This returns 1 for me on PHP 5.4.32 with PCRE library vers 8.12 2011-01-15

<?php
  echo 'preg_match() returned';
  switch($a = preg_match('/^[a-zA-Z]{2}$/','TZ'))
  {
    case 0: echo '  zero';
    break;

    case 1: echo '  one';
    break;

    case false: echo '  false';
    break;

    default: echo $a ;
    break;
  }
?>
