It can enable PHP execution error logging setting the file that logs error messages. The class provides an error database connection handler function that outputs a stack back-trace with the functions, arguments, file and lines of where an error occurs, as well the values of super-global variables $_GET, $_POST and $_FILES, and also the IP address of the current user accessing the site. The class may also enable of disable the output of error messages to Web pages and change the error reporting level. When used together with my Mysql class php mysql database (or any other mysql class that calls trigger_error when there was mysql_error) it can effectively log all mysql errors with the complete stacktrace what you can inspect from the logfile later on. Plus you can identify sql injections when someone's queries keep failing with error messages. You can also specify error codes that exit the script execution plus your own callback function that will be called before exiting (good to display some nice error page to users before exiting script execution).

Let´s say we would like to connect to a database via MySQLi inside a method or function. If the connection fails an error message and the error code should be displayed. In PHP 4 the error handling would have looked like this: function connect_to_mysql()
{$mysqli = @new mysqli('localhost', 'username', 'password', 'db_name');
if ($mysqli->connect_errno)
{
return false;}
return true;} To find out whether the database connection was successfully established or not we have to check the return value of the function. if(connect_to_mysql() == false)
{echo "A database connection could not be established.";
die();} Say we also have a function for inserting new data into our database or for selecting data from our database we would have to check for each function separately whether an error occurred or not. This is especially important when functions build upon one another. In PHP 5 the error handling within classes is now possible with exceptions. The class method connect_to_mysql() would look like this in PHP 5 with exceptions: function connect_to_mysql()
{$mysqli = @new mysqli('localhost', 'username', 'password', 'db_name');
if ($mysqli->connect_errno)
{
throw new Exception('A database connection could not be established.');}
return true;} In the script which invokes the class method the explicit validation of the return value is no longer necess
