Remove everything from the first occurrence of a character to the end of a string in PHP

Question

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

For example,

$print = "50 days,7 hours";

should become

50 days

Answer 1

Here's one way:

$print = preg_replace('/^([^,]*).*$/', '$1', $print);

Another:

list($print) = explode(',', $print);

Or:

$print = explode(',', $print)[0];

Answer 2

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

Answer 3

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];
