Question

What I am trying to do is the following: I have an array of values, these values will eventually be used to generate a random unique string but that’s a little later. First I would like to loop through all the values in the array (foreach loop) then I would like to limit this (while loop) Is this a correct method for doing this?

The below code does not work, can anybody see what I’m doing wrong?

<?php 

    $array = array(
          '1', '2', '3', '4', '5', '6', '7', '8', '9', '0', 
          'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 
          'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 
          'u', 'v', 'w', 'x', 'y', 'z', '!', '£', '$', '%',
          '^', '&', '*', '(', ')', '_', '+', '{', '}'
    );

    $length_of_unique_key = 15;
    $counter = 0;

    foreach($array as $values)
    {
          $counter++;

          while ($counter <= $length_of_unique_key)
          {

          }
    }

?>

Answer 1

Shouldn’t you be incrementing your counter within the while loop, so it can exit?
