Answer:

Check if "display_errors" is equal "on" in the php.ini or declare "ini_set('display_errors', 1)" in your script.
Then, include "error_reporting(E_ALL)" in your code to display all types of error messages during the script execution.

Enabling error messages is very important especially during the debugging process as you can instantly get the exact line that is producing the error and you can see also if the script in general is behaving correctly.
