从技术上看php脚本是在cron所在的地方运行的；前任.如果 cron 在/bin/cron 中，则该语句将在/bin/includes/common.php 中查找 common.php.

Technically seen the php script is run where cron is located; ex. If cron was in /bin/cron, then this statement would look for common.php in /bin/includes/common.php.

是的，您可能必须使用完整路径或使用 set_include_path

So yeah, you'll probably have to use fullpaths or use set_include_path

set_include_path('/home/username123/public_html/includes/');
require 'common.php';
