array_push

(PHP 4, PHP 5)

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");
print_r($stack);

The above example will output:

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
array_unshift().
