variable variables

by

Firstly, I would use an array for this unless I’m missing something. Having variables like $seat1, $seat2, etc tends to have far less utility and be far more cumbersome than using an array.

That being said, use this syntax:

for ( $counter = 1; $counter <= $aantalZitjesBestellen; $counter ++) {
  $key = 'seat' . $counter;
  $$key = $_POST[$key];
}

Lastly, PHP has an inbuilt function for extracting array keys into the symbol table: extract(). extract() has enormous potential security problems if you use it with unfiltered user input (eg $_POST) so use with caution.
