In what ways can a PHP developer improve their understanding of class structure and autoload mechanisms to troubleshoot issues like the "Class not found" error mentioned in the forum thread?

Issue: The "Class not found" error occurs when PHP cannot locate the class definition that is being referenced in the code. To troubleshoot this issue, a PHP developer can improve their understanding of class structure and autoload mechanisms. One way to resolve this error is to use an autoloader function that dynamically loads classes when they are needed. Code snippet for autoloading classes: 

spl_autoload_register(function($class) {
    $class = str_replace('\\', '/', $class);
    require_once __DIR__ . "/$class.php";
});

// Example usage:
$obj = new App\ExampleClass();
