Try the array_splice() Function. In the following example, I remove 'black' from the Original Array and the Elements have appered to have been Re-indexed after the splice.

  2. $colors = Array("red", "green", "Blue", "purple", "orange", "black", "magenta", "cyan", "yellow", "violet", "brown");
  3. echo 'Number of Elements in $colors: ' . count($colors);
  5. echo "<BR><BR>";
  7. $colors_removed = array_splice($colors, 5, 1);

pop - Removes from the End of an Array.
shift - Removes from the beginning of an Array.
splice - removes from a specific Array index.
filter - allows you to programatically remove elements from an Array.

Using too many line breaks (<br>) is poor semantic HTML. Better use different logical blocks.

Thanks for the pointer. Brand new at PHP, not my area of expertise (usually live in the Access/VBA Forum).
