PHP Phrasebook

Description:

If you were traveling in Spain, but couldn't speak Spanish very well, you'd probably carry a Spanish dictionary with you. If you are a PHP developer who needs a portable reference guide for frequent use in your job, the PHP Phrasebook is perfect for you. The PHP Phrasebook is actually a pocket guide that is jam-packed with useful and essential PHP code "phrases" for the PHP developer's everyday use. The code is flexible, so it can be easily adapted to your needs and mulitple situations, and your time isn't wasted wading through chapters of tutorial lessons and extraneous information. The phrasebook covers PHP 5 and is relevant for PHP 4.
