任何語(yǔ)言的語(yǔ)法規(guī)范至關(guān)重要，特別是在團(tuán)隊(duì)協(xié)作過(guò)程中。

以下以php的laravel框架為主，通過(guò)git的pre-commit鉤子(hooks)來(lái)實(shí)現(xiàn)php語(yǔ)法規(guī)范檢測(cè)。

其流程無(wú)非是

1. 添加語(yǔ)法檢測(cè)器
2. 添加配置pre-commit(在git執(zhí)行g(shù)it commit操作開(kāi)始前所執(zhí)行的腳本)

開(kāi)始

1. 使用composer安裝php_codesniffer

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

2. 添加pre-commit
   使用s0enke大神的git-hooks ，將pre-commit (文件名沒(méi)有任何后綴)下載到本地項(xiàng)目的.git/hooks/下

3. 配置pre-commit

   修改pre-commit配置信息如下：

   // 檢測(cè)程序
   PHPCS_BIN=./vendor/bin/phpcs
   // 檢測(cè)php語(yǔ)法標(biāo)準(zhǔn)
   PHPCS_CODING_STANDARD=PSR2
   /// 忽略檢測(cè)文件
   PHPCS_IGNORE="*.blade.php,*.js,*.css"
   

   修改pre-commit權(quán)限(很重要)

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

其他

1. Php-psr2規(guī)范檢測(cè)

2. pre-commit文件代碼(為了方便讀者使用)
