What role does autoloading play in avoiding errors related to class definitions in PHP?

Autoloading in PHP helps avoid errors related to class definitions by automatically loading the necessary class files when they are needed, instead of having to manually include them in every file. This ensures that all classes are available when they are called, reducing the chances of errors due to missing or incorrect class definitions.

// Autoloading classes in PHP
spl_autoload_register(function($class) {
    include $class . '.php';
});

// Example usage
$obj = new MyClass();
