What are the __ construct () and __ destruct () methods in a PHP class?

PHP Training: Understanding the __construct() and __destruct() Methods PHP Training Online Coaching In PHP programming, the __construct() and __destruct() methods play crucial roles within a class. Let's delve into each of them to gain a comprehensive understanding. 1. __construct() Method: The __construct() method serves as a constructor in PHP classes. It is automatically called when an object is created, allowing you to initialize properties or perform any setup tasks necessary for the object. Initialization Tasks: Set default property values. Establish connections to databases or external services. Validate input parameters. Syntax: php class MyClass { function __construct() { // Initialization code here } } Key Points: Only one __construct() method is allowed per class. It is optional but commonly used for object initialization. 2. __destruct() Method: On the other hand, the __destruct() method acts as a destructor in PHP classes. It is automatically called when an object is no longer referenced or when the script execution ends. This method is beneficial for performing cleanup tasks, releasing resources, or finalizing operations. Cleanup Tasks: Close database connections. Release file handles or network resources. Perform final operations before the object is destroyed. Syntax: php class MyClass { function __destruct() { // Cleanup code here } } Key Points: Similar to the __construct() method, only one __destruct() method is allowed per class. It is executed automatically when the script finishes or when the object is explicitly unset. 3.
