You are writing a PHP script and you need to access a global variable from within a function. How would you do this using the $GLOBALS superglobal?

  • Use the 'global' keyword followed by the variable name to declare it as global within the function.
  • Access the variable directly using the $GLOBALS array and the variable name as the key.
  • Assign the variable to a local variable inside the function and use it within the function.
  • Create a new instance of the variable within the function and assign it the value of the global variable.
To access a global variable within a function using the $GLOBALS superglobal, you can use the $GLOBALS array and the variable name as the key. The $GLOBALS array is a superglobal that contains all global variables in the global scope. By accessing the variable directly using $GLOBALS['variable_name'], you can retrieve its value within the function. Learn more: https://www.php.net/manual/en/reserved.variables.globals.php
