three basic types of runtime errors in PHP:

1. Notices: These are trivial, non-critical errors that PHP encounters while executing a
script for example, accessing a variable that has not yet been defined.
By default, such errors are not displayed to the user at all although 
you can change this default behavior.

2. Warnings: These are more serious errors for example, attempting to include() a file 
which does not exist. By default, these errors are displayed to the user, but they do 
not result in script termination.

3. Fatal errors: These are critical errors  for example, instantiating an object of a non-existent class,
or calling a non-existent function. These errors cause the immediate termination of the script, and PHP 
default behavior is to display them to the user when they take place.
