Re: beginner question about while loops

the while function knows to just go through those and fills in array numbers accordingly?

The while function has nothing to do with it. Using the syntax $array[] simply adds an element onto the _end_ of the array and PHP picks the next logical, numerical index.

OK thanks guys, I got the missing curly brace & some other messes. So when assigning values to an array inside a loop, it knows to advance to the next but then if I want to print those out at the same time, it's complaining while ($file = readdir($fh)){

      if (strstr ($file, '.jpg')){
      $pictures[] = $file;
      #print $pictures[];  #Fatal error: Cannot use [] for reading
      }

var_dump ($pictures[]); #Fatal error: Cannot use [] for reading } This one works but complains about Undefined variable: pictures NULL array (but it dumps the contents of $pictures[]: while ($file = readdir($fh)){

      if (strstr ($file, '.jpg')){
      $pictures[] = $file;
      }

var_dump ($pictures); }
