php array push

array_push ( array &$array [, mixed $... ] ) : int
or
$array[] = $var;

array_push php

// array_push ( array &$array [, mixed $... ] ) : int
// 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 passed value.
// 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.

php array push

If you're going to use array_push() to insert a "$key" => "$value" pair into an array, it can be done using the following:

    $data[$key] = $value;

It is not necessary to use array_push.
