Why won't httpd start?

Question

CentOS

httpd won't start after server reboot.
After the php was updated. But the error didn't go away!
I enter the command service httpd restart
I get in response!

Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details

.
I enter systemctl status httpd.service
