[SOLVED] Formatting a URL string

[Canman2005]

Hi all

 

I have a value defined like

 

$url = $_SERVER['HTTP_REFERER'];

print $url;

 

Which produces a url with a

 

did number which can be something like 55

 

and a

 

tid number which can be something like 3

 

a full example is

 

http://www.myweb.com/files/page.php?did=55&tid=3

 

I want to get php to format whatever is outputted and then remove everything before the did number and everything after it.

 

With the above, it would remove the first part

 

http://www.myweb.com/files/page.php?did=

 

and then the second part

 

&tid=3

 

and leave me with just

 

55

 

Can this be done? Its hard to explain what I mean but someone may understand me

 

Thanks in advance

Try this:

 

<?php
$pattern = '/[^t=][0-9]+/';
preg_match($pattern, $url, $matches);
echo $matches[0]; //55
?>

If you have numbers in the file name or website or you have more variables in the url, you will need to add to $pattern variable. I'm sure someone could make a more bullet proof expression, but for your example, it should work.

Assuming that we're talking about grabbing the URL parameters from the currently loaded page, here's a simple method that avoids regular expressions altogether:

 

$args=$_GET;
echo $args['did'];
