What is the significance of the PHP global variable Array

The PHP global variable $_GLOBALS is an associative array that contains all global variables in a script. This array allows you to access those variables from any scope in your PHP code, enabling better flexibility and functionality, especially in larger applications where global variables are necessary. Understanding how to manipulate this array is crucial for efficient PHP programming.

Example of using the PHP global variable Array

<?php // Define a global variable $name = "John Doe"; // Function to access the global variable function displayGlobalName() { // Accessing global variable using $_GLOBALS echo $_GLOBALS['name']; } displayGlobalName(); // Outputs: John Doe ?>
