How can a string representing a class name be converted to an actual class name in PHP?

To convert a string representing a class name to an actual class name in PHP, you can use the `class_exists()` function to check if the class exists, and then use the `new` keyword to instantiate an object of that class. 

// Example string representing a class name
$class_name = 'MyClass';

// Check if the class exists
if(class_exists($class_name)){
    // Instantiate an object of the class
    $object = new $class_name();
    // Now $object is an instance of the class represented by $class_name
} else {
    echo 'Class does not exist.';
}
