无法在服务器上测试PHP文件

i have a couple of servers running linux.

I installed httpd and PHP on CentOS 7 but everytime i type 192.168.10.83/info.php in web-browser to test phpinfo(); i see nothing...

Then i compiled apache and php on my local PowerPC machine and the same things happen.. what should i do? do i need to configure httpd.conf? every php file i open from browsers dont run...

Thanks
