MySQLChecker
============

[](#mysqlchecker)

Checks a MySQL database for orphaned records or invalid foreign keys, i.e., keys pointing to missing rows.

Create [MySQLi](http://www.php.net/manual/en/mysqli.construct.php) object and then check database named `blog`:

```
$mysqli = new mysqli('localhost', 'root', 'password');
checkForeignKeys($mysqli, 'blog');

```

Or without parameter it checks all databases:

```
checkForeignKeys($mysqli);

```
