<?php
// Define a custom error handler that will save all errors into a database.
function db_err_handler($errno, $errstr, $errfile, $errline, $errcontext) {
	// Open a fresh database connection for this, don't want to reuse
	// any that might have caused the original error.
	$db = @mysql_connect('localhost', 'my_user', 'my_password') 
		or die('Error Logging DB Failure: ' . mysql_error());
	mysql_select_db('my_database');

	// Now, we need to serialize the error context to store it, since it's
	// a huge array holding all of the variables that exist.  
	$ized = serialize($errcontext);
	
	// Ok, we should now be able to insert this error into the table.
	mysql_query("
	    insert into error_log
	        (errno, errstr, errfile, errline, errcontext)
	    values
	        ({$errno}, '{$errstr}', '{$errfile}', {$errline}, '{$ized}')
	    ");

	// Go ahead and close the database connection.
	mysql_close($db);
	
	// Now, if this was a fatal error of some sort, just output 'ERROR'
	// and kill the process.  Otherwise, let it go on as if it didn't happen
	// The only two of these that we will see, are ERROR or USER_ERROR
	if (($errno == E_ERROR) || ($errno == E_USER_ERROR)) {
		die("ERROR");
	}

// Now go ahead and register this as the error handler:
set_error_handler('db_err_handler');
