PHP Trigger Error

PHP trigger_error generates an error, warning, notice message. Basic format of the trigger_error is as follows:

boolean trigger_error ( string $error_message <, int $error_type = E_USER_NOTICE >)

The return data type of this method is Boolean, first argument is necessary to mention and the next one is optional (that's why it is enclosed within angular bracket )

This method is used to trigger an user level error message, it can be displayed along with the built-in-error handler, or with a user defined function.

Example of PHP Trigger Error Handling:

<?php

$div=0;

if($div==0){

trigger_error("Cannot divide by zero");

}

?>

Output:

Notice: Cannot divide by zero in ../trigger_error.php on line 4
