How can I replace the value of a GET var in the URL

[cooldude832]

I'm trying to create a search result page.  with the url that has someone.com/serach.php?critera1=sometihg&critera2=something&limit=0

Limit is what sets which part of the matching results it will display. This script works great if I manually set limit by using my mouse in the url and changing it to 1,2,3,4,5,etc etc, but I want to change it dynamically so that I can say:

 

previous 1 2 3 4 5 6 7 8 9 10 next

 

and those be links to pages where Limit is equal to what ever number they are.  Is there a simple way to change limit with out having to explode the url string apart chopping it down to just limit=n or limit=nn and then chop limit=n/limit=nn at the = and implode the whole url back together?

Your question confuses me a little bit. Can you provide a more detailed explanation?

that is my url, but i think I got a simple solution

i'm going to try this

$urlexplode = explode('&limit=',$url);
$limit = $urlexplode[1];
$url = $urlexplode[0];

 

as long as someone don't mess with my url.

all of those variables, and their values, are available in the $_GET superglobal array.

Take a look at the function http_build_query(). I think it will help you solve your problem.
