Crontab not executing script with cURL

Question

I have a cron that's set to run every ten minutes that works fine if I execute the file manually by entering

php register.php

But, my cron will not execute this file once it includes anything cURL related. My cron is as follows

*/10 * * * * /usr/bin/php /var/www/html/register.php 

I know that the cron is getting the correct file because at the very top of it, I put php's mail function to send me an email so that I know it was executed. But, anything cURL related will not execute. There aren't any global variables or server variables in the script, so that isn't the reason. I've checked both the crontab and the php error logs and nothing is there pertaining to this issue.

Answer 1

尝试在脚本的开头添加以下内容：

chdir(dirname(__FILE__));
