本文主要向大家介绍了PHP语言如何添加PHP-psr2语法规范检测，通过具体的内容向大家展示，希望对大家学习php语言有所帮助。

任何语言的语法规范至关重要，特别是在团队协作过程中。

以下以php的laravel框架为主，通过git的pre-commit钩子(hooks)来实现php语法规范检测。

其流程无非是

1. 添加语法检测器

2. 添加配置pre-commit(在git执行git commit操作开始前所执行的脚本)

开始

1.使用composer安装php_codesniffer

composer global require "squizlabs/php_codesniffer=*" --dev

2.添加pre-commit
使用s0enke大神的git-hooks ，将pre-commit (文件名没有任何后缀)下载到本地项目的.git/hooks/下

3.配置pre-commit

修改pre-commit配置信息如下：

// 检测程序

PHPCS_BIN=./vendor/bin/phpcs// 检测php语法标准

PHPCS_CODING_STANDARD=PSR2/// 忽略检测文件

PHPCS_IGNORE="*.blade.php,*.js,*.css"

修改pre-commit权限(很重要)

chmod -R 755 .git/hooks/pre-commit

其他

1.Php-psr2规范检测

2.pre-commit文件代码(为了方便读者使用)
