php升级代码检查

1、本地安装扩展

composer.json添加如下代码，然后执行composer update：

"require": {
 "phpcompatibility/php-compatibility": "*",
 "squizlabs/php_codesniffer": "*"
},
"scripts": {
   "post-install-cmd": "\"vendor/bin/phpcs\" --config-set installed_paths vendor/phpcompatibility/php-compatibility",
 "post-update-cmd" : "\"vendor/bin/phpcs\" --config-set installed_paths vendor/phpcompatibility/php-compatibility"
},
"prefer-stable" : true

2、生成代码分析报告,进入项目根目录，执行以下命令:

./vendor/bin/phpcs ./ --standard=PHPCompatibility --extensions=php --runtime-set testVersion 7.3 --report-full=./7.3.log
