remove everything after first comma from string in php

Question

I want to remove everything(including the comma) from the first comma of a string in php eg.

$print=\"50 days,7 hours\";

should become \"50

Answer 1

This should work for you:

$r = (strstr($print, ',') ? substr($print, 0, strpos($print, ',')) : $print);
# $r contains everything before the comma, and the entire string if no comma is present
