JPHP has the zend legacy extension, but you will have problems when you will work with it. We don't recommend to use this extension and try to use a better approach from the JPHP Standard Library.

One of the project goals is:

Replacing the ugly runtime library of Zend PHP with a better runtime library.

The all classes of the std library have a namespace that starts with php\:

• php\lib - util classes for primitive types.
• php\io - IO, Files, Streams.
• php\sql - classes for working with SQL databases (like PDO).
• php\net - classes for working with network, sockets, http and ftp protocols.
• php\time - date and time classes
• php\android - classes for Android OS
• php\webserver - classes to implement own embedded web server (instead of mod_php + apache)
• php\util - misc classes - regex, scanners, flows, shared memory, etc.
• php\lang - system classes
• php\concurrent - classes for multithreading
• php\xml - for writing and reading xml

Our migration guide helps you use alternative classes and functions from JPHP Standard Library.

• Math
• Strings
• Arrays and Iterators
• Files and Streams
• Regex (PCRE)
• JSON
• XML
• Apache and mod_php
