
When I try to access the URL to one of those messages, Internet Explorer 6
doesn't let me to download it if the files have a .eml extension.
If I choose another extension, (.zip for example), I can download them
without problems.

I've tried that on localhost also, and it happends the same.

For example, I've tried accessing:
http://localhost/z.eml

And the result follows below.

Thank you for any tips why is this happening.

Teddy

Unicode

[Octavian Rasnita]

Hi all,

I have a problem printing a file encoded as UTF8.

I have tried using the following script:

use Unicode::String qw(utf8);

my $text = "astaîâSTAÎÂz";

my $t = utf8($text);

print $t;

The result printed on the screen or in a file is just "az" and not the whole
string.

I would like those non english special chars be converted as UTF8 chars.

Do you know what is the problem?

Thank you.

Re: Special characters

[Octavian Rasnita]

I've tried this method, but unfortunately it doesn't work right.
I have a problems with special chars from other languages.

For example, if I want to type the letter t which in Romanian language is a
"t" with a comma below it, I need to switch to the Romanian keyboard and
press a key which types the code 254.

Well, if I use this code in a character entity like þ in an HTML
document, it shows me a question mark instead (?).

To make it show right I need to use ţ instead.

I don't know why this difference appears nor how I could solve it
automaticly.

So for the moment I need to manually replace each separate special
character.

The CGI pod documentation says that if I use CGI::escapeHTML it will replace
all the characters which are not standard with some named character entities
or if other charset than ISO-8859-1 is used they will be replaced with their
numeric form.
Well, this replacement is not made at all for those strange chars, but only
for < > & " and maybe a few others.

Re: special characters

[Octavian Rasnita]

I found the solution, but I needed to print the chr() for many ansi codes in
order to find the codes I need.

I can see that if I type alt+ a number in order to print its ansi code, it
prints a different char if I choose the keyboard for romanian.
I thought the ansi code is the same but the keyboard keys are mapped to
other chars if I choose another language, but I see that it is not true.

Hi all,

I want to create some web pages that use special characters for foreign
languages (romanian), like staîâSTAÎÂ.

Please tell me what can I do to make them show right in the visitors'
browser.
I've seen that if I just print them, they appear like a question mark

I've seen that other sites can print them right and I don't know how.

Is there an HTTP header I need to set?
Or are there any special Apache settings I need to make?

Fork

[Octavian Rasnita]

Hi all,

Please tell me how could I fork more child processes.
I want to fork let's say 10 child processes.

I know that I can do something like the following, but I am wondering if
there is a clearer method:

if (my $pid = fork) {
#parent

if(my $pid2 = fork) {
#parent 2

if (my $pid3 = fork) {
#parent3
}
elsif(defined $pid3) {
#child3
}
}
elsif(defined $pid2) {
#child2
}
}
elsif(defined $pid) {
#child1
}

But this method is very confusing if I want to fork more child processes,
and I want to let the user choose how many processes wants.

Thank you.

Re: hit counter

[Octavian Rasnita]

I don't know, but this is not the right way.

You need to open each image in perl with open(), read the content of the
file, then print each content one after another.

Re: hit counter

[Octavian Rasnita]

Open each image file and print their content one after another and they will
be printed right.
Don't forget to use the right HTTP header for printing an image (image/gif).
And don't forget to open the files using binmode if you are under Windows.

But your program will be totally useless for the blind visitors that won't
be able to read that image on the screen.
A better idea would be to use server side includes and print a text hit
counter, or use Javascript to include the text generated by a CGI script if
your server doesn't accept SSI.

Determining different computers with the same IP

[Octavian Rasnita]

Hi all,

I heard that it is possible to differentiate 2 computers of 2 different web
page visitors that have the same IP address.

I know that each computer is sending some information in %ENV variable, but
is there any other method to differentiate them?
The information from %ENV can be changed so I cannot rely on it.

Thank you very much!

How to fork a process?

[Octavian Rasnita]

Hi all,

I've tried the following code:

#!/perl/bin/perl -w

use strict;

$| = 1;

print "Content-type: text/html\n\n";

my $pid=fork;

if ($pid) {
print "parent\n";
exit 0;
}
else {
⊂
}

sub sub {
sleep(100);
open(OUT, ">>f:/teddy/.txt") or die "Can't write to .txt - $!";
print OUT "test";
close OUT;
}


This script should fork the child process which after waiting 100 seconds it
should print a test text in a file.
The problem is that if I run the script from a web browser it waits for 100
seconds before it finishes.

If I add:

close STDOUT; close STDIN; close STDERR;

...The script ends immediately, but the child process is not executed at
all.

I am trying to make it work under Windows and Linux.

Help!

I've discovered that I can make what I want if I create 3 scripts.
1. Just exec the second perl script with exec("perl script2.pl");

2. Forks a child process and in the child process exec() the third perl
script.
3. Just does what I want (the time consuming script).

Is there a method to do this without needing 3 scripts?
I would like to do it with only  1 ...or 2.


Thank you.

Re: Finding the current path

[Octavian Rasnita]

Thank you, but $0 will tell me the path and the file name of the script.pl
file, not the path from where I ran the script.

If the current path is:
/var/www
(This path is shown by pwd command).

and the script is in:
/home/script.pl

if I run:
perl /home/script.pl

if the script will print $0, it will print:
/home/script.pl

But I want it to print:
/var/www
(Meaning the current directory).

Now, I could run pwd and get what I want, but in fact I need to run this
program under Windows.

Thanks.

Does anyone know if it is possible to find out the path in which a perl

For example, I am in /var/www and I run the following command:

Re: Capturing At Compile Time

[Octavian Rasnita]

Are you sure it is a binary file?
But anyway, a perl program can be made to be an executable that doesn't need
perl to run it.
Download Active State Perl Developer Kit from www.activestate.com for this.
The file is not compiled, but the perl interpreter is included in the
executable file with the perl program, and the other libraries.

There is a program named perlcc that should compile a perl program, but it
doesn't work.

Re: [Addendum] Stripping HTML from a text file.

[Octavian Rasnita]

It doesn't work because you check for the beginning and the end  tags
in the same line, but you have splitted the text in more lines, and the
 can be found in a line but the  tag on another line probably.


You can use something like this:

$html =~ s|]*>.*?]*>||si;

So you don't need to check each line separately.

It works for the  head tag but it doesn't work for all the tags, because you
might have a page like this:


a1
a2
a3
b1


...


b3


If you will want to delete everything from  until its corresponding
 it is more complicated because if you will use that simple regular
expression it will delete until the first  but not until the second
one.

Getting the partial content from a cgi sccript

[Octavian Rasnita]

Hi all,

A few days ago I was asking what makes a server allow returning a partial
content (when using the Range HTTP header).

There were some discussions that the core of the server might decide that,
that some modules of the server (mod_cgi and mod_php...) decide that, or
that the CGI program can be created in such a way so its content can be
returned partially.

I've tested a little using a cgi program made in perl and a php program that
print a few characters, and their content needed to be returned partially.
I've made then a cgi program in perl that should get the partial content of
those files.

Well, using Apache 2.0.4 under Windows let me download both files partially
with the specified ranges, without doing anything special in the server
settings nor in the cgi script. I just used the Range HTTP header.

Probably it doesn't depend on the server modules, or probably my server
modules supports this, or the web server core is responsable for that.

However, I don't think that there is a setting somewhere where we can choose
if we want the server return partial content in order to allow resuming
downloads.

Re: automated file removal / cache clearing

[Octavian Rasnita]

But why forking more processes?

The cgi program might check which of the files need to be deleted, then
create a temporary lock file, then it could fork a process that will delete
those files.
The next visitor will come and execute the same cgi script, but it will see
the lock file and it won't delete any file.

In fact, if the web site has many visitors, the script could be put on a
script which is not so often executed by all visitors.
Or that script could check and start deleting files only after a period of
time, let's say... 10 minutes, 1 hour... etc.

at first blush that CAN seem to be an interesting
idea - but in the worst case one can have N connections,
each of which has generated N forked children to
walk through M possible files... and one starts
asking one's self,

is this an order N square or N factorial solution?

while in the worst case the cron job based solution
is merely an order N problem...

You can use fork to avoid putting the visitors to wait until the program is

Re: Counter triggered on download

[Octavian Rasnita]

This is a pretty good method, but it is not so good because the visitors
won't be able to use a Download manager to download the file.
Or better said, they won't be able to resume the download.

I am not sure, I will be testing this soon, but maybe a solution for this
problem could be specifying the Content-length of this file as a HTTP
header.

This way the browsers and the download managers will be able to send the
"Range" HTTP header and the web server will accept it.

But as I said, I am not sure yet.

Put the link to a cgi script which makes an HTTP forward using the

Re: disable back button

[Octavian Rasnita]

You cannot disable the back button and the keyboard hotkey for this task
from a perl script.
You might need to use a client side program, like a Javascript one.

However, you can make a page not to cache, and to expire immidiately, and
this way if a visitor will press the back button the page won't be shown
automaticly.
However, they will be asked if they want to resend the data to the server
and if the visitors will answer 'yes', the browser will resend it with no
problem.
You need to use this method, and also check on the server that the data was
not submitted for a second time.

To print the http headers for not allowing caching and to set the expiration
date to immidiately expire, use something like:

print <
...

Re: perl script as binary

No, you don't need to add any dll files (at least with ActiveState Perl

The perl interpreter is included in the .exe file by default. If you want

needs to be  used.

Re: Why executable?

[Octavian Rasnita]

Oh, but I guess this is a little security improvement, not?
But now... another related question.

If the shebang line is not needed by the web server (if I will define an
action to run perl in httpd.conf), is the shebang line used for something
else?

I've tried chmodding the perl script to 755, and I've tried running it with:

$ script.pl

...but it didn't want to run, telling me that there is no command script.pl,
even though the script has a shebang line in it.

Oh, do you know if I can specify the action for running .pl files and .cgi
files with perl in a .htaccess file?

Thanks.

This is what I do for security on my webserver.  I don't have the
shebang line in my scripts.  The webserver has a list of approved perl

web server executes it with perl.  Otherwise, it treats the file as if

Hmm, are you telling that I can create a perl file and name it file.html,
file.php, or even file.asp, and use a shebang line in it, then it will be
parsed as a perl file?
Or I need to use extensions that are not set in the server's conf file to be

And if you are required to include that "extension" as part of your

You should never be able to guess the implementation language by

Why executable?

Hi all,

Does anyone know why the perl scripts need to have the execute permission
under Unix?

I am asking this because I've seen that the PHP files don't need this
permission.

Couldn't perl just read a text file (doesn't matter if it has an execute
permission or not), interpret it and execute it just like PHP does with its
programs?

Re: Perl line breaks

[Octavian Rasnita]

It depends how is set the web server to execute the programs that will
process the CGI scripts.
By default Apache is set to need the shebang line and it doesn't use the
registry settings, but this can be changed.

...and you don't need to print the HTML header in the BEGIN {} block.
You can just print it at the top of the perl program or in the middle of the
program but before anything else is printed.

I think in Windows, -w isn't enough. The #!perl line is ignored in most

Therefore, you should do this explicately.

Also, with some webservers doing the following as your first line in the

Re: Perl line breaks

[Octavian Rasnita]

What web server is installed on that computer?
Some web servers need to use non parsed header scripts (NPH) and I heard
that this is the case with MS IIS if this is the web server.

The line break is not very important for perl scripts under Windows. I use
only the Unix end of line (lf) under Windows for my perl scripts and they
work fine.
I don't know if they would be working the same if I will be using Mac end of
lines, but with Unix end of line they work fine.

I guess you should send that script to the list...

At the very least these are the right questions to be asking. It really
depends on your situation if you are developing an application that is
intimately tied to sending email then it is a good thing that you know
how to call sendmail, and its intricacies. More important than that is
probably how to build an RFC compliant mail message. If this is your
situation then maybe a module is not right, however if your situation is
doing computationally intensive queries on a bio/genetic database, then
who cares how the message goes out that contains the output as long as
it gets where it is going, in this case the algorithms for generating
the content are far more important and time is better spent on them.

That is the other beautiful thing about Perl modules (at least the ones
on CPAN) they are open source so you can see how they work if you have
the time.

When we recently re-architected our app the first step I took was
looking into mail sending modules, logging modules, and cryptography
modules. I installed all of the variants I could find, became at least
proficient with each so that I could accomplish the smallest task that
mimiced my end goal and constructed a list of pros and cons for each. In
the case of cryptography (gnupg/pgp) the modules that were available
ranged from mediocre to very good, but none fit the specific
requirements of *my* project, so I built my own, but for mail I found
that there were at least two that provided all of the functionality (and
much much more) I needed and so I used one of them.

In general I have found that there is a middle area where a module is
least likely to fulfill my need, and by this I mean in complexity. The
more or less complex a task then usually a module can be found that
accomplishes the goal, it is the middle ground where a module may not be
robust enough to accomplish the task or may have different requirements
than mine that usually one can't be found that is just right. For the
very complex (like mail) assuming a module exists at all, usually it is
better than what I could accomplish in the span of time alotted so I
will choose to use it.  Most often for simple tasks a module doesn't
have to do much and may even be among the standard module base, for
instance copying a file across filesystem boundaries. A relatively easy
task that could be coded over and over, but with the File::Copy module
so accessible why bother

Just some thoughts...

Re: Perl line breaks

This code is working fine under Windows, but maybe you have made some
mistakes in your subroutine that  prints the header...

You don't need to print so many separate lines using the print "...";
function.

You can use:

print <

Here is the part of the perl script that I start printing things to the

my $header = 'Successful update';
my $msg = "Your preferences have been updated

&HTML_ender;

Note that I have also tried using print qq| ... | code as well.

Re: Preserve line endings via ftp

[Octavian Rasnita]

If you set the transfer method to binary, the file is sent as it is, without
changing anything.
If you set it to ascii, the end of line character is set to lf for
Unix/Linux, crlf for Windows, and cr for Mac.

If your FTP program or the FTP library you use is not doing this correctly,
this means that it could have a bug because  it might not recognize well the
operating system and put the correct end of line.

But transfer the files in binary mode, then change the end of line to be
the correct end of line character for your system... if it is not possible
otherwise.

Setting the transfer type to binary didn't work.

Reading perldoc Net::FTP did:

ASCII is the default
type, and indicates that the sender of files will
translate the ends of lines to a standard representation
which the receiver will then translate back into their
local representation.

So I kept the unix line endings on the file and ftp'd to the Novell
server and the DOS line endings appeared over there.

For the record, this worked with both 'binary' and 'ascii' translations.

Re: How to display multiple web pages depending on

[Octavian Rasnita]

If this is a problem, you can use always $show = 50; ... for example.
This way you will let the visitors choose only the number of records that
should be skipped.

But I don't think that this is a problem because either way you do your
page, the visitor can create a program using the LWP library and get your
pages one by one, then combine them, parse them and steal all the data from
them.

This works well depending on the case. If the fact that you have a lot
of data is valuable in itself, or if your server is subject to heavy
loads, DOS attacks, etc. then you may not want to provide the method to
determine the number to select as an argument as anyone could choose an
arbitrarily high number to get all of the data then just use a parser to
"steal" your data, or if you have lots of data to overload your db with
multiple selects of all of the data, etc.

Just something to keep in mind otherwise I like this approach and use
something very similar,

Re: How to display multiple web pages depending on

[Octavian Rasnita]

It is not very hard.

You can use an sql statement like this:

my $sth = $dbh->prepare("select id, name, age, bla from table order by name
limit ?, ?");
$sth->execute($skip, $show);

You can get the number of rows you want to skip ($skip) and the number of
rows you want to show ($show) using the CGI package like:

USE  CGI;
my $q = new CGI;
my $skip = $q->param('skip');
my $show = $q->param('show');

You can check first the total number of rows that could be displayed, then
you can compare, and if the total number of rows is bigger than the $skip +
$show, meaning the latest record printed in the current page, then you can
print a "Next" link, and ... do the same with the "previous" link

The idea is you create a ranged loop.

for (x..x+y) {
  #blah
}

#blah is where you put all your code for retrieving lines from the SQL dbase
and HTMLize them and return them.

x is obtained through CGI params

my $q = new CGI;
my $start = $q->param('start');

x+y is obtained however

1-
my $end = $start + $q->param('amount_per_page');
2-
my $end = $start + 50;

whichever.

Then;

for ($start..$end) {
#grab from db, htmllize, append to scalar variable...
}


print <

$scalar_from_for_loop


EOF

and, yeah...

Should put you on the right track.  I wrote my own customized interface to
SQL
(actually its an interface to the normal DBI interface, heh..) so I didn't
write that portion since what I use would not at all be like what you would
use.

Re: PHP vs Perl

[Octavian Rasnita]

Of course I will remain subscribed and I am not gonna start learning PHP
immediately.
I am thinking to learn it because in my country there are only 2 books for
learning perl in my native language and even though I don't need them, there
are very few perl programmers and almost no jobs for perl developers.
There are even some programmers that just heard about perl but they don't
even know too well what it is, and they are good programmers in their
languages.

My problem is that I am used to work under Windows where no compiler is
installed by default and where some CPAN modules don't even compile under
this OS, and I cannot just jump and use Linux because Linux is not an
operating system too accessible for the blind, and I am totally blind.
Unfortunately I cannot try to solve this problem and start creating an
accessible version of Linux then creating perl programs under this OS.

Perl is great because OF CPAN also, but there are very many modules that
require Linux, some of them don't even tell this but the modules don't even
want to compile under this OS.

I am not trying to convince somebody that PHP or Java is better than perl,
but I am just trying to see what makes those programming languages so... "en
vogue".

For example a programmer in Java can create not only java servlets or java
server pages, but they can also create java applets and desktop programs
with a graphical interface while this is not possible with perl.
Internet Explorer, the most used browser can display java applets, but it
doesn't support perl scripts and those perl scripts cannot create a
graphical interface in the browser.
perl can create descktop programs with a graphical interface using the Tk
modules, but those modules are not accessible at all for the blind. They use
some strange classes that print the form like a picture on the screen while
Java programs can be made accessible with Java Access Bridge.

Well, see, these are perl problems, but perl doesn't have a company like Sun
Microsystems to fight to solve them, and it doesn't have so many advertisers
either.
For example, after installing Apache under Windows, by default PHP is set to
be accepted after instalation, but perl is not set and we need to add the
"AddHandler" lines in the httpd.conf file in order to make it work.

It is very clear that Apache is promoting PHP and there are not very many
companies that promote perl.
I've started to find (very strange) web hosting providers in my country that
offer PHP support and space for free and some of them unlimited traffic, but
they don't offer perl support at all.

I am not sure that PHP is used more than perl now, but after 5 years... it
will be used more than perl for sure.

Which could be the solutions?
- To have some Tk classes that are accessible for people with dissabilities.
- To be able to have the programs compiled as binaries (.exe under Windows)
without needing to embed the perl interpreter in the code like with perlapp,
or to have a kind of runtime environment - the perl interpreter installed
separately, but without any other unneeded modules.
- to have a very good development environment for programmers (I don't need
it, but new programmers in this language is searching for such a thing) and
it doesn't exist.
(I've tried comodo of ActiveState, but it is not accessible for the blind
like other programming languages environments)
- To have precompiled modules for Windows and for other operating systems
for much more packages than ActiveState has now.
- To have a set of kind of standard modules for creating, editing and
reading more file types that are precompiled and which can be installed
easier and a set of modules for working on the web, comunicating with more
merchant accounts,  shopping carts...
- to promote packages that contain perl, Apache, MySQL and possibly other
tools for programmers, because most programmers that test their programs
locally need them.

Re: PHP vs Perl

[Octavian Rasnita]

Of course you're almost right, but exactly this is a problem. A language
which I need to fight a lot with in order to find the right syntax for doing
something is not a very clear and easy to use programming language.
I like more the perl way than needing to learn very many functions names,
like when working with PHP or Visual Basic, but I like that PHP can be
installed as a package with the most used libraries, I also like that there
are some prebuild packages that contain Apache, MySQL and PHP configured in
such a way that they all work very nice.
There is no such a thing for Perl.
It is not very easy to install support for SSL, or the library  for creating
images for perl, while for PHP is much easier.

I think there are a couple of myths that need to be cleared up from that
post.

First, the idea that PDF manipulation and secure payment modules "don't work
very well" in Perl. If one has had difficulty in making the modules work for
them, it does not necessarily mean that the module is at fault - in some
cases it might be, but typically I've found that when a module isn't working
for me, I've usually missed something.

Second, the idea that most of the new work can be found in PHP and ASP is
not necessarily the case. The tech industry has taken a hit over the past
few years, and if you're looking at the job boards like Monster, maybe most
of what you *see* is slanted toward Microsoft technology. PHP and ASP are
pushed at corporations because somebody at a high level in the chain has
been told these are the widgets they should use. Trust me, I worked for one
of the major telecom players for 6 years, and I've seen how the buzzwords
work themselves into the hiring process.

However, in my business (I deal with small to medium-sized companies),
they're not concerned about what technology I use as long as it works. So
far, the language that makes most of my projects work is Perl.

I think the reason why PHP is used more and more much than Perl is that for
CGI related programs it is much simpler to use than perl.
For example it has a set of libraries for the most used functions in a CGI
program, for example SSL support, a module for reading and creating PDF
files, modules for accessing some payments operators for shopping carts,
etc.
Those modules can be created in perl, but even if some of those modules
exists for perl, they don't work  very well. I've tried to use the modules
for creating a PDF document under Windows, but with no success.
It is pretty hard to install some of the perl modules under Windows because
most of them need to be compiled, need a compiler to be installed, etc.

With PHP it is much simpler to work and I can see this even though I don't
know PHP at all yet.

The motivation for new perl learners is not very big because most of the
jobs can be found in PHP/ASP and only after that in perl/Cold Fusion.

I hope Perl 6 will have much more standard modules and the modules from CPAN
will be able to be installed without compiling them with a local compiler.
We should keep in mind that even if the most web servers are running under
Unix/Linux, most computer users and possibly web developers are working
under Windows and the CPAN modules should be all compatible with Windows
also,  and not only with Linux.

I was thinking the same thing when I read that. Swap the first occurence of

It says, 

Re: PHP vs Perl

[Octavian Rasnita]

This is the reason I've began to learn perl and not PHP, but for CGI
programs I found that PHP might be easier.
I know that PHP is much more limited even for CGI programs than perl, but
for simple tasks it is much better.
And... most CGI programs are not extremly complicated.

I don't mess around with php, but I do follow the discussions of it's
merits vs. perl on http://perlmonks.org.

I've been able to synthesize this from all the discussions:

PHP will give you the same performance benefits as using mod-perl.

PHP's drawback is that you are learning a language that can only be
used for web programming.

So well written mod-perl is comparable to PHP. I think the allure of PHP
is that it is probably easier for a beginner to learn, but it is a
dead-end, because you can't use it outside of web programming.
And as most perl programmers know, web programming is only a tiny
part of the usefulness of perl.sysadmin scripts, text processing,
task automation,etc.

Re: PHP vs Perl

I don't say that mine is bigger than yours because perl is the only
programming language I know and I found out that I also need to know a
little C if I want to compile some perl modules that give a lot of errors.
I don't know PHP at all, but I found out that I could create the same thing
with PHP without needing me to know other programming languages.

In fact I also want to know why PHP is used more than Perl and this is
obviously.
I see less and less CGI files ending with .cgi or with .pl or /cgi-bin/
directories in the path of the URLS, but more and more I can see .php and
.jsp.

If we say that perl don't have any problem it will be used less and less
without having any problem.
I think that we should point out which are its problems because maybe they
can be solved.

This is the same kind of canned response that is the reason why this is
a flame war topic and was met with such jest immediately after being
asked.

1) Still not possible to prove that PHP is used more than Perl, which
also makes it impossible to prove it isn't

2) All of the modules you stated exist for PHP, exist for Perl, many of
them probably before those for PHP were developed. CPAN is the envy of
all languages, ask a Java developer familar with Perl sometime about how
they feel about CPAN...

3) What modules have you used that didn't work very well?  Ignorance
with respect to a module's interface does not prove poor performance.
Most modules that I have encountered have all worked as they claimed and
solved the goals' that they were designed for.

4) ActiveState has a very good list of modules available in a binary
format and that list is growing continuously, and most modules (at least
those that would be used on the web) are available from ActiveState, or
either without a compiler (though make is needed) or will compile under
windows with the proper free utilities. Laziness with regards to
installing modules doesn't indicate they don't or won't work.

5) From my time spent in the job market I would say it is pretty well
divided among all of the languages, especially since most postings read
something like "6 years of experience in Perl, CGI, ASP, PHP, Oracle,
COBOL"  (love that last one) which is a very poor indicator of the
actual market...

6) I feel sorry for the development house (and their clients) that
develops their site on a different system than it will be served (and I
don't mean a developer sitting at a Windoze machine ssh'd into the
server since that can't count because in that case they don't need the
modules locally).  Which means that if they are serving on Windows they
know what is available and are more likely able to get something to work
(I mean they are developers they ought to have a compiler available on
their own platform and know how to use it).  On Linux/*nix of course
this is mostly moot... (and there is 60+% of us on that platform)...

7) Let's not even mention coldfusion...

Now we were having a very nice (albeit weird) discussion about MVC and
pixies, let's not turn this into the typical mine is bigger than your's
discussion
