Just to expand on that, when you're passing arguments, you don't need any quotes at all around variables, ie

PHP Code:


			
mysql_connect($dbn, $user, $pass);

...and in the case of strings, variables won't be parsed inside of single quotes anyways, only inside of double quotes;

PHP Code:


			
$var = 'world!';

echo 'Hello, $var'; // will display Hello, $var
echo "Hello, $var"; // will display Hello, world!

-m
