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; |
Returns the new number of elements in the array.
This example would result in $stack having 4 elements: 1, 2, "+", and 3.
