Different Methods to Show Error Messages In PHP

PHP Errors

We use error functions to deal with error logging and error handling.

Types of Errors:

There are two types of errors:

1. Internal Error

These are logical errors in code.

2. External Error

These are errors related to the interactions of your code with the outside world.

Dealing with Error:

When we have figured out the error we can use the following ways to deal with them:

• Display the Error: This shows the error to the developer and/or user when the program is executed.
• Log the Error: Store the errors and review them from a textual log file
• Act on the Error: Each program will need a different type of action.
• Ignore the Error: This should continually be avoided.

Showing Errors:

There are Four possible ways:

• error_reporting()
• display_errors()
• log_errors()
• error_log string()

Turn off error reporting:

<?php
error_reporting(0);
?>

Report all errors:

<?php
error_reporting(E_ALL);
?>

<?php
ini_set("error_reporting", E_ALL);
?>

Report runtime errors:

<?php
error_reporting(E_ERROR | E_WARNING | E_PARSE);
?>

Report all Except E_Notice:

<?php
error_reporting(E_ALL & ~E_NOTICE);
?>
