What are the drawbacks of using include() or predefined functions for outsourcing code in PHP?

When using include() or predefined functions for outsourcing code in PHP, one drawback is that it can lead to security vulnerabilities if the included file is not properly sanitized. Additionally, it can make the code harder to maintain and debug if there are dependencies between the included files. To solve this, it is recommended to use namespaces and autoloading to organize and load classes in a more structured and secure manner. 

// Using namespaces and autoloading to organize and load classes

// Define a namespace for your classes
namespace MyApp;

// Autoloading function to load classes dynamically
spl_autoload_register(function ($class) {
    // Convert class name to file path
    $file = __DIR__ . '/' . str_replace('\\', '/', $class) . '.php';
    
    // Check if file exists and load it
    if (file_exists($file)) {
        include $file;
    }
});

// Now you can use your classes without including them manually
$myClass = new MyClass();
