Phalcon Kernel

Phalcon Kernel(2012～)

! hNps://github.com/phalcon/cphalcon/blob/master/ext/kernel/README.md

Phalcon Kernel is a meta-‐framework on top of the Zend API helping to create PHP extensions in an easier way for a PHP developer. In order to build a fast and stable framework, we have created the Phalcon Kernel. The use of this API helps us to write C code in a PHP style. We have developed a number of funcmons to help the programmer to write code more interoperable with PHP in a easier way. Phalcon Kernel API is based on the Zend API, but we have added more features to facilitate us the work. Phalcon is a very large project, frameworks need to be developed and improved every day, Phalcon Kernel API helps us to write C code that is more stable and familiar to PHP developers.

Phalcon Kernel(2012～)

!   基於 ZEND API

!   提供大量 Helper funcmons / macros

! php style 的 c 開發風格

ZVAL (Phalcon)

Memory Management

! Phalcon Memory Management 簡化了 Zend Memory Managemant.

!   PHALCON_MM_GROW() 建立一個 phalcon memory entry 結構

!   PHALCON_INIT_VAR 建立並配置記憶體給 zval 並將其設為 null, 且將其指標的指標存至 phalcon memory entry.

!   PHALCON_MM_RESTORE 釋放所有經由 PHALCON_INIT_VAR 配置且 refcount =1 的記憶體

MM Sample

String

!   ZVAL_STRING() – Zend API

! concat_funcmon – Zend API

! Concat macro

PHALCON_INIT_VAR(month); ZVAL_STRING(month, "2012", 1); PHALCON_INIT_VAR(today_is); ZVAL_STRING(today_is, "Today is", 1);

PHALCON_INIT_VAR(first_part); concat_funcmon(first_part, today_is, month);

PHALCON_INIT_VAR(today); PHALCON_CONCAT_SVSV(today, "Today is", month, " ", day);

Concat Macros #define PHALCON_CONCAT_SV(result, op1, op2) \ #define PHALCON_CONCAT_SVS(result, op1, op2, op3) \ #define PHALCON_CONCAT_SVSV(result, op1, op2, op3, op4) \ #define PHALCON_CONCAT_SVSVS(result, op1, op2, op3, op4, op5) \ #define PHALCON_CONCAT_SVSVSV(result, op1, op2, op3, op4, op5, op6) \ #define PHALCON_CONCAT_SVSVSVS(result, op1, op2, op3, op4, op5, op6, op7) \ #define PHALCON_CONCAT_SVSVV(result, op1, op2, op3, op4, op5) \ #define PHALCON_CONCAT_SVV(result, op1, op2, op3) \ #define PHALCON_CONCAT_VS(result, op1, op2) \ #define PHALCON_CONCAT_VSV(result, op1, op2, op3) \ #define PHALCON_CONCAT_VSVS(result, op1, op2, op3, op4) \ #define PHALCON_CONCAT_VSVSVS(result, op1, op2, op3, op4, op5, op6) \ #define PHALCON_CONCAT_VSVSVSV(result, op1, op2, op3, op4, op5, op6, op7) \ #define PHALCON_CONCAT_VV(result, op1, op2) \ #define PHALCON_CONCAT_VVSV(result, op1, op2, op3, op4) \ #define PHALCON_CONCAT_VVV(result, op1, op2, op3) \ #define PHALCON_CONCAT_VVVVV(result, op1, op2, op3, op4, op5) \

大部份人對於 C

Zephir

大海賊 DSL 時代來臨

! Javascript ! CoffeeScript , LiveScript , TypeScript.

!   Java ! Scala , Groovy, Clojure

!   GNOME GObject C ! Vala

! Zend Engine C ! Zephir

Zephir

! Zephir -‐ Ze(nd Engine) Ph(p) I(nte)r(mediate)

!   A high level language that eases the creamon and maintainability of extensions for PHP.

! Zephir extensions are exported to C code that can be compiled and opmmized by major C compilers such as gcc/clang/vc++

CompilaLon Scheme

Hello World!

Hello World!

開頭少了 <?php 語法幾乎相同。

Hello World Generated C

Zephir -‐ PHP Syntax Like

Generated C

Zephir features

!   Stamc/Dynamic typing

!   Automamc memory management

!   Produce object-‐oriented libraries that can be used in PHP

!   Produce faster and beNer code that can be compiled by most important C-‐compilers: (gcc, vc++, clang)

!   The syntax of Zephir is inspired by C, PHP, Rust and Javascript.

!   Make the code more debugable ?????? (Without source map)

Basic

!   Organizing Code in Files and Namespaces !   Every file must contain a class (and just one class). !   Every class must have a namespace !   The directory structure must match the names of classes and

namespaces used. ( NOT Follow PSR-‐0)

Variable DeclaraLons

!   Declaramons

Variable Assignment

!   Assignment / Value Change

!   MUST Using let keyword.

Dynamic Types

Stamc Types

Arrays

Hashes

NOT PHP k => v NOT JSON

For Statement

!   A ‘for’ is a control structure that allows to traverse arrays or strings

!  

!   Keys in hashes can be obtained in the following way:

Calling FuncLons

!   To call a PHP funcmon, you can just refer its name in the Zephir

Create Zephir Project

! zephir init – Inimal zephir project and create config.json

! zephir [compile] – Compile and Install compiled .so .

Hello World!

Phalcon 2.0

! Phalcon 2.0 is currently being rewriNen in Zephir.

Is Zephir produc0on-‐ready

!   No, it’s in a very alpha stage.

! Phalcon Kernel is producmon-‐ready.

!   If you review generated c sources, it’s producmon-‐ready.

!   Keep Zephir in mind.
