Zephir

Welcome to Zephir, an open source, high level/domain specific language designed to ease the creation and maintainability of extensions for PHP with a focus on type and memory safety.

Some features¶

Zephir’s main features are:

Type system	dynamic/static
Memory safety	pointers or direct memory management aren’t allowed
Compilation model	ahead of time
Memory model	task-local garbage collection

A small taste¶

The following code registers a class with a method that filters variables returning its alphabetic characters:

namespace MyLibrary; /**  * Filter  */ class Filter { /**  * Filters a string returning its alpha characters  *  * @param string str  */ public function alpha(string str) { char ch; string filtered = ""; for ch in str { if (ch >= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z') { let filtered .= ch; } } return filtered; } }

The class can be used from PHP as follows:

<?php $filter = new MyLibrary\Filter(); echo $filter->alpha("01he$l.lo?/1"); // prints hello
