You also get explanations of how and why the code works, so you can learn to adapt the problem-solving techniques to similar situations.The recipes in the PHP Cookbook range from simple tasks, such as sending a database query and fetching URLs, to entire programs that demonstrate complex tasks, such as printing HTML tables and generating bar charts.
