php 版本升級后需要對代碼進行兼容性檢測

來到需要檢測代碼的目錄下 需要提前安裝 docker

執行

docker run --rm -v $(pwd):/app vfac/php7compatibility 7.3 . --ignore=vendor --extensions=php,module,inc -d memory_limit=4G |tee -a php7.3.result

--ignore 需要忽略的文件夾

--extensions 可以傳入需要檢查的文件后綴 如果不傳 檢查所有

-d memory_limit 傳入內存分派大小

可以查看官方文章

https://vfac.fr/projects/php7compatibility

 

另外這篇文章講了如何使用 phpcs

但是我沒有弄成功

找個文件夾 執行  composer require "squizlabs/php_codesniffer=*" 

然后 進入文件夾下的  ./vendor/squizlabs/php_codesniffer/CodeSniffer/Standards 

執行

 git clone https://github.com/wimg/PHPCompatibility.git 

之后

 ./vendor/bin/phpcs -i 

看到這里面並不包含 我們需要的 PHPCompatibility

則添加一下

phpcs --config-set installed_paths ./vendor/squizlabs/php_codesniffer/CodeSniffer/Standards/PHPCompatibility/PHPCompatibility

也有人說這個路徑是  ./vendor/squizlabs/php_codesniffer/CodeSniffer/Standards/ 

但是我試了  ./vendor/bin/phpcs -i  還是不行

The installed coding standards are PSR1, PSR2, PEAR, PHPCS, MySource, Zend, Squiz, PSR1, PSR2, PEAR, PHPCS, MySource, Zend and Squiz

其他的倒是很好用

./vendor/bin/phpcs --standard=PSR2 --runtime-set testVersion 7.1 ~/script/php/for.php

得到
