What are the different types of errors in PHP ?

Here are 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


    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's default behavior is to display them to the user when they take place.
