Passing Arrays by References to Functions in PHP
How To Pass Arrays By References? in PHP?
✍: FYIcenter.com
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: 5,7,6,2,1,3,4,2 After shrinking: 5
Note that call-time pass-by-reference has been deprecated. You need to define arguments as references. See next tip for details.
