Thanks for your info but this script is not useless (for you it might be) consider average users have not your knowledge and this script will help them, they dont know about versions of sub-drivers and sql servers or how to correct them and this is normal and understandable, in conclusion you know more things than average user and you can ignore this script, but you cant call it useless because it actually helps, i would not recommend using old versions of php (before 7) speed, stability and security are very low commonly (but also depends on developer, code and usage).
