[align=center]Hello guys. I see everyday php codes without error handlers showing the default errors so I decided to make a tutorial for error handlers..[/align]

[size=large][align=center][b][i]Examples of default errors above[/i][/b][/align][/size]

[align=center]

    Notice: Undefined variable: example in \xampp\htdocs\example.php on line 19

[/align]
[align=center]

    Parse error: syntax error, unexpected '<' in \xampp\htdocs\example.php on line 22

[/align]

[size=xx-large][i][align=center]Making a custom error handler[/align][/i][/size]

[size=large][b][align=center]Try running this code below[/align][/b][/size]

    <?php



echo "$example"; //$example variable doesn't exist so we get error!



?>

[size=large][b][align=center]You will get this error[/align][/b][/size]

    Notice: Undefined variable: example in \xampp\htdocs\example.php on line 8

[align=center]Hmm,If you had a serious public script running would you want your visitors to get this error or a another default PHP error?[/align]
[align=center][size=large][i]I don't think so..Let's prevent it![/i][/size][/align]

[size=large][b][align=center]Add to the previous script the code below(This code should be in the beginning of the script)[/align][/b][/size]

    function Error() //We create a function named "Error"

	{

	die("Variable cannot be found<br>"); //Script ends and displays the message "Variable cannot be found"

	}

set_error_handler("Error"); //We set our function as error handler!

[align=center][size=large]So we should have this code now[/size][/align]

    <?php



function Error() //We create a function named "Error"

	{

	die("Variable cannot be found<br>"); //Script ends and displays the message "Variable cannot be found"

	}

set_error_handler("Error");//We set our function as error handler!



echo "$example"; //$example variable doesn't exist so we get error!



?>

[align=center][size=large]Now you should take this error[/size][/align]

    Variable cannot be found

[align=center][size=large]Congratulations[/size]
You made your first basic error handler![/align]
