substringing url-variables

[alijsh]

I have the following code:

switch ($c)
{
  default: $source = $index; $header = $h_index; break;
  case "hur": $source = $hur; $header = $h_hur; break;
  case "lista": $source = $lista; $header = $h_lista; break;
  case "deltaXXXX": $source = $delta; $header = $h_delta; break;
}

What i'm trying to do is to neglect the "XXXX" in the deltaXXXX-case. The XXXX are four numbers I want to use to generate the page showing when delta is called.
i've tried caseing it to "delta*", "delta*" and other combinations, bu I can't get it to work.

You can't use a switch statement then, you'll have to use an if-statement and a string function. One way could be:

if (strpos($c, 'delta') == 0) {
// do your stuff
}
