How can the global availability of a returned value from a function be ensured in PHP?

To ensure the global availability of a returned value from a function in PHP, you can store the returned value in a global variable that can be accessed from anywhere in the script. This allows the value to be used outside of the function scope.

function myFunction() {
    // Perform some operations
    $result = "Hello World";
    
    // Store the result in a global variable
    global $globalResult;
    $globalResult = $result;
}

// Call the function
myFunction();

// Access the returned value globally
echo $globalResult;
