multiple cases in switch statement

Hello all... I'm running a little address checker and attempting to catch ordinal numbers (first, second, third, etc) by catching multiple instances such as 1st or 1 gives us FIRST so far I have this... the worst part about it is that part of this is working and the rest is not... when I enter "1" or "1ST" into it, I get FIRST back... when I enter "2ND" or "2" I get nothing back (not even the default no error, no nothin)... when I enter "3RD" I get THIRD back... When I enter "4TH" or "4" I get nothing back (not even the default no error, no nothin)... if ( eregi ( "[0-9]{1,2}([a-zA-Z])*" ,$num ) ) { //echo "hit the switch"; switch ($num) { case ("1ST" || "1"): $street .= "FIRST"; break; case ("2ND" || "2"): $street .= "SECOND"; break; case "3RD": $street .= "THIRD"; break; case ("4TH" || "4"): $street .= "FOURTH"; break; default: $street .= $num; break; } echo $street; Any suggestions on what I'm missing here? What's makes this very weird for me is that the first case WORKS... --------------------- John Asendorf - jasendorf@lcounty.com Web Applications Developer http://www.lcounty.com - NEW FEATURES ADDED DAILY!
