Php servers not working in mi4i

have an mi4i 16gb model. i installed androphp and also ksweb server trial for my php application. its running in my moto g 2nd gen. But in this phone it gives error no input file specified. After searching for long time i found that there is no permission to execute php commands on internal storage. so is there any way to give execute permission. I have rooted my phone.

Mysql server access is working, phpmyadmin is working.
