php-laravelHow do I use a global variable in Laravel with PHP?

A global variable in Laravel with PHP can be used in the following way:

1. Declare the variable outside of any functions and classes. For example:

$globalVar = "This is a global variable!";

2. Use the global keyword in the function or class where you want to use the variable. For example:

function myFunction() {
    global $globalVar;
    echo $globalVar;
}

myFunction();
// Output: This is a global variable!

3. Use the $GLOBALS array to access the global variable from within a function or class. For example:

function myFunction() {
    echo $GLOBALS['globalVar'];
}

myFunction();
// Output: This is a global variable!

4. Use the $_SERVER array to access the global variable from within a function or class. For example:

function myFunction() {
    echo $_SERVER['globalVar'];
}

myFunction();
// Output: This is a global variable!

In Laravel, you can also access global variables from within views. For example, you can access the $globalVar variable in a view like this:

{{ $globalVar }}
