Question

I have few functions that sanitize everything in get and post but this one must be bit more specific , I have an array that is producing links like

array(
  1 => http://site/something/another/?get_something=1
  2 => http://site/something/another2/?get_something=1
)

also have a function that is sanitizing get and post but that function would clear everything from this array values so I am left with

httpsitesomethinganotherget_something1

can someone please help to match EVERYTHING after get_something=
and clear it or replace it with get_something=1 , something like

$clear = preg_match('/^[A-Za-z0-9]+$/', $array[1]);
preg_replace("/get_something=".$clear."/i","",$array[1]);

You should use parse_url but here is a regex implementation, in case you’re curious:

$urls = array
(
    'http://site/something/another/?get_something=1',
    'http://site/something/another2/?get_something=1',
    'http://site/something/another/?get_something=1&foo=bar',
    'http://site/something/another/?foo=bar&get_something=1',
);

$urls = preg_replace('~[?&]get_something=.*$~i', '', $urls);

print_r($urls);

Should output (demo [updated]):

Array
(
    [0] => http://site/something/another/
    [1] => http://site/something/another2/
    [2] => http://site/something/another/
    [3] => http://site/something/another/?foo=bar
)
