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

Shortest one:

echo strtok('test?=new', '?');

If you want to keep the question mark, the solution is almost the same:

echo strtok('test?=new', '?').'?';
