Sample class to escape a MySQL input value

There was quite a simple but effective snippet I came across recently
that highlights how PHP getters (magic methods) can be useful.

Please don’t use this code as it is, as it’s for illustrative purposes
only; it doesn’t check for magic quotes that the server may be using,
and you may want to do additional purification of the data according
to the field’s content. However, I do think it’s a useful example of
how classes can be used effectively, and this could be expanded, in
theory, to add a static type for input type, that’s initialised during
__construct(), which could make it a little more dynamic.

class dbQuoteStr
{
    function __get($value)
    {
        return mysql_real_escape_string($value);
    }
}
$dbQuoteStr = new dbQuoteStr();

To use the above class, all you need to do is:

mysql_query("SELECT * FROM users WHERE name LIKE
'{$dbQuoteStr->$name}' LIMIT 10");
