List of PHP Supported Time Zones

In the version of PHP that we're running, there are 423 supported time zones. That's a bunch. Here's a list of all those time zones along with human readable displays, dumped into an array for easy copying and pasting:

(If you're using this to populate an HTML dropdown, scroll down, I have that code pre-constructed for you below this array.)

And, in case you need different formatting, here's the code I used to build that list:

$timezones = array();
$zoneskeys = timezone_identifiers_list();
foreach ($zoneskeys as $key) {
	$key = str_replace('_',' ',$key);
	$p = explode('/',$key);
	if (count($p) == 1) { $zone = $p['0']; }
	elseif (count($p) == 2) { $zone = $p['1'].' - '.$p['0']; }
	elseif (count($p) == 3) { $zone = $p['2'].', '.$p['1'].' - '.$p['0']; }
	else { $zone = '??'; } //this shouldn't ever happen
	$timezones[$key] = $zone;
}

If you're using this data to make an HTML dropdown list, this might save you some time:
