$auth_license = "1501402071-0-0-eabfb0fb52c429d4fa037585f7afd512";
$video = new \ZephirLib\Module\VideoEdit($service_uuid,$auth_license);
dump($video);
// 打印结果
object(ZephirLib\Module\VideoEdit)#3 (3) {
  ["service_uuid":protected] => string(36) "13c7c8e1-3ac2-41a6-95dc-ff954b431bbf"
  ["auth_license":protected] => string(47) "1501402071-0-0-eabfb0fb52c429d4fa037585f7afd512"
  ["auth_status"] => int(-1)
}
```

##  编译环境和依赖

* `re2c` 版本版本必须：`>= 0.13.6`    
* [安装 PHP7 ](http://www.cnblogs.com/tinywan/p/6607395.html)    
* [安装 zephir](https://github.com/phalcon/zephir)    
  ```bash
  sudo apt-get install php7.1-dev gcc make re2c autoconf
  git clone https://github.com/phalcon/zephir.git
  cd zephir
  sudo ./install -c
  ```
* [安装 php-zephir-parser](https://github.com/phalcon/php-zephir-parser)
  ```bash
  git clone git://github.com/phalcon/php-zephir-parser.git
  cd php-zephir-parser
  // 最好指定配置文件位置，当然也可以直接做一个软连接
  sudo ./install --phpize /usr/local/php-7.1.9/bin/phpize --php-config /usr/local/php-7.1.9/bin/php-config
  ```
* 修改PHP.ini配置文件
  ```bash
  $ sudo find / -name zephir_parser.so
  /usr/local/php-7.1.9/lib/php/extensions/no-debug-non-zts-20160303/zephir_parser.so
  ```
* 修改配置文件`vim /usr/local/php-7.1.9/etc/php.ini` 
  ```
  //添加以下内容
  [Zephir Parser]
  extension=zephir_parser.so
  ```

* 重启服务器
  ```
  sudo service php-fpm restart
  ```
* 配置检查

## 安装框架 <a name="如何编译" />
*   1、下载:
    ```bash
    git clone https://github.com/Tinywan/zephir-framework.git
    ```
*   2、编译:

```bash
    cd zephir-framework/zephirlib
    zephir build
    Compiling...
    Installing...
    Extension installed!
    Add extension=zephirlib.so to your php.ini
    Don't forget to restart your web server
    ```
*   3、添加扩展到`php.ini`:  
*   PHP 7  
    ```bash
        vim /usr/local/php-7.1.9/etc/php.ini
        # 添加内容
        extension=/usr/lib/php/20160303/zephirlib.so
    ```
    > 重启服务器：`sudo systemctl restart php-fpm.service`

*   PHP 5
    ```bash
    cd /usr/lib/php5/20121212/

sudo vim /etc/php5/mods-available/zephirlib.ini 
    // 添加内容
    extension=zephirlib.so
    ```
*   切换到目录`/etc/php5/fpm/conf.d`做一个软连接

```bash
    ln -s ../../mods-available/zephirlib.ini 20-zephirlib.ini
    ```
*   重启服务器：`sudo service php5-fpm restart`

*   [PHP 文件加密 Zend Guard Loader](http://www.cnblogs.com/tinywan/p/6888061.html)

*   4、重启`php-fpm`服务,查看扩展是否安装成功

> `/etc/php5/fpm/conf.d/20-zephirlib.ini`

##  常见问题

* 编译错误

```bash
  zephir build
  Preparing for PHP compilation...
  Preparing configuration file...
  configure: error: Cannot find php-config. Please use --with-php-config=PATH
  Compiling...
  sh: php-config: command not found
  kernel/filter.h:23:17: fatal error: php.h: No such file or directory
  ```
  > [Issue上如何解决以上错误](https://github.com/phalcon/zephir/issues/1653)  
  > 案例：`ln -sf /www/server/php/70/bin/php-config /usr/bin/php-config`

* 如何解决，查看命令行`（cli）`的配置文件，添加`zephir_parser`扩展

```bash
  $ php --ini
  Configuration File (php.ini) Path: /etc/php/7.1/cli
  Loaded Configuration File:         /etc/php/7.1/cli/php.ini
  Scan for additional .ini files in: /etc/php/7.1/cli/conf.d
  ...

vim /etc/php/7.1/cli/php.ini  
  //添加以下内容
  [Zephir Parser]
  extension=/usr/local/php-7.1.9/lib/php/extensions/no-debug-non-zts-20160303/zephir_parser.so

$ php -m | grep Zephir
  Zephir Parser
  ```
* re2c 版本过低，导致`php-zephir-parser`安装失败

* 安装 re2c 执行：`sudo apt-get install re2c`
  > `Ubuntu 14.04 LTS`系统默认安装  
  > Centos安装`yum install re2c`

* 安装`php-zephir-parser`错误

```bash
    sudo ./install
    error: minimal required version of re2c is 0.13.6
    ```
  * 查看当前版本

```bash
    www@:~$ re2c --version
    re2c 0.13.5
    ```
    > 注：`Zephir`和`php-zephir-parser`要求：`re2c >= 0.13.6`

* 下载安装最新版本

```bash
    wget https://github.com/skvadrik/re2c/releases/download/0.16/re2c-0.16.tar.gz

tar zxvf re2c-0.16.tar.gz

cd re2c-0.16

./configure

make
    make install

www@:~/tinywan/re2c-0.16$ re2c --version
    re2c 0.16
    ```
    > 注意：服务器系统内存不能小于：`512M`，否则没发编译。
