Jnr PHP/Codeigniter Developer Interview Question:

Tell me what are the main error types in PHP and how do they differ?

Submitted by: Muhammad

In PHP there are three main type of errors:

☛ Notices – Simple, non-critical errors that are occurred during the script execution. An example of a Notice would be accessing an undefined variable.

☛ Warnings – more important errors than Notices, however the scripts continue the execution. An example would be include() a file that does not exist.

☛ Fatal – this type of error causes a termination of the script execution when it occurs. An example of a Fatal error would be accessing a property of a non-existent object or require() a non-existent file.
