Very nice. I was going to suggest:
<?php
$input = "wed-thurs 9:35, 14:56, 18:35, 21, 22, 23:59";
preg_match( "/([a-z]+)-([a-z]+)((?:\s[0-9]+(?::[0-9]+)?,?)*)/", $input,
$output, PREG_SET_ORDER );
$output[3] = preg_replace( "/,/", "", trim($output[3]) );
$times = explode( " ", $output[3] );
?>
But uhhh, your way is much nicer :]
