regex for specific url id

Question

I want to change the id partner=852501 to partner=985412 in my code, but stuck in this step. Example:

http://a-ads.com/?partner=852501

My attempt:

([1-z0-9\/]+)\/\/(a-ads\.com\/?)

How to do the right thing?

Regex: partner=\K[^&]+

Details:

\K resets the starting point of the reported match
[^&]+ Match a single character not present in the list & one and unlimited times

PHP code:

preg_replace('/partner=\K[^&]+/', '985412', $url);

preg_replace you can replace the value

 $string = 'http://a-ads.com/?partner=852501';
 $your = 985412;

 echo preg_replace('/(\d+)/', $your, $string);

UPD: The value can be obtained with the help of preg_match

preg_match('/partner=(\d+)/', $string, $match);

echo $match[1];
