What are some common debugging techniques for resolving issues with PHP classes and file paths?

Issue: One common issue when working with PHP classes and file paths is that the file containing the class definition may not be properly included or located in the correct directory. This can result in a "Class not found" error when trying to instantiate the class. Solution: To resolve this issue, ensure that the file path to the class definition is correct and that the file is included using the require or include statement before trying to instantiate the class.

// Include the file containing the class definition
require_once 'path/to/YourClass.php';

// Instantiate the class
$object = new YourClass();
