Effective way to remove everything after last ? from string

I am trying to strip everything that follows and includes the last ? of a given url. I am currently working with preg_replace but no luck in accomplishing the goal. This is the regex #\/[^?]*$# I am using to single out the last ?. Also is there a faster way by using substr?

Example link:

preg_replace('#\/[^?]*$#', '', $post="www.exapmle.com?26sf213132aasdf1312sdf31")

Desired Output

www.example.com

Add a \? at start of regex instead of \/

\?[^?]*$

  • \? matches a ?

  • [^?]*$ matches anything other than a ? until the end of string anchored by $

Example http://regex101.com/r/sW6jE7/3

$post="www.exapmle.com?26sf213132aasdf1312sdf31";
$res=preg_replace('/\?[^?]*$/', '', $post);
echo $res;

will give an output

www.example.com

EDIT

If you want to remove the entire query string from url then a slight modifiation of regex would do the work

\?.*$

which will remove anything followed by a question mark

Although OP tags regex, Surprisingly nobody suggests explode(), which is much easier.

$post = "www.exapmle.com?26sf213132aasdf1312sdf31";
$tokens = explode('?', $post);
echo $tokens[0]; // www.exapmle.com

Try this its working fine :

$host_url = "www.exapmle.com?26sf213132aasdf1312sdf31";
$part_url = strrpos($host_url, '?');
$result = substr($host_url, 0, $part_url);

echo $result;

Simply match everything from the start upto the ? symbol.

preg_match('/^[^?\n]*/', $post="www.exapmle.com?26sf213132aasdf1312sdf31", $match);
echo $match[0];

Output:

www.exapmle.com

Here's how to do it with substr and strrpos:

$post = "www.exapmle.com?26sf213132aasdf1312sdf31";
$pos = strrpos($post, '?');
$result = substr($post, 0, $pos);
