You use it as index in the string, so it is automatically converted to an integer: "Middle" -> 0 So you assign "pass" to the first character of $first. And as you can only assign other single characters to a single char, the first char of "pass" is used. > echo "$first[$second]"; // prints: P That should be a lowercase 'p' (see above) Summary: You thought too complex and thus stumbled over another feature of PHP :) -- Christian Reiniger LGDC Webmaster (http://sunsite.dk/lgdc/) What luck for the rulers that men do not think. - Adolf Hitler
