(PHP 4 )
array_push -- Push one or more elements onto the end of array
( array array, mixed var [, mixed ...])
array_push() treats array as a stack, and pushes the passed variables onto the end of array. The length of array increases by the number of variables pushed. Has the same effect as:
$array = $var;
repeated for each var
Returns the new number of elements in the array.
Example 1. array_push() example
$stack = array("orange", "banana");
array_push($stack, "apple", "raspberry");
This example would result in $stack having the following elements:
 => orange
 => banana
 => apple
 => raspberry
