What are the potential consequences of not including necessary code, such as "array_push," in a PHP function?

If necessary code, such as "array_push," is not included in a PHP function where it is needed, the function may not work as intended and could result in errors or unexpected behavior. To solve this issue, ensure that all necessary functions and methods are included in the PHP code to properly manipulate arrays. 

<?php

function addToArray($array, $element) {
    array_push($array, $element);
    return $array;
}

$array = [1, 2, 3];
$newArray = addToArray($array, 4);
print_r($newArray);

?>
