正则表达式从网址中删除某些参数

Hello I have a query which i need to remove from the url

It looks like &h=blablabla (where blablabla can be anything

How do you use regex (or any other method) for the above?

I tried &h=* which is not working

From your question I can't really tell what you are trying to do, but maybe this will help:

$url = "example.org/about-all-of-us&h=blablabla&j=parameter&k=moreparam";

$split_url = explode('&', $url);

print_r($split_url);

Result:

Array
(
    [0] => example.org/about-all-of-us
    [1] => h=blablabla
    [2] => j=parameter
    [3] => k=moreparam
)

Or, if you just need example.org/about-all-of-us, then do this:

$url = "example.org/about-all-of-us&h=blablabla&j=parameter&k=moreparam";

$url = substr($url, 0, strpos($url, '&'));

echo $url; //example.org/about-all-of-us
