PDO::quote--does it work?

Hi everyone,

I have a question (duh).
Does PDO::quote actually work?
On the PDO::quote page (http://us3.php.net/manual/en/pdo.quote.php), it says the return value is a string 'theoretically safe' to pass into a query.
Also, in an example, this is the output of a string that has gone through PDO::quote: 'Naughty '' string'
That string looks like it would cause an error.
What's up with this?
I don't get how that string is even theoretically safe.
Can someone illuminate me?

Thanks,
-Tony

 

Create a php.ini file with the following:
magic_quotes_gpc = Off extension=pdo.so extension=pdo_mysql.so

 

That doesn't really answer my question...
