PHPCompatibility检测php版本语法兼容

Posted 2020-09-19 andyChan

直接上步骤：

 1 cd /datas/htdocs/
 2 mkdir phpCompatibility
 3 cd PHPCompatibility/
 4 curl -s http://getcomposer.org/installer | php
 5 ./composer.phar require "squizlabs/php_codesniffer=2.*"
 6 cd vendor/squizlabs/php_codesniffer/CodeSniffer/Standards
 7 git clone https://github.com/wimg/PHPCompatibility.git
 8 cd /datas/htdocs/PHPCompatibility/
 9 ./vendor/bin/phpcs -i
10 ./vendor/bin/phpcs --standard=PHPCompatibility --runtime-set testVersion 7.1 /datas/htdocs/thinkphp/

 上面第10行是那thinkphp做测试，结果类似：

1 FILE: ...s/htdocs/thinkphp/Library/Vendor/TemplateLite/class.compiler.php
2 ----------------------------------------------------------------------
3 FOUND 1 ERROR AND 1 WARNING AFFECTING 2 LINES
4 ----------------------------------------------------------------------
5  159 | ERROR   | preg_replace() - /e modifier is deprecated since PHP
6      |         | 5.5 and removed since PHP 7.0
7 ----------------------------------------------------------------------
