A PHP interpreter is a software program responsible for parsing, compiling, and executing PHP code. Choosing the right PHP interpreter can improve application performance and security.
Developed and maintained by Zend Technologies, it is the official PHP interpreter. It is widely used in commercial applications, offering stable performance and strong compatibility.
Developed by Facebook, HHVM compiles PHP code into bytecode to increase execution speed, mainly used for high-performance applications.
Developed by SAP, PHPng focuses on improving concurrency, scalability, and security. It is still in development and not widely adopted yet.
Created by the Phalcon Framework team, Zephir allows PHP code to be compiled into C extensions, providing near-native execution performance, ideal for high-performance PHP applications.
Developed by Facebook, Hack is a PHP dialect with static typing, enhancing type safety and performance, suitable for large-scale applications.
The PHP interpreters introduced here each have unique features. From the official Zend Engine to high-performance HHVM and Zephir, and the type-safe Hack, developers can choose the appropriate runtime environment based on project needs to improve PHP application performance and security.
