What is the $GLOBALS superglobal in PHP?
- An array containing references to all variables that are currently defined in the global scope of the script.
- A variable that stores global values for a PHP script.
- A special function for accessing global variables.
- A reserved keyword for declaring global variables.
The correct option is 1. The $GLOBALS superglobal in PHP is an associative array that contains references to all variables that are currently defined in the global scope of the script. The keys of the $GLOBALS array are the variable names, and the values are references to the corresponding variables. It provides a way to access global variables from anywhere within the script, including within functions or classes, without having to use the global keyword. By accessing the $GLOBALS superglobal, you can retrieve and manipulate global variables as needed. However, it is generally recommended to use global variables sparingly and follow good coding practices to avoid potential issues.
