What are some recommended online resources for PHP documentation?

When working with PHP, it is important to have access to reliable documentation to understand the language's functions, syntax, and best practices. Some recommended online resources for PHP documentation include the official PHP website (www.php.net), which offers comprehensive documentation on all PHP functions, classes, and methods. Additionally, websites like W3Schools (www.w3schools.com/php) and PHP Manual (www.php.net/manual/en) provide tutorials, examples, and explanations for PHP programming.
