使用工具来检查项目代码对PHP7的兼容情况

使用 PHP_CodeSniffer + PHPCompatibility
PHP_CodeSniffer
PHP_CodeSniffer对PHP，JavaScript和CSS文件进行标记，并检测违反已定义的一组编码标准的行为。
https://github.com/squizlabs/PHP_CodeSniffer

PHPCompatibility
PHP兼容性检查
https://github.com/PHPCompatibility/PHPCompatibility
更多PHPCompatibility相关内容，请参考 https://www.sitepoint.com/quick-intro-phpcompatibility-standard-for-phpcs-are-you-php7-ready/

安装和运行

按照官方文档进行安装
先安装PHP_CodeSniffer
再安装插件PHPCompatibility

composer global require “squizlabs/php_codesniffer=*”
phpcs –config-set installed_paths /data/wwwroot/php/PHPCompatibility
phpcs –config-set installed_paths “D:\projects\php\PHPCompatibility”

查看是否安装上
phpcs -i
#The installed coding standards are MySource, PEAR, PSR1, PSR12, PSR2, Squiz, Zend and PHPCompatibility
执行检查
phpcs –standard=PHPCompatibility –runtime-set testVersion 7.0 /data/wwwroot/project/ >phpcs.log
#执行的过程会有些慢，慢慢等吧

根据phpcs.log中的日志,解决error级别的错误

FILE: \data\wwwroot\project\Common\function.php

FOUND 3 ERRORS AFFECTING 2 LINES

9 | ERROR | Function split() is deprecated since PHP 5.3 and removed since PHP 7.0; Use preg_split() instead
11 | ERROR | Function eregi() is deprecated since PHP 5.3 and removed since PHP 7.0; Use preg_match() instead

11 | ERROR | Extension ‘ereg’ is deprecated since PHP 5.3 and removed since PHP 7.0; Use pcre instead

再加上手动按照PHP版本逐级检查不兼容

PHP5.4.x 》 PHP5.6.x

从 PHP 5.4.x 迁移到 PHP 5.5.x

不向后兼容的变更的检查
检查 pack() 和 unpack() pass

PHP 5.5.x 中废弃的特性的检查
preg_replace() 函数中用到的 /e 修饰符现在被弃用。可以使用 preg_replace_callback() 函数来替代。
mcrypt 的相关函数

PHP 5.5.x 》 PHP5.6.x

从PHP 5.5.x 移植到 PHP 5.6.x
不向后兼容的变更的检查
严格的 json_decode()

PHP 5.6.x 》 PHP7.0.x

从PHP 5.6.x 移植到 PHP 7.0.x
不向后兼容的变更的检查
ereg相关函数
split()

测试

把主要业务功能都过一遍测试

升级部署问题

方式1：容器部署：php-fpm改用docker的方式部署，这样比较方便多版本切换和回滚
方式2：传统部署：部署新服，业务流量切过去，原有服暂时不要销毁，等业务没问题后再慢慢销毁原有服, 如果是云平台应该为所有将要销毁的系统做一个快照以备不时之需

用PECL自动安装Redis扩展、Swoole扩展

yum install GeoIP GeoIP-devel GeoIP-data
pecl install igbinary
pecl install redis
pecl install swool

yum install GeoIP GeoIP-devel GeoIP-data

pecl install igbinary

pecl install redis

pecl install swool

编译安装PHP7并安装Redis扩展Swoole扩展

在编译php7的机器上已经有编译安装过php5.3以上的版本,从而依赖库都有了

本php7是编译成fpm-php 使用的,

如果是apache那么编译参数应该为

--with-apxs2=/usr/local/apache/bin/apxs

1	--with-apxs2=/usr/local/apache/bin/apxs
