Remove everything after a character in PHP

Question

can any tell how to remove characters after ? in php. I have one string test?=new i need to remove the characters as well as = from that string.

Answer 1

Here is one-liner:

$s = strpos($s, '?') !== FALSE ? strtok($s, '?') : $s;

You can test it by the following command-line:

php -r '$s = "123?456"; $s = strpos($s, "?") !== FALSE ? strtok($s, "?") : $s; echo $s;'

Answer 2

Why not:

$pos = strpos($str, '?'); // ? position
$str = substr($str, 0, $pos);
