array_unshift
    (PHP 4 )
array_unshift -- 
     Prepend one or more elements to the beginning of array
    
Description
int 
array_unshift ( array array, mixed var [, mixed ...])
     array_unshift() prepends passed elements to
     the front of the array. Note that the list
     of elements is prepended as a whole, so that the prepended
     elements stay in the same order.  All numerical array keys will be 
     modified to start counting from zero while literal keys won't be touched. 
    
     Returns the new number of elements in the
     array.
    
     
Example 1. array_unshift() example $queue = array ("orange", "banana");
array_unshift ($queue, "apple", "raspberry"); |  
 
       This would result in $queue having the
       following elements:
        Array
(
    [0] => apple
    [1] => raspberry
    [2] => orange
    [3] => banana
) |   
       |
