array_push
(PHP 4, PHP 5, PHP 7, PHP 8)
array_push — Push one or more elements onto the end of array
Description
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;
?>
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 differed from the
$var[]behaviour where a new array was created, prior to PHP 7.1.0.
Parameters
-
array -
The input array.
-
values -
The values to push onto the end of the
array.
Return Values
Returns the new number of elements in the array.
