To add an element to the end of an array, you can of course use the square bracket syntax mentioned previously.
You can use array_push(), which allows you to add multiple elements at once and tells you the new length of the array.
<?php $authors = array("A","B","C","D"); echo array_push($authors,"Hardy","M")."\n"; // Displays"6" print_r($authors);// ww w .ja v a2s .c om ?>
