   (PHP 4 )
   array_pop -- Pop the element off the end of array

Description

   mixed array_pop ( array array)

   array_pop() pops and returns the last value of the array, shortening
   the array by one element. If array is empty (or is not an array), NULL
   will be returned.

     Note: This function will reset() the array pointer after use.

   Example 1. array_pop() example
   <?php
   $stack = array("orange", "banana", "apple", "raspberry");
   $fruit = array_pop($stack);
   print_r($stack);
   ?>

   After this, $stack will have only 3 elements:
   Array
   (
       [0] => orange
       [1] => banana
       [2] => apple
   )

   and raspberry will be assigned to $fruit.

   Warning

   This function may return Boolean FALSE, but may also return a
   non-Boolean value which evaluates to FALSE, such as 0 or "". Please
   read the section on Booleans for more information. Use the ===
   operator for testing the return value of this function.
