Thread: Let’s understand the different types of errors in PHP

There are mainly four types of error in PHP

Syntax error: This type of error occurs in PHP while there is a mistake in PHP syntax like missing semicolon, missing assignment, missing or extra parentheses, and missing curly braces.

Fatal error: when an object calls a class that time class does not exist. These errors cause immediate cancellations of the system, and PHP's conventional activities are to demonstrate them to the user when they take place.

Notice error: it is a non-critical error that PHP activates while booting a system. By default, such errors are not visible to the users.

Warning error: when you use an incorrect number of parameters in a function, a warning error occurs. Warning errors are more serious like trying to include () a file which does not exist. These mistakes are shown to the user, but they do not result in program cancellations.

These mistakes are shown to the user, but they do not result in program cancellations.

HostMonster no longer shows the warning on the page. Warnings are written to an error log stored in the site root folder, but you have to download the error log to read the warnings. It was more convenient for trouble shooting by the developer when the warnings were displayed, but if a visitor happened upon the page the warnings are ugly.

Not just ugly, they can be security wholes and great for hack attempts.
It would be vise to disable error reporting on production server/site as well, off course when all things are tested.
I always use this code on my all production scripts after they are tested:

PHP Code:

//for production server turn error reporting off if everythig is tested and working right, if you want to test turn it on or comment line below
error_reporting( 0 );
