explode with wildcards?

[thefollower]

Hey,

 

Is there a way to explode a string which would have a fixed first half then a wildcard second half... for example say i have:

 

www.domain.com?id=12345678

www.domain.com?id=87654321

 

Notice i got the domain the same but ID is different but say a user inputs it like this:

 

www.domain.com?id=12345678www.domain.com?id=87654321

or

www.domain.com?id=12345678,www.domain.com?id=87654321

or

www.domain.com?id=12345678

www.domain.com?id=87654321

 

Any one of the above inputs could occur from a user

 

But because i know the the id has 8 chars i want to explode it so i can get each link and put them in an array regardless of the format they are inputted.

As far as I'm aware, you can't do this with explode(). However, you might want to look into RegularExpressions, and preg_match_all().

 

<?php
//Untested...
$str = "www.domain.com?id=12345678,www.domain.com?id=87654321";
preg_match_all('~id=([0-9]{8})~is',$str,$m);
echo "<pre>",print_r($m),"</pre>";
?>

 

This would echo out all of the 8 digit strings that appear after an "id=".
