To destroy an array? 

First of all, where does $product_id come from?  You gave us no code
that gives us that.

Second, if you're trying to make an array populated with a feild from
each row returned, your first example will work, but not the second. 
The second example will empty the array, and start a new one (which
doesn't make sense to me why you would do that--because in the end,
you're only going to have the array with the last row returned).

But if you're trying to destroy an array doing either:
unset($an_array)
or $an_array = array();
will do the job.

Not exactly sure if this will work, but try

echo eval($string)

Re: [PHP] radio buttons in $_POST

> None 

And if you didn't want it to show to the user (because they have to
make a choice anyway) . . . you can use this css:

input[value="None"]
{
display: none;
}

You should then always have a value to play with in PHP, and the user
doesn't see any extra clutter.

You can use getimagesize to get the size and type of the image as well
as some other information possibly usefull information.

See the directory functions:

See the examples for readdir, which is going to be very similar to
what you're trying to do.

How can I make them have at least 2 decimal places?
So, they will output:

666.75
23.00
269.20
3.234
Thanks in advance!

What I dont understand is that your examples are not consitant.  You 
want 2 or more decimal positions, so as if there are more than 2, to 
leave what exists.  But your first example, you truncate the last 0.  Is 
that a typo, or intentional?

Re: [PHP] Red Hat 9, Apache 2, and PHP

[justin gruenberg]

Jeff Schwartz wrote:

The PHP site (under Servers-Apache 2.0) says "Do not use Apache 2.0 and PHP in a production environment neither on Unix nor on Windows" but isn't clear whether Linux is included or whether it applies to all Apache 2 releases (such as 2.0.46) or just the original 2.0.

And, Red Hat 9 comes with 2.0 so it's really confusing. Has anyone had any experience with this combo?

Thanks,
Jeff
 

When someone says UNIX, they're generally including Linux and BSD, as 
both are UNIX clones.  At this point anyone in their right mind is going 
to suggest you stick with Apache 1.3.x.

[PHP] Re: [PHP-DB] How to get PHP to download web contents

[justin gruenberg]

Steve B. wrote:

How would you get PHP to download a file such as a web page and put it in a string?

What keywords would relate to this (besides php download)

I need a user to be able to put in a name and pass and have PHP go to a cetain site.
The site can take the user/pass in the url so I do not need a form submit.
Then I need the site contents to be in a php variable.
Any tips on parsing html out of it would be great.
Thanks

$fp = fopen("/http://site.com/path/to/file/";, "r");
while (!feof($fp)) {
   $buf .= fread($fp, 1024);
}
fclose($fp);
I like this method more than using file(), just because I have more 
control over what happens.  Since you're reading as its downloading, you 
can do stuff with the data before you're finished. 

As for parsing HTML... regular expressions are very cool.

[PHP] Re: [PHP-DB] Re: XML to MySQL

[justin gruenberg]

I think starting with the XML parsing functions might be a logical step.

For what you're doing, expat  is going to be a 
more logical solution for parsing the xml.  There is also DOMXML, which 
makes more sense to a lot of people, but will be slower at parsing your 
file.

Re: [PHP] Java Applet to PHP Communication

Hello,

I need to be able to communicate from a Java Applet to a PHP program on the

In my web application, a Java Script program will call a Java Applet which
then calls the PHP program on the server. The PHP program works like a
"servlet" and passes the result back to the Java applet which passes the
information back to the JavaScript program.
How can a Java applet work with a PHP program? Are there any special
precautions / programming issues involved?
Thanks in advance

With Regards,

Not anything that you wouldn't have to pay attention to in passing stuff 
between applications in other instances.

I'd use XML/SOAP to pass around the data.  There are many reasons to do 
this, I wont list them here just because there are plenty of articles on 
the web advocating the use of XML.  The added bonus is the buzzword factor.

Re: [PHP] TIP parsing form row data into variables

[justin gruenberg]

Nothing appears blatently wrong in the code you provided, but it's 4am 
here, so I might be off.

This comes to my mind:
1.  $_REQUEST was available from PHP 4.1.0 and later, are you using 
somthing before that?
2.  I assume you're doing somthing with $e_id within your loop, or else 
you're just resetting the contents of it.
3.  You might want to try print_r($_REQUEST) to see if it contains what 
you think it contains.

Hi all,

This might be well known, so apologies if I'm going over old ground - I've
not seen this explained this way.
Last year I did a site using the variable variables method to parse row
data.
Now that I've moved to globals=off, I couldn't get that to work so I tried a
few other options settling for the following:
('howmany' is  the number of form rows on the previous page)

$howmany = $_REQUEST['howmany'];
for ($index = 1; $index < $howmany; $index++){
  $e_id = 'e_id'.$index;
  $e_id = $_REQUEST[$e_id];
Then do something with it.

Hope this helps someone.

Re: [PHP] a question, need an answer

[justin gruenberg]

what is the diffirent between :
//
session_start ();
$_SESSION['eventid'] = 'arma2';
///
and
/
session_start ();
session_register('arama2');
///
Regards
Nabil
 

Both accomplish the same thing, except how you are using it might not be 
what you expect.

$_SESSION['eventid'] = 'arma2'; 
will assign the string "arma2" to $_SESSION['eventid'] (obviously).

session_register('arama2');
will make the variable $arma2 a session variable.  I believe you want 
session_register('eventid')
The session_register way of doing things makes it act a lot like register_globals is on.  It seems like we're trying to move away from this style of coding, so I'd suggest you use the first method with the $_SESSION variable.

Re: [PHP] Embedding image a PHP file

[justin gruenberg]

yy.php should contain

header("Content-type: image/jpeg");  /* or gif or whatever... you can 
also take a look at getimagesize() to get the type of the image 
automatically */
readfile(THE FILE);
?>

it's extremely important that there is no whitespace before the  tag.
