Yes, I wasn't aware that ; could be used instead of :, however you fucked 
up when you said ": is used for constants. ; is used for strings."

Nice to see you're still on form with the fuck-ups.

The syntax may be valid php syntax, but I'll bet any money you like that 
the code doesn't do what you expect under all operating conditions, 
because you have fucked up yet again.

Here is a simple program which demonstrates your fuck-up:

<?php
function test($x){
  echo "testing {$x} for \"fred\", \"jim\" or \"sue\"\n";
  switch($x){
    case "fred"||"jim"||"sue":echo"     match\n";break;
    default;echo"     no match\n";break;
  }
}
$names = array("pete","fred","alan","sue","andy","jim","hank","richard");
foreach($names as $name)test($name);
