In what scenarios would using global variables be considered acceptable in PHP programming?

Using global variables in PHP programming can be acceptable in scenarios where you need to access a variable across multiple functions or files without passing it as a parameter each time. However, it is important to use global variables sparingly as they can make code harder to maintain and debug. 

// Example of using a global variable in PHP
$globalVar = "I am a global variable.";

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

printGlobalVar(); // Output: I am a global variable.
