Regex to replace text in REQUEST_URI

[ryel01]

hello!

 

I would like to replace text inside the REQUEST_URI variable for reuse.

 

Basically the REQUEST_URI will contain a key-value pair like...    query=THESUBMITTEDQUERY

 

which could turn up straight after the ?query=THESUBMITTEDQUERY or half way through like ?name=fred&query=THESUBMITTEDQUERY&hello=world

 

So what I want to do is replace the existing "query=THESUBMITTEDQUERY" with query=$variable

 

$url = $_SERVER['REQUEST_URI'];

$url = preg_replace('/??????????/', "query=$variable", $url);

 

Can anyone help me with the right code for ?????????? to do that?

 

Thanks,

 

Regan

"/[\?\&](query\=.*?)[\&$]/i"

 

maybe this?
