Beware of crontab failure caused by relative paths of PHP files

As we know, the scripts that are added to crontab for execution may fail to be executed under crontab due to their environment variables and other reasons.

Tenfy has encountered a similar problem in the development of the QQ return front-end replenishment script. It usually focuses on whether the path of the shell script itself is an absolute path,

When the shell calls the PHP script, it ignores other PHP files contained in the PHP script and uses the relative path.

PHP cannot be executed normally:

Require ("../include/direct_connect_config.inc.php ");

 

After being changed to an absolute path, PHP is normal:

Require ("/data/web/order.fanli.qq.com/include/direct_connect_config.inc.php ");
