How do you use the $GLOBALS superglobal in PHP?
- By accessing specific variables using their names as keys in the $GLOBALS array.
- By assigning values directly to the $GLOBALS variable.
- By calling the global() function followed by the variable name.
- By declaring variables with the global keyword.
The correct option is 1. To use the $GLOBALS superglobal in PHP, you can access specific variables by using their names as keys in the $GLOBALS array. For example, to access a global variable named "myVariable", you would use $GLOBALS['myVariable']. This allows you to retrieve the value of the global variable or modify it directly through the $GLOBALS array. It provides a convenient way to access global variables from anywhere within the script without having to use the global keyword. However, it is generally recommended to use global variables sparingly and consider alternative approaches, such as passing variables as parameters or using dependency injection, to achieve better code maintainability and testability.
