    str_replace

    The & symbol stops str_replace from working.

    Eg:
    This won't work..
    $matches = str_replace("0-0&compID=","IT WORKS", $matches);

    But these will:
    $matches = str_replace("compID=","IT WORKS", $matches);
    or
    $matches = str_replace("0-0","IT WORKS", $matches);

    How can I get the first example to work?

    Works for me.
    What version of PHP are you using and what is the string in $matches?

    Yes it will. I've run your code on codepad and it works fine. It may be something to do with your php OR your cross contaminating code / files etc (done that plenty of times myself )

    Here is a link to your code being run on codepad:

    Handy tip for you, always test suspect code on another php enabled machine (such as codepad) to see if the problem can be replicated

    You can use preg_replace

    Code:
    <?php
    $text="http://www.sportingpulse.com/rpt_fixture.cgi?id=17343238&client=0-2307-128783-0-0&compID=223607&a=FIXTURE";
    
    $text=preg_replace('/0\-0\&compID\=/i','IT WORKS',$text);
    
    echo $text;
    ?>

    Preg is only useful if there is a reason to pattern match instead of directly replace. If you know the literal string to find and replace, then pattern matching is a waste of resource.

    For the OP, can you check to ensure that your string doesn't use &amp;? You'll need to check the source for the output as HTML will render the &amp; as &.

    Legend Fou-Lu.
    I should have checked the source, instead relying on the browser. I can't believe I missed that. Thanks
