array_push
Push one or more elements onto the end of array
(PHP 4, PHP 5)
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:
<?php
$array[] = $var;
?>repeated for each var.
Returns the new number of elements in the array.
Example 271. array_push() example
<?php
$stack = array("orange", "banana");
array_push($stack, "apple", "raspberry");
print_r($stack);
?>The above example will output:
Array
(
[0] => orange
[1] => banana
[2] => apple
[3] => raspberry
) ?>
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.
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.
