There is no PHP in Asterisk proper (and also Asterisk proper is never an AMI client, only a server, which is why this can't come from Asterisk.

You cannot create /dev/dahdi/ctl on CentOS except by starting dahdi - any attempt to do so directly should fail. This suggests that one of your problems is that you haven't installed dahdi properly (the startup script hasn't been installed, for example). For pure Asterisk, this would just cause degraded functionality and performance.
