PHP Unset Array value effect on other indexes

Question

I am working with a PHP loop, and I had one question regarding how unset affects the array keys. This array uses the standard numeric keys assigned by PHP, 0, 1, 2, 3

Answer 1

This might be a little bit out of context but in unsetting values from a global array, apply the answer by Michael Berkowski above but in use with $GLOBALS instead of the the global value you declared with global $variable_name. So it will be something like:

unset($GLOBALS['variable_name']['array_key']);

Instead of:

global $variable_name; unset($variable_name['array_key']);

NB: This works only if you're using global variables.
