You may set it... so for example:

Re: [PHP] Re: Search like php.net's URL thingy [0.T]

[Philip Olson]

Hello,

php.net uses a 404 error handler for this, and most mirrors store url data
in an sqlite database. A simple $_SERVER dump in your 404 page will show you
which variables are available.

[PHP] Request for work on the php.net FAQs

[Philip Olson]

Hello everyone,

The PHP manual FAQ has not received much attention over these past  
few years, so it's outdated. This needs to be fixed.


If you would like to add questions (and ideally, with answers) to the  
FAQ then please do so by either adding them to this thread, or point  
them out, and if you would like to work on the manual itself then  
please read the HOWTO: http://doc.php.net/php/dochowto/


Note: Each extension will now have its own FAQ, which means the more  
the merrier. So the URLs will be php.net/{extension}/faq.
Note: Questions and Answers should stand the test of time, e.g., not  
require editing with every PHP version.

Philip

But remember that list() only works with numerical

Because you have two different versions of PHP installed. In
otherwords, the CGI version and most likely the module
version.

Now to answer your question, here's a quote from the 
PHP Manual:

 Note: Prior to PHP 4.3.0, $_FILES information was 
   also included in $_REQUEST.

So, $_FILES is no longer part of $_REQUEST.

Re: [PHP] ODBC Errors and Undefined functions

[Philip Olson]

> Oh and Jay... since no one else has found the answer it would be nice if

Accoding to the source, these two functions require
something to exist:

 #ifdef PHP_ODBC_HAVE_FETCH_HASH
 PHP_FUNCTION(odbc_fetch_array);
 PHP_FUNCTION(odbc_fetch_object);
 #endif

Elsewhere in the source is this:

 #if defined(HAVE_DBMAKER) || defined(PHP_WIN32) ||
 defined(HAVE_IBMDB2) || defined(HAVE_UNIXODBC)
 # define PHP_ODBC_HAVE_FETCH_HASH 1
 #endif

So you need to meet one of the above requirements to have
those two functions available.

According to the changelog, many of these checks were added
in early 2003 (4.3.2) not that this has to do with you but
when documented these should be taken into account. I'll add
this documentation later this week :)

It's difficult to know what you mean exactly but I'll assume
you want to setup FTP access with your text editors as to

dreamweaver does (most text editors do, such as jedit,
ultraedit, editplus, etc.). Here's a tutorial for setting up

Re: [PHP] OT - C programming

[Philip Olson]

For a nice introduction to extension writing, read this
article:

  Part I: Introduction to PHP and Zend
  http://zend.com/php/internals/extension-writing1.php

As well as the various README files found within the php
source files:

  http://cvs.php.net/php-src/

And let's not forget about PECL_Gen. Although it requires
PHP 5 to run, it also allows one to quickly create
extensions that work in both PHP 4/5. There is also ext_skel
but it's slowly being replaced by PECL_Gen:

  http://pecl.php.net/package/PECL_Gen

And of course the Zend API docs:

  http://php.net/manual/en/zend.php

The Zend article above will be a five part series, which is 
pretty cool :)

All PECL extensions are or will be documented at php.net/manual/ but
currently this is not the case, for several reasons, most notably lack
of people to create said documentation. While the current state is
less than ideal, don't think it's how it will continue to be nor how
it's intended to be. And eventually links to this documentation will
exist at pecl.php.net/{extname}, there is an open bug report on this.

No, PECL is not a black hole, but it is a new hole looking to be filled.

And make sure libmysql.dll is available in your systems PATH
and a nice way to do that is adding the PHP dir to your PATH
but a less cool way would be to copy libmysql.dll into the
Windows sytem directory because that directory is in the
PATH.  Don't do that though..

The manual talks about all of this, read the installation
section:

  http://php.net/manual/en/install.windows.manual.php

It says how to set your PATH (via system environmetn variables)
and the MySQL documentation also refers to all of this:

  http://www.php.net/mysql

Both of the above manual pages link to related FAQs so read
those as well.

New installation instructions exist that recommend never copying any
files to the Windows system directory.  It's preferred to leave all files
in the PHP directory and make it (the PHP folder) available to the systems
PATH by editing the appropriate system environment variable.  People copy
files into the Windows system directory because it's in the PATH so no
additional setup is required.  Do not fall into this trap.  Add the PHP
directory to your PATH as doing so will make the world a better place.
The updated manual is as follows:

 http://php.net/manual/en/install.windows.manual.php

If setup this way the above problem would not exist, PHP will find
libmysql.dll.  A FAQ on editing the systems path is here:

 http://php.net/manual/en/faq.installation.php#faq.installation.addtopath

$i  = 1;
$count  = mysql_num_rows($query);
while ($row = mysql_fetch_assoc($query)) {

Yeah, we all know you want magic_quotes_gpc off by default too but can
PHP coders really be that trusted? ;)  I was only referring to MySQL, will
look into the string/int index issue a bit later.  Yes it would be nice if
people validated data but having to write about that everytime gets old.

And quoting integers is not a problem, I even prefer it.  IMHO we should
tell people to quote all values so if someone "forgets" to do any sort of
input validation (i.e. make sure it's actually an integer) there won't be
a major problem otherwise problems (including SQL injection) may arise.

Actually the next step (or perhaps the first step :) would be to read the
following:

  http://www.php.net/mysql

It links to this faq:

  http://www.php.net/manual/en/faq.databases.php#faq.databases.mysql.php5

Which mentions the libmySQL.dll DLL, a very important DLL!  This faq (or a
different/similar one) will soon mention this error and solution, and the
mysql docs will soon make it even clearer.  The Windows extension docs
will also be updated, I am surpised they have not been.

To add further comment.  If you're required to run stripslashes() on
data coming out of your database then you did something wrong.  Your
code would have essentially looked like the following before insertion:

  $var = addslashes(addslashes($var));

Where 'magic_quotes_gpc = on' essentially executed one of those
addslashes().  The above use of get_magic_quotes_gpc() shows you 
how to add slashes just once thus not having a bunch of \' type 
badness inside your database.  Remember backslashes are only 
added to make proper strings for db insertion so the backslashes 
should never actually make it into the database.

One thing to remember is mysql_query() will execute just one (the first)
query so use of ; won't do anything in the above except break the
query.  Still though the point is well taken, be sure to add slashes
(once) and put single quotes around the criteria ($name) and life will be
grand.  Quotes around numerical values won't hurt (such as id = '$id')
although it's not required.  If you choose not to do that then be sure
it's numerical before use (like cast it as an int, or check 
is_numeric(), etc. ...).  Some people check for ';' in the request
variable and if found yell at the user, that can be fun.  bugs.php.net
does this.

In regards to the controversial magic_quotes_gpc PHP directive, I feel it
should remain on by default but if you know what you're doing then set it
yourself.  Scripts that work everywhere should of course work perfectly
with it on or off.  php.ini-dist (the default php.ini) has it on while the
php.ini-recommended has it off.  You must know what you're doing to use
the 'recommended' version of php.ini.  PHP is a newbie friendly language
and newbies are for the most part clueless and don't know what strings or
integers are, or why data should be escaped, or what data validation is or
why it's important.  This is why magical quotes exist as without them
just think how many people would keep getting "malicious SQL" in their
code and blame PHP, or how seemingly random SQL syntax errors would crop
up.  For these reasons dealing with "Why do I get \' everywhere" type
questions is worth it, and why magic_quotes_gpc exists as a php.ini 
directive.

The import_request_variables() function became available 
in PHP 4.1.0 so you have an older version then this (which 
is a bad idea!), consider upgrading.  The manual has version
information, and phpinfo() tells all (including the PHP
version you're using).

Also, your code is *essentially* a runtime version of the much
hated register_globals PHP directive so you have the following
options to mimick the above behavior:

 1) Upgrade PHP! (preferred)
 2) Turn on register_globals in php.ini or .htaccess
 3) Use extract() on various $HTTP_*_VARS variables

Ideally you'd upgrade PHP and use either the superglobals
and/or use import_requests_variables() by using its second 
parameter, something like:

  import_request_variables('gpc', 'r_');

  echo $r_somevariable;

Adding the prefix is a good idea here as you will KNOW these
variables came via the REQUEST as opposed to being 
somewhere from within your script.  Why do you want to
know this?  Read:

  http://www.php.net/manual/en/security.globals.php

So in short you really should upgrade PHP and then use these
request variables as explained here:

  http://www.php.net/manual/en/language.variables.external.php

Yet another solution (just for fun):

$vowels = 'aeiou';
if (false !== strpos($vowels,strtolower($table['field']{0}))) echo 'n';

Strange as the name has not changed and the function
requires nothing special (no IF block around it), here's 
the source:

 http://lxr.php.net/source/php-src/ext/sockets/sockets.c#715

Since socket_set_nonblock() exists you must have
the socket extension available so this is odd.
Are you sure this problem exists and it's not
something silly?  Seems like an impossible problem
assuming your php source wasn't modified :)

Also consider str_replace() as it's faster albeit case
sensitive.  str_ireplace() exists in PHP 5.  Just another
option, I'm surprised you didn't find it when looking
around strpos() and friends.

Your assumptions above are correct, sorry Matt for stepping

This is very much incorrect, not sure where to begin

is a string is a string:

  http://www.php.net/types.string

I'm 99% sure the problem is aFunction() is echoing
a value as opposed to returning one, this is a
common question answered here:

Be sure you rename the "action" part of the "simple html form" 
to whatever page you are using, instead of foo.php, as otherwise 
it will literally attempt to access foo.php  I'm guessing this 
is what's happening by seeing "no input file specified".

Either fix that or on that same manual page is the example 
titled "More complex form variables", this prints to itself
as it demonstrates a use of the popular $_SERVER['PHP_SELF'] 
variable.

Also, it's important you realize the difference between POST
and GET, and how to access them, so you may want to read that
manual page too. (hint: GET is through the URL's QUERY_STRING
(the stuff after the ?) while POST is not).

A few questions:

  a) What's the exact version of PHP?

Maybe I am misreading this question but why not just use id's
instead.  For example, in your database you might have:

  id name  email
  1  john  [EMAIL PROTECTED]
  2  fred  [EMAIL PROTECTED]

In the form you use the names, and unique ids, and the backend
will get the email addresses from the ids.  This way they choose 
names to send to but don't see the email addresses.

There is no Errata per se, but there is a changelog that

that will list every change, such as new parameters,

Re: [PHP] Trouble getting $HTTP_RAW_POST_DATA

[Philip Olson]

Your script should work fine, and to fix claims made in
this thread:

  a) $HTTP_RAW_POST_DATA is NOT an array, it's a string.
  b) It does not live in $_SERVER, or rely on register_globals.

Your code is wrong because you don't provide names for your
fields, so there is no POST data.  Assign your text field
a name, and your submit field a name, and it will work.
Also, keep in mind that $PHP_SELF existing requires the
PHP directive register_globals to be on.

Philip

This is an IIS issue.  The install.txt has specific
information on this topic, have a look.  Also, this comes
up a lot and the following bug report is full of newbies
asking bogus questions but it also contains some good info:

 http://bugs.php.net/bug.php?id=12061

So it looks like security/permission settings where the
php cgi lacks permission.  Also:

 http://php.net/manual/en/faq.installation.php#faq.installation.cgierror

You'll be waiting a long time, until the end of time :)
Because the php4 module is now named php-src, so change
that in the url and you'll be set.

Re: [PHP] imagecreate() error

[Philip Olson]

Hello Michelle-

a) Only enable one GD dll, so use php_gd2.dll.
b) Consider using imagecreatetruecolor() instead but
   either will work.
c) When asking support questions, it's important to
   say exactly what version, although in this case
   we know it's 4.3.0-1 as php_gd.dll was removed in
   PHP 4.3.2

Anyway, enable just one dll and it should work.  Be sure
to restart the web server afterwards.

Philip

I'm glad this feature doesn't exist.  Just think how abused it would 
be, how many people would use it, when few would actually need it.  
Most people can use the data while in the loop, not after.  Or do
what is needed in the sql, not php.  Maybe I'm a little too parental 
though, but so be it. :)

RE: [PHP] $_POST problem

[Philip Olson]

The only time you want to use {braces} like that is
when you are in a string.  None of the suggestions
here are in strings, so the use of {braces} is bogus.
The following is good:

  echo "Hello {$there['friend']} is good";

Note how we're in a string.  This topic is very much
discussed (with loads of examples) here:

  http://www.php.net/types.string

Regarding the question in this thread, it's not clear
what you're problem is.  If the form is method POST,
and you have at least PHP version 4.1.0, there is a
100% chance that the name/value will live in $_POST.

  

  echo $_POST['foo'];

Not sure what the question is, could you be a little
more clear?  It seems you are mixing up img_keywords
and new_keywords, maybe that's it.  Debugging101
would say to check what's in $_POST, which could be:

  print_r($_POST);

Philip

Although really, heredoc can't be compared to either
echo or print, as it's just a string definition that
eventually will be printed.  So I guess you guys are
really comparing "" vs heredoc?  And I agree that any
speed difference (if there is one) isn't a good reason
to choose when readablity may suffer.  So it all
depends on the situation, and the programmer.

I believe this is called "breaking out of PHP mode
and into HTML mode", which can be done anywhere, at
any time.

It works fine, you are using different code then the above.
In your actual code, make sure you pass in an array that
exists, as currently you are not.

One example reason, the foreach is inside a function and
$champs isn't available in the functions scope (global).

At any rate, before your foreach, var_dump($champs) and
it'll let you know what is up.

Regards,
Philip

p.s. In case $row is an array, you actually mean to write
it as $row[$key], but this is unrelated to the error that
foreach is providing.

Re: [PHP] Reading from remote file

[Philip Olson]

This is already fixed in CVS.  The entire example is bogus, 
it should not be using filesize($filename) either.

Here's what's in CVS (the manual will be rebuilt sometime
in the next week):

http://www.example.com/";, "rb");
$contents = "";
do {
$data = fread($handle, 8192);
if (strlen($data) == 0) {
break;
}
$contents .= $data;
} while(true);
fclose ($handle);
?>

And the whole point is to demonstrate the following note:

 "When reading from network streams or pipes, such as those 
  returned when reading remote files or from popen() and 
  proc_open(), reading will stop after a packet is available. 
  This means that you should collect the data together in 
  chunks as shown in the example below."

Have fun :)

Philip

Re: [PHP] Q on echo phpinfo() ;

[Philip Olson]

You may set the location of php.ini by using the PHPRC 
environment variable or during ./configure use the
--with-config-file-path directive.  Maybe you should
just copy a php.ini into the directory PHP is looking for
it in, which appears to be C:\WINNIT.  If PHP was actually
reading a php.ini, you would have instead seen it as
C:\WINNIT\php.ini as opposed to just a directory path.  So
because no php.ini is being read, PHP is using all default
values as per a stock php.ini-dist.

Re: [PHP] PHP5 with MySQL on windows

[Philip Olson]

Hello Janet-

Currently you have two choices:

  a) Compile PHP 5 on Windows yourself, with MySQL support
  b) Wait for a DLL to exist

There isn't a DLL right now, nor do I know when one will
exist.  But, you can be pretty sure that one will 
eventually exist, especially before PHP 5 is officially
released.

PHP 5 beta 1 was released today, there isn't a MySQL DLL
in there either.

In PHP 4, MySQL is of course built in.  That all changed
in PHP 5 where it's no longer built in to the Windows
binaries, nor is it bundled or enabled by default in *nix.

Regards,
Philip

No.  (btw, be sure to quote your strings). In reading 
the table found here:

You will notice short_open_tag has this level:

  PHP_INI_SYSTEM|PHP_INI_PERDIR

And according to the documentation, most namely the
documenation found here:

  http://www.php.net/configuration.changes

It can be set in the following (in Apache) or similar
depending your web server:

  .htaccess
  php.ini
  httpd.conf

Closest you have is .htaccess  But, if you don't want
to worry about it, just use echo as someone already
suggested, instead of embedding it.  Something like:

  echo '';

Btw, the question proposed in this thread is also a
documented FAQ here:

Btw, magic_quotes_gpc and magic_quotes_runtime are totally

Before you touch MySQL or attempt to access it through
PHP, you really should learn basic SQL:

  http://www.sqlcourse.com/
  http://www.w3schools.com/sql/
  http://linux.oreillynet.com/pub/ct/19

Spend some time learning basic SQL syntax and your life
will drastically improve.  Also, perhaps the most popular
tool on this subject is phpmyadmin, it shows the actual
queries as you go which also helps with learning:

  http://www.phpmyadmin.net/

Be sure to keep it secure though as it's a powerful tool.

The above is only true in PHP 4.3.0-1 as there was a

Re: [PHP] mysql_fetch_array(): supplied argument is not a validMySQL result resource

[Philip Olson]

It has to do with you assuming everything will work 100% 
of the time.  It won't.  mysql_query() returns false on 
failure, check for that.  Read this recent thread:

 http://marc.theaimsgroup.com/?l=php-general&m=105517588819420

Also, this faq explains it:

 http://www.php.net/manual/en/faq.databases.php#faq.databases.mysqlresource

Btw, what do you expect: $register_globals; to do in your
code?  It won't do anything useful.

The manual over at phpbuilder is useless, and very old.  Do

Anyway, this extension was removed from the manual 2.5 years

Re: [PHP] Re: Using register_globals

[Philip Olson]

Won't this topic just die? :)

register_globals is not insecure, users are insecure.  Yes, you
can write insecure code with it on or off, and secure code with
it on or off.  By users I mean people who write code, and people
who use it (the evil users are the ones that use the website,
and pass along evil REQUEST data).

In short, read these:

  http://www.php.net/variables.external
  http://www.php.net/security.registerglobals

It should be pretty clear that register_globals = off is preferred
but it's up to you, this is why we have PHP directives.  Turning
of your computer is indeed the ideal security measure!

Do this, to help us and you know your settings:

$info = array('rg'   => ini_get('register_globals'),
  'er'   => ini_get('error_reporting'),
  'de'   => ini_get('display_errors'),
  'id'   => $id,
  'id2'  => $_REQUEST['id'],
  'sub'  => $submit,
  'sub2' => $_REQUEST['submit']);

var_dump($info);

And now, read this entire page:

  http://www.php.net/variables.external

As you are not yet understanding what register_globals is and
btw it has nothing to do with the global keyword.  I am guessing
the above will show register_globals off and the variables you
assume exist do not really exist.  Read that manual page
for why, it should explain all of this to you.

As of 4.3.2, if you compile PHP with --enable-memory-limit

It's one way, not standard imho :)  My additions below are of
course just one way out of many.  In a production environment
you won't be printing out mysql errors, or sql statements, but
instead will give the user some pretty error.  The code below
is for a development environment and doesn't include a "debug"
mode.

The reason I use @ is because we are implementing our own
error handling so having PHP print out the errors too isn't
needed.  So choose one or the other, PHP's errors or your
own, or, turn down error reporting for the entire script
but I'll just use @.

The reason for the error is your are assuming $result is
a valid MySQL result resource when it's not, it's most
likely boolean false because for some reason (like the
connection failed, couldn't select database, invalid
query, etc) it's not valid.  phpnuke is known for having 
crappy code so that's unfortunate for you but anyway the 
words below will explain how to avoid this error, or why 
it may exist.

> [... connection and so on ...]

Making sure the connection and database selection works is
pretty important too:

$conn = @mysql_connect("host", "user", "pass");
if (!$conn) {
echo "Could not connect to MySQL";
exit;
}
if ([EMAIL PROTECTED]('dbname')) {
echo "Could not select database: " . mysql_error();
exit;
}

> $result = mysql_query("select * from ...");
> 
> if(!mysql_error()) {
>echo mysql_error();
> }

Instead of calling mysql_error() twice, it's more common
and efficient to check the return value of mysql_query() 
(in this case we put it in $result) as mysql_query returns
boolean false on failure:

$sql = "SELECT foo, bar FROM sometable";
if (!$result = @mysql_query($sql)) {
echo "Could not run query ($sql): " . mysql_error();
exit;
}

And next, before fetching rows, make sure there are actually
rows to fetch.  Instead of my silly echo statement, consider
including the search form again, or have them press the
back button, or whatever:

if (mysql_num_rows($result) < 1) { 
echo "No results match your query, please try again";

Now it's finally time to fetch some rows as we now know that
$result is a valid mysql resource and rows exist.  This is 
the basic idea of checking if everything worked instead of 
just assuming everything will be perfect 100% of the time 
because it won't.

Re: [PHP] file upload script

[Philip Olson]

What PHP version?  You should rewrite your code to more
reflect what's being used in the manual.

  a) use move_uploaded_file() and not copy()
  b) check what ['error'] has to say
  c) set action in the form
  d) print_r($_FILES) is great for debugging
  e) only show the form is it's not yet submitted,
 or at least print something only if the form
 hasn't yet submitted so you know... debug. As
 for all know, $Submit may never be set.

Philip

Anyone that would suggest using extract() like that would
only do so to quickly make a register_globals dependent
script work (using .htaccess would be preferred there). I
doubt people actually do that for new code, well, at least 
anyone with half a brain.

Re: [PHP] popen() in 4.3.2

[Philip Olson]

PHP 4.3.0-1 has a bug that made your previous code "work",
have a look at the fread() docs for why, here's a quote:

  "Note:  When reading from network streams or pipes, such
   as those returned when reading remote files or from 
   popen() and proc_open(), reading will stop after a packet 
   is available.  This means that you should collect the data 
   together in chunks as shown in the example below."

It goes on to show that you must loop threw it to get
fread() to do what you want in the below code.  Although,
the example it eludes to is wrong (a correct example will
show when the manual next builds), you get the point... :)

Philip

[snip]

In some sense, register_globals = off makes both bad and
good code better, because it means less pollution.   So
many unused variables get defined with register_globals
on and this means wasted memory/resources.  Pollution 
makes any environment worse!  Granted this isn't what you
meant, but still... ;)

After doing a google search for the terms mogrify php:

The first result was this article, it appears to touch
on the subject:
  
  Resizing Images with PHP and Mogrify
  http://www.phpbuilder.com/columns/michael20020712.php3

I'm sure there are many more examples around, and
including PHP in the search field of google is very 
much optional.  But, I guess this all depends on your
knowledge of PHP...  Maybe thumbnail is another good
search term to throw into the mix.

Your new PHP lacks XML support, otherwise this (and all
the other php.net/xml functions) will be defined.  Look
at a call to phpinfo(), you should see something like
--disable-xml in the configure line, or maybe it's 
shared and not included...  Anyway, bottom line is, your
PHP must now lack XML support.

Re: [PHP] file upload script

By no errors, do you mean you have a PHP version greater
than PHP 4.2.0 and checked the ['error'] code, and it
has a value of 0?  Are you sure you want the filename
to be $file_name?  I doubt you do.

What you see in phpweb is what you get, there is no

I've not followed this thread (nor do I want to get involved
with his touchy and difficult topic) but must make a general 
comment on the above code.  One should never mix use of the 
deprecated session_register() function with $_SESSION.  If 
you're going to use $_SESSION, also use it to assign session 
variables.  There is NO need for use of session_register() in 
the above code.

>From the manual (various versions of this text is also in
the manual):

  "If you are using $_SESSION (or $HTTP_SESSION_VARS), do not 
   use session_register(), session_is_registered(), and
   session_unregister()." 

And btw, EXPIRES != expires. 

And lastly, there is now session_regenerate_id() although it
won't set session cookies until PHP 4.3.3.

Philip

It won't make a difference, the issue must be something
