How To Fix PHP Error Notice: Undefined variable: index

Today i have face this problem as listing below, and i have search a lot and try to fix my wamp server setting and waste my few professional hours. Im writing this so any other developer or designer not waste.

NOTE: This is just for those who wants to save their time to fix entire coding again to define variables. Otherwise i recommend must define variable before use them to avoid this error. 

this was the errors:

Notice: Undefined variable: q in in home.php on line 8

Notice: Undefined variable: module in home.php on line 11

you need to do some minor change on your php.ini file. please follow these steps

open your php.ini from wamp server and search “error_reporting = E_ALL & ~E_NOTICE“

if that module not active, please active it.

and close (replace) 

error_reporting  =  E_ALL

to

;error_reporting  =  E_ALL

if any place.

——– 2nd step —— 

if you wont found this. only found

error_reporting = E_ALL

so replace that to

error_reporting = E_ALL & ~E_NOTICE

once you done please restarts your Apache server or “wamp” then go back to the page where you were getting this error and refresh the web page and you should not see this error anymore.
