What are some alternative approaches to using the GLOBALS variable in PHP?

Using the GLOBALS variable in PHP can lead to potential security risks and make the code harder to maintain. One alternative approach is to use dependency injection, where you pass variables as parameters to functions or classes instead of relying on global variables. 

// Using dependency injection instead of GLOBALS variable
function myFunction($variable) {
    // do something with $variable
}

// Call the function with the necessary variable
$myVariable = "Hello";
myFunction($myVariable);
