The simple form if($var) seems to work fine and I see it in code often.
Is there a good reason for using isset?

Yes, if you don't use isset(), you may see notices (errors) if the 
variable is not set. This depends upon the error reporting settings of 
the server. However, if you use isset() you won't see notices regardless.

Steve!!!
This is great!
I had no idea you could use arrays in url variables.  That makes everything 
much easier.

Thanks very much

Strictly speaking, your original question referred to what PHP calls 
'variable variables':

http://us3.php.net/manual/en/language.variables.variable.php
However, most of what you can do with them can be done more simply with 
arrays. In your example above, use

myPage.php?dataPoint[]=10&dataPoint[]=20&dataPoint[]=30
and you get an array
$dataPoint[0]=10
$dataPoint[1]=20
$dataPoint[2]=30
The number of data points is count($dataPoint). See
http://us3.php.net/manual/en/language.variables.external.php
for more info on this technique.

I'd also suggest to add the index in the dataPoints, so you're not
relying on the browser or php to determain what order the array
will be built.

myPage.php?dataPoint[1]=10&dataPoint[3]=20&dataPoint[1]=30

Re: [PHP] Newbie Question: Variables on the fly

[PHP4web]

ok let say that you have 2 or more variables with same name but there are
difference in numbering And Values like this :

$var1 = 1 ;
$var2 =  12 ;
// etc ..

now you must now how much of number of this varibles before you deal with it
or you must store it on array to know how to count it in the fly like this :

$var[var1] = 1;
$var[var2] = 12;
// etc ..
$var_count  = count($var); // give you the count

now you can deal with vars like this :

$i = 1;
do {
$NewVar["NewVar".$i] = $var["var".$i] * $WhatEver ;
$i++;
}
while ($i <= $var_count );

And finally you can extract vars by extract() to make them in normal shape
if you get my point

If I have multiple instances that match the pattern, but only want the 
first one, which is the best way to handle it?

Putting the "U" flag seems to work, but I don't understand the full 
implications of using it here. 

preg_match("|$start(.*?)$end |Ui", $contents, $text);
Alternatively, I could use preg_match_all and use $text [1].

Looks like you have some extra spaces in there that'll mess it up. The '?'

could it be that this is an old script that requires register_globals to be

Unfortunately, strtotime() can't convert mysql timestamps of the form 
MMDDhhmmss (the default 14 character timestamp).  Here's a 
function to do it for you:

function convert_timestamp ($timestamp, $adjust="") {
   $timestring = substr($timestamp,0,8)." ".
 substr($timestamp,8,2).":".
 substr($timestamp,10,2).":".
 substr($timestamp,12,2);
   return strtotime($timestring." $adjust");
}

Remember that the $adjust string needs to be properly spaced- "+ 30 
days", not "+30days"!

RE: [PHP] Newbie question

[Sam Masiello]

It appears as if you don't have MySQL support compiled in with your PHP
build.  If you installed it from source you will want to recompile PHP
with the --with-mysql option.  I have never installed PHP from RPM
though so if you installed it that way, perhaps someone else in the
group can provide some guidance on how to do that.

HTH!

Post your code (if it's from a book I'm guessing it isn't very long),
will be able to pinpoint cause of the error then.

That's not entirely accurate.

---Quoted from http://php.net/header ---
Remember that header() must be called before any actual output is sent, 
either by normal HTML tags, blank lines in a file, or from PHP. It is a 
very common error to read code with include(), or require(), functions, 
or another file access function, and have spaces or empty lines that 
are output before header() is called. The same problem exists when 
using a single PHP/HTML file.


header() doesn't need to be 'the first line of the page', but it does 
need to be placed above/before any output gets sent to the browser.

if there's any code following the redirect (which you don't want to

I agree that is the way it should be, but my client is looking for a quick
fix, not a good one.  In the end it is fortunate for my client that the
quick fix is not a viable one.  I agree that all variables should be scoped,
it is the right way to do things.  I think I have my query question figured
out.

A client moved their site from a server (unknown details) to a
hosting
facility (php 4.3.2).  Now none of the scripts work.  I have guessed
that
they are coming from an earlier version of apache/php.
[/snip]

It is likely then that register_globals is set to OFF in the php.ini. In
earlier versions this directive was set to ON. It was a "security issue"
that was more about bad coding than a PHP vulnerability. If you passed a
form field with the name of userName it could be accessed by PHP in the
$userName variable, with RG off you would have to access it via
$_GET['userName'] or $_POST['userName'] dependent upon the processing
method of the form.

[snip]
Also, how bad is the _REQUEST scope I read that "it could not be
trusted"
[/snip]

Again, bad coding would present a danger here.

PS. How do you scope queries?

I am not sure what you are asking here. Do you mean making a query
public or private?

You're thinking about this in the wrong way, it seems. The server 
probably has register_globals Off, where previously he was programming 
with it being On. or vise-versa. They should be Off, and should be left 
off, but programming with them off needs some adjusting. Variables such

Hi Al

Sessions and objects are quite easy to use in the latest version of PHP, and
would be my personal recommendation. I have a coupleof test scripts that I
regularly

contact me offlist and I will mail these to you and you can try it out for
yourself.

I think you'd have to send the value via $_GET or save it in a session
variable if you want to retrieve it on another page.

The optional specifiers to the left of the decimal place have a psuedo
last-to-first precedence.  For example:

$price = .65;

printf("'%8.2f'\n", $price);
-> '   0.65'

This shows that there are 8 characters reserved for the number to the
left of the decimal.  Therefore, '8' is the width specifier.

printf("'%-8.2f'\n", $price);
-> '0.65   '

printf("'%08.2f'\n", $price);
-> '.65'

printf("'%0-8.2f'\n", $price);
-> '0.65000'

Re: [PHP] newbie question

[Wang Feng]

 "1. An optional padding specifier that says what character will be used for
padding the results to the right string size. This may be a space character
or a 0 (zero character). The default is to pad with spaces. An alternate
padding character can be specified by prefixing it with a single quote (').
See the examples below."
"3. An optional number, a width specifier that says how many characters
(minimum) this conversion should result in."
 http://au.php.net/manual/en/function.sprintf.php



Assume that $price=.65; then the "%0.2f" yields 0.65.

If we follow what the manual says, then can you tell me what the 0 is used
for? Is it a (optional) paddinng spcifier OR is it a (optional) width
specifier OR both? And why does it yiled 0.65 rather than .65?


(The manual doesn't explain things clear, man.)

I believe the documentation (in at least on of the ?printf() functions
describes how the implementation follows the C specs. I'm pretty sure
the ?printf() family of functions were added almost entirely for the

I think, without any help, the only way to make it clear is to read the
source code of that function in php. The manual doesn't explain the function

But I'm sure many people here knows the answer well. Come on. Where are you?

I say, "I dunno".  :-)  It seems to follow C's printf(3) conversion
specification.  If a decimal point is needed for a float, it must also
have a digit in front of the decimal point.  This is kind of annoying if
I want to print decimal-only values without preceding zeroes.  Maybe

Specifies the minimum character width of the conversion.  See PHP's

Hi, Eugene,

If I get rid of the 0 and tried this:

It displays "0.65" in my Mozilla browser correctly. What do you say then?

Hi,

I 'm in the process of modify one of my sites to use PHP/mysql instead of
ASP/Ms Access.

The Access database has 200 records in it.

I have PWS, mysql and PHP running on my local PC.

I have used Navicat from mysqlstudio.com to import the access database into
mysql and then exported the data back out as an sql script.
The script consists of multiple sql statements like :

INSERT INTO mydatabase
  (id, Description, Department, RetailPrice, PrefSupPartNo, PrefSupplier)
VALUES
  (1, "Bunting Plastic Union Jack 4m", "Flags & Bunting", "2.5", "JFB",
"Smiths");

Is there a way of "including" the sql script file into a PHP page or do I
have to copy and paste the statements into a PHP page with a "mysql_query"
statement after each sql statement, to load these records to my ISP's remote
server.

p.s My ISP has no GUI interface into mysql so all manipulation is done via

On the same note I recommend phpMyAdmin(www.phpmyadmin.net). Its interface
is quite useful especially when you have multiple DB's to manage on the same
server.

You can download PHPMySQL and locate it in a secure portion of your site.
It's an excellent gui interface into mySQL.  This tool will allow you to
upload the script file and insert the data.  I'm sorry, but I don't know the
URL where to get it.  Check sourceforge.

Hi,

I 'm in the process of modify one of my sites to use PHP/mysql instead of
ASP/Ms Access.

The Access database has 200 records in it.

I have PWS, mysql and PHP running on my local PC.

I have used Navicat from mysqlstudio.com to import the access database into
mysql and then exported the data back out as an sql script.
The script consists of multiple sql statements like :

INSERT INTO mydatabase
  (id, Description, Department, RetailPrice, PrefSupPartNo, PrefSupplier)
VALUES
  (1, "Bunting Plastic Union Jack 4m", "Flags & Bunting", "2.5", "JFB",
"Smiths");

Is there a way of "including" the sql script file into a PHP page or do I
have to copy and paste the statements into a PHP page with a "mysql_query"
statement after each sql statement, to load these records to my ISP's remote
server.

p.s My ISP has no GUI interface into mysql so all manipulation is done via
PHP.

Thanks very much for any guidence.

Phil.

You should make sure to quote your html values ( href="value" ), it

I miss typed what I need to do.

$row_rep_RS['repEmail'] is actually the email address I want to turn into a

So I guess it would look something like.

RE: [PHP] Newbie Question regarding Syntax

[Cesar Aracena]

I would encourage you to use double quotes instead of single quotes
inside the PHP code. After this, you must comment HTML double quotes so
the PHP engine does not consider these as part of its code. I would type
your example like this:

mailto:[EMAIL PROTECTED]">".$row_rep_RS['repEmail']."";

?>

Note how the only concatenated string (using periods) is the variable
$row_rep_RS[] and the double quotes inside the HTML link were commented
using a backslash.

HTH,

RE: [PHP] newbie question

[Jay Blanchard]

[snip]
I just setup php on my linux box and have been messing with a tutorial, 
and have had some issues.

The tutorial says any name=value pairs in the querystring "automatically

creates a variable with the name and value the querystring indicated". 
This does not seem to be happening.

I have installed:
RedHat 9.0
Mysql 4.0.13
PHP 4.3.2
[/snip]

It is because the tutorial is pre PHP 4.x where register_globals = off
in php.ini. Your form variables will be in either $_GET['variablename']
or $_POST['variablename'], or you can turn register_globals 'on'

HTH!

RE: [PHP] Newbie Question

[Cal Evans]

you have 2 functions named DBField.  This was ok until 4.3. After 4.3 you
couldn't re-declare a function like this.

PHP does not allow for overloading like Java and C++ (It looks like that's
what you are trying to do)

Check the docs for overloading.  There is some support for it but it's a bit
of a kludge. (IMHO, etc.)

Try this:

It's untested - shout if it doesn't work.

Re: [PHP] newbie question

[Scott Houseman]

This is very simple

To access variables from GET form, which you would use request.querystring( ) for in 
ASP,
use the $_GET array in PHP, e.g. $var = $_GET{'var'}
To access POST form values, which you would use request.form( ) for in ASP, use the 
$_POST
array in PHP e.g. $var = $_POST{'var'}.

Cheers!

RE: [PHP] newbie question

[M.A.Bond]

It depends on the version of PHP, in older versions you just use the
variable name ie in your example just use $var to access it's contents. In
new versions, with register globals turned off use $_GET['var'] to access it
ie:

Print $_GET['var']

Will print numberx

Without a better explanation of what you mean by "go to the proper web page" 
the best answer that can be given is:

Re: [PHP] Newbie question about UNIX command-line directives

[Rasmus Lerdorf]

As mentioned a couple of times on that include page, you can just use
ini_set() directly in your application to set include_path.

eg.




That will run through each directory listed in your include path.  That
is, it will check for:

 ./foo.inc
 ../foo.inc
 ../../foo.inc
 /usr/local/lib/php/foo.inc

in that order.

I wasn't clear before.  The problem I'm having, and most of the others 
folks who commented, with include is really with "include_path".

A good bit of the problem seems to be my virtual host's environment. 
Most things I've tried with directives in an htaccess don't work and the

What does include have to do with DirectoryIndex?  And what exactly is
your problem with include?  The only trick is setting the include_path
which doesn't seem all that obtuse to me.

Re: [PHP] Newbie question about UNIX command-line directives

[Al]

The problem may be due to the fact that my environment is Apache Unix.

I spent about two hours today pouring over the php on-line manual 
"include" spec and trying dozens of combinations. 
http://www.php.net/manual/en/function.include.php

There must be at least 20 user contributed notes at the bottom.

It is incredible that such a basic php function should be so obtuse and 
ill defined.

I'm going to give your other suggestion a try tomorrow.

Thanks again

I wondered about the DirectoryIndex directive's ability to utilize files 
in other directories, so did a little test, which is what you indicated 
you tried in your initial email:

   DirectoryIndex ../index.htm

Worked fine.  Apache 1.3.26.  Windows NT.

So, your problem could be a web server configuration thing, as Rasmus

Beyond the things already discussed, I'm at a loss.

Does your AllowOverride include "Indexes"?  If it doesn't, you can't put
DirectoryIndex in a .htaccess.

httpd -L is your friend.

Re: [PHP] Newbie question about UNIX command-line directives

[Al]

Appreciate the feedback, but.

The .htaccess approach appears to fit my situation best; but, I've not 
been able to get it to work.

I have a folder with a php script and that folder has several 
sub-folders each with a small configuration script.  I'd like the entry 
point to be a subfolder and main script [in the parent folder] to be 
"symbolically" executed.

I'm familiar with the DirectorIndex and use it often, but only for 
defining the default file for the particular folder.

Could I be doing something wrong? Or is there another htaccess directive 
  that may work?

Thanks.

In a PHP script, you can do this -- if permissions are favorable:

   exec('ln -s ../afile.php index.php');


> Is there some way to do this [e.g., with a htaccess file]?

In an .htaccess file, you can put this

DirectoryIndex afile.php

It makes a link in the file system.  -s makes the link symbolic.

Two options.  Put the output in between  tags.  Or if you want the 
regular font, in PHP use the nl2br() function.

Exactly- I could see uses in PHP, but they're so limited that it's

The only reason a compiled language would not include a
function/module/etc
is to reduce the size of the final executable.

Since php doesn't store (barring the caching engines, but they work
differently anyway) a compiled version, it doesn't need to worry about
not
including something.

Yeah, that's what I figured.  With C++ you could find evidence that it

PHP loads everything up before it starts doing anything. It's only going
to execute the code it needs to, though, of course. I asked this
question a while ago and got that answer. The process of loading all of
the code is minimal, though, compared the actually executing the code.

Nope.  Everything is brought into memory at compile time.  Or at least 
that's the way I understood it to be.  I suspect it's still the case.

PHP loads everything up before it starts doing anything. It's only going
to execute the code it needs to, though, of course. I asked this
question a while ago and got that answer. The process of loading all of
the code is minimal, though, compared the actually executing the code.

RE: [PHP] Newbie Question on Efficiency : Follow-up Question

[Michael Kennedy]

OK, if I understand C++ correctly, if I write a program and #include
 or something similar and compile the program it only
compiles with the used functions in it, right?  So, if I never use 'cin'
it leaves that function out of the final complied app.  

Does/can PHP do anything similar?  I'm always much more comfortable with
a language when I can understand how it works and I'm sure some of you
feel the same.

Now, I fully understand that PHP documents are not even close to being
compiled in the traditional sense.  But, I'm wondering if it pulls all
the necessary functions into memory when the page is accessed, then uses
them when needed, or does it pull the whole include()d file into memory
and just combine the whole mess together into one big memory heap and
run like that?

My gut tells me that it's the second one, but I'm just wanting to be

life, but I'm just curious...  Also, I hope the above question isn't

If you have have a large number of functions, it might be better to
separate
them into a few files that you can include as needed. I use one file
that
contains functions needed by every page. I have a few other files that
contain functions that aren't needed by every page, so, I include them
only
on pages that need them. But most functions go in the main include file
used
on every page.

Separating them will also minimize some overhead if you have a lot of
functions. Otherwise, if your include files aren't War & Peace in
length,
one include file is fine.

Re: [PHP] Newbie Question on Efficiency

If you have have a large number of functions, it might be better to separate
them into a few files that you can include as needed. I use one file that
contains functions needed by every page. I have a few other files that
contain functions that aren't needed by every page, so, I include them only
on pages that need them. But most functions go in the main include file used
on every page.

Separating them will also minimize some overhead if you have a lot of

one include file is fine.

He may also consider the position of the inc/decrementor.
Example (note that the first element of an array has index 0):

$a = Array(1,2,3,4,5);
$i = 1;

executing

echo $a[++$i]
will output
3 2

echo $a[$i++]
will output
2 2

In both cases $i gets incremented, but the value used to access the 
array might be before or after the increment takes place, according to 
the incrementor (or decrementor, if you use --) position. A subtle, but

Arrays in PHP are very useful and easy to use. I had no problem. And I
have no book about PHP :). I use manual, because it's the best book. I
looked through some books and find that the PHP manual is MUCH better.

r> Last question:

It's called sleep() :)
Once again, use manual. Espacially if you work on Windows. Then just
download the manual in CHM.It includes index and search capabilities.

You should be ashamed of yourself... www.php.net/sleep :)

As for arrays, they are invaluable and not that hard to understand.
Don't skip over them, read the chapter a couple times if you have to...

Re: [PHP] Newbie question to everybody....PHP

[Rasmus Lerdorf]

I have never really understood why people have problems with arrays.  Just
think of an array as a table of values.  A one-dimensional array would be
a table with a single column and each row has a number (or index)
assigned to it:

  +---++
  | 0 | Apple  |
  +---++
  | 1 | Orange |
  +---++
  | 2 | Banana |
  +---++

In PHP this simple array could br created like this:

  $fruits[0] = 'Apple';
  $fruits[1] = 'Orange';
  $fruits[2] = 'Banana';

Or there is a shortcut:

  $fruits = array('Apple','Orange','Banana');

Now, the row numbers (or indices) do not have to start at 0.

  $fruits[7] = 'Apple';
  $fruits[10] = 'Orange';
  $fruits['foo'] = 'Banana';

Would create a table like this:

  +-++
  | 7   | Apple  |
  +-++
  | 10  | Orange |
  +-++
  | foo | Banana |
  +-++

As you can see, row names don't even have to be numbers.  When using
non-numerical array indices like this the array is sometimes referred to
as an associative array, although in PHP we don't really differentiate.

The shortcut for creating this array where you name each row would be:

  $fruits = array(7=>'Apple', 10=>'Orange', 'foo'=>'Banana');

and obviously, to display an element you would do:

  echo $fruits['foo'];

To loop through and display every value in the array you can use foreach:

  foreach($fruits as $value) echo $value;

If you also want to display the row name (also known as the index or the
key):

  foreach($fruits as $key=>$value) echo "$key: $value";

Now, what really seems to confuse people are multi-dimensional arrays, but
they are exactly the same.  A multi-dimensional array can be thought of as
a table with more columns and you give each column a name as well now.
Just like a tic-tac-toe board:

  01
  +---++---+
  | 0 | Apple  | 1.99  |
  +---++---+
  | 1 | Orange | 2.99  |
  +---++---+
  | 2 | Banana | 0.89  |
  +---++---+

So the Apple element would be in position 0,0, Orange would be 1,0 and
0.89 would be in position 2,1.  Or in PHP you would write this as:

  $fruits[0][0] = 'Apple';
  $fruits[0][1] = 1.99;
  $fruits[1][0] = 'Orange';
  $fruits[1][1] = 2.99;
  $fruits[2][0] = 'Banana';
  $fruits[2][1] = 0.89;

That's of course a bit wordy.  If you think of this slightly differently,
consider that each row is actually a small array of two items.  The fruit
and the price.  So you could also write this as:

  $fruits[0] = array('Apple',1.99);
  $fruits[1] = array('Orange',2.99);
  $fruits[2] = array('Banana',0.89);

And then further breaking it down, we see that $fruits is just an array of
arrays, so it could actually be written as:

  $fruits = array(array('Apple',1.99), array('Orange',2.99), array('Banana',0.89));

and again, you don't have to use simple numbers to name your rows and
columns.

 NamePrice
  +---++---+
  | a | Apple  | 1.99  |
  +---++---+
  | b | Orange | 2.99  |
  +---++---+
  | c | Banana | 0.89  |
  +---++---+

  $fruits = array( 'a'=>array('Name'=>'Apple', 'Price'=>1.99),
   'b'=>array('Name'=>'Orange','Price'=>2.99),
   'c'=>array('Name'=>'Banana','Price'=>0.89) );

Looping through a multi-dimensional array is a little trickier:

 foreach($fruits as $k=>$arr) {
echo "$k: ";
foreach($arr as $kk=>$val) {
   echo "$kk: $val ";
}
echo "\n";
 }

If you run that code on the $fruits array you will get this output:

a: Name: Apple Price: 1.99
b: Name: Orange Price: 2.99
c: Name: Banana Price: 0.89

So basically you loop through all the rows and then inside each row
iteration you loop through each column.

This is about as complex as you are ever likely to get.  You may end up
with 3-dimensional or higher arrays, but there really is no difference.
The display loop will of course get more complex as you will need another
level of looping.  For a 3-dimensional array you would have items like
$fruits[0][0][0] and your display loop would be:

  foreach() {
foreach() {
  foreach() { }
}
  }

1. I have dug deeper into arrays than I care to remember.

2. Absolutely not.

3. See http://www.php.net/sleep and http://www.php.net/usleep

Glad to hear you're converting to PHP! It's an amazing language, and I
don't see it going away any time in the near future. Hope you have fun,
and be sure to ask if you have any more questions. I always try and
answer questions on the list if I have the time, and know the answer.

Greetings people,
Special greetings to all of you who have helped me in the past.

As most of you know i am a newbie, I learned a bit of PHP via webmonkey
and
a few other places, seeing the power of PHP i decided to convert from
Java
servlets and JSP (JSP coz its expensive to host and not many hosting
opportunities) so I baught a book called "The PHP black book".
Anyway, now that the background is done heres my questions:

1)How many of you have seriously dug into arrays and has it been
important
in your programming?
1.1)Do you think you could have done the same thing you did with arrays
WITHOUT arrays?
(The reason i ask this is theres a whole chapter dedicated to arrays in
the
book & its pretty frustrating)
Last question:
Is ther any function to make the program "sleep" for 10 seconds or so?
or
does anybody have a function that does this?

ANY replies good,bad,flames will be welcome.
Cheers,
-Ryan.

Hi!

1. I believe every serious programmer out there uses arrays on a regular 
basis...
1.1. ...exactly because there are so many problems virtually unsolvable 
without them. Take for instance the case of a product page where people 
would fill in ordering quantitites.

My recommendation would be not to study arrays, but rather try solving 
problems using them - that way you'll have a better chance to remember 
what you've learned. But then again, that's me - maybe you learn better 
in other ways.

If you want to sleep, you can use sleep($seconds). But why in God's name 
would you want to do that?

Why would you want a scripting language to sleep, there is no such thing as
a loop in a web page (yes, I know it would be possible, but it would lock up
a users machine).

I know you can set up the apache daemon to run on-demand to conserver
resources, but I think you are getting mixed up between compiled and
interpreted (aka scripting) languages.
