Solution
The error reporting function error_reporting() specifies the reported errors in the php page.
To enable the reporting of errors set the error_reporting() function with the value E_ALL, i.e error_reporting(E_ALL)
To disable the reporting of errors set the error_reporting() function with 0, i.e error_reporting(0)
Also check the attribute display_errors = on in php.ini file
Finally in the above code, add the following
