Hi Mustafa, after trying to test all day, in fact this php56 is not compatible with the mtn, eventhough I've tried to edit the all php.ini, but still in vain. Therefore, I will be back to php54 again. But there are obstacles, when I run "yum replace php56 --replace-with=php54u -y" I am getting error like this:
[root@server1 ~]# yum replace php56 --replace-with=php54u -y
Loaded plugins: fastestmirror, priorities, protectbase, replace
Replacing packages takes time, please be patient...
Error: Package 'php56' is not installed.
[root@server1 ~]#
Am I wrong..? Please correct me if it wrong command.
