Simple, to the point, and compact, the second edition of PHP Pocket Reference is thoroughly updated to include the specifics of PHP 4, the language's latest version. It is both a handy introduction to PHP syntax and structure, and a quick reference to the vast array of functions provided by PHP. The quick reference section organizes all the core functions of PHP alphabetically so you can find what you need easily.
