PHP Agent does not work

Hi guys,

I got problem when install PHP Agent. I follow instruction in here https://docs.appdynamics.com/display/PRO42/Install+the+PHP+Agent+using+a+Shell+Script

Please note that I install php agent download from appdynamics(from my controller, it got retrieve error). The version are 4.9.2 on both controller & agent.

Below are output after install :

I have check the Controller information, and make sure the firewall does not block anything.

However, My Controller does not seen any information about PHP Agent. I do not see php agent logs too.

PS : About the permission, I changed to 777, restart service. Check the java too :
