✍: FYIcenter.com
By default, global variables are not accessible inside a function. However, you can make them accessible by declare them as "global" inside a function. Here is a PHP script on declaring "global" variables:
<?php ?> $intRate = 5.5; function myAccount() { global $intRate; print("Defined inside the function? ". isset($intRate)."\n"); } myAccount(); print("Defined outside the function? ". isset($intRate)."\n"); ?>
This script will print:
Defined inside the function? 1 Defined outside the function? 1
