This publication covers middle-tier programming with PHP, a server-side, HTML-embedded scripting language. One of its major attractions over Perl, JavaScript and other scripting languages is that PHP has a built-in database integration layer and seamless IP connectivity, with LDAP and TCP as well as the IMAP mail interface. It also features: practical experience and techniques, from installation and configuration of the PHP engine to advanced dynamic application design; definitive coverage of core PHP language and database addressing; practical e-commerce and business scripting including database application development, together with PHP and XML applications; and LDAP connectivity addressing.
