You are writing a PHP function and you need to use a variable that was declared outside of the function. How would you access this variable within the function?

To access a variable declared outside of a function within the function's scope, you can use the global keyword followed by the variable name inside the function. This allows you to access and modify the value of the variable. However, it is generally recommended to pass the variable as a parameter to the function to promote better code organization and avoid potential issues with global variables.
