Like normal variables, you can pass an array by reference into a function by taking a reference of the original array, and passing the reference to the function. Here is a PHP script on how to pass array as reference:<?php function shrink($array) { array_splice($array,1);}$numbers = array(5, 7, 6, 2, 1, 3, 4, 2);print("Before shrinking: ".join(",",$numbers)."\n");shrink(&$numbers);print("After shrinking: ".join(",",$numbers)."\n");?>This script will print:Before shrinking: 5,7,6,2,1,3,4,2After shrinking: 5Note that call-time pass-by-reference has been deprecated. You need to define arguments as references. See next tip for details. PHP
