Compile the PHP source code into the JVM bytecode compiler: JPHP

JPHP is a javac-like compiler that can compile PHP source code into JVM bytecode. Then, the PHP program is run on the Java VM. It supports many PHP5.3 + features. JPHP is similar to JRuby and Jython.

Supported: JDK 1.6 + (OpenJDK, Oracle ).


JPHP is not a replacement of the Zend PHP engine or Facebook HHVM. It does not want to implement the zend runtime library (such as Curl and PRCE ). This item aims:

  1. Use Java objects in PHP
  2. Improve performance through JIT and JVM
  3. Use a better runtime library to replace the ugly runtime library of Zend PHP
  4. PHP is not only used to develop Web applications
  5. Also: unicode for strings and threads
  • JIT (2x-10x faster PHP 5.4)
  • Optimizer (constant expressions, inline functions, etc .)
  • Using java libraries and classes in PHP code.
  • Unicode for strings (UTF-16, like in Java)
  • Threading, Sockets
  • Environment architecture (like sandbox objects in runkit zend extension ).
  • GUI (based on Swing, improved-more flexible layouts)
  • Embedded cache system for classes and functions
  • Optional Hot Reloading for classes and functions
