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

You could use a regular expression, but if it's always going to be a single pairing with a comma, I'd just do this:

$printArray = explode(",", $print);
$print = $printArray[0];
