Description
int 
array_push ( 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:
     
     repeated for each 
var.
    
     Returns the new number of elements in the array.
    
     
| Example 1. array_push() example | 
<?php$stack = array("orange", "banana");
 array_push($stack, "apple", "raspberry");
 print_r($stack);
 ?>
 | 
 
       This example would result in $stack having
       the following elements:
       | 
Array(
 [0] => orange
 [1] => banana
 [2] => apple
 [3] => raspberry
 )
 |

    Note: 
      If you use array_push() to add one element to the
      array it's better to use $array[] =  because in that
      way there is no overhead of calling a function.
     
Note: 
      array_push() will raise a warning if the first
      argument is not an array. This differs from the
      $var[] behaviour where a new array is created.

     array_shift(), and
