Working sample
$tests = array (
foreach($tests as $t) {
  $caseins =  (substr(strtolower($t),0,2) == 'st');
  $casesen = (substr($t,0,2) == 'st');
  if ($casesen) {
    echo "Case Sensitive match on [<b>{$t}</b>]<br/>";
  if ($caseins) {
    echo "Case Insensitive match on [<b>{$t}</b>]<br/>";
  if (!$caseins && !$casesen) {
    echo "[<b>{$t}</b>] does not start with 'st'<br/>";

Open in new window

Case Sensitive match on [street]
Case Insensitive match on [street]
Case Insensitive match on [sTreet]
[treet] does not start with 'st'
[sstreet] does not start with 'st'
Case Insensitive match on [STREET]
[astreet] does not start with 'st'
Case Insensitive match on [Street]
