Thanks for the details! That's all I was curious about.

Performance issue, just plain wrong? If $var contains a string that appears in your localized message catalogs, and you want the localized version printed, then __($var) is correct and echo $var is wrong. If $var is just a variable that does not contain a localizable string, then echo $var is correct and __($var) is wrong. __() is usually used with inline strings, like __('Hello') so that a parser can extract all the localizable strings from your sources and put them in your message catalog template, from which they can then be merged into all your message catalogs and then translated using tools like poEdit or, if you're careful, a plain text editor. Read gettext documentation for more information. In CakePHP 1.3, __() has a second parameter, a boolean that says whether to return the data. The default is false, in which case it echoes the data. This default has always seemed peculiar to me, and in CakePHP 2.0, it's gone, and __() always returns data; if you want to echo it, you echo it using echo __(...). -- Our newest site for the community: CakePHP Video Tutorials http://tv.cakephp.org Check out the new CakePHP Questions site http://ask.cakephp.org and help others with their CakePHP related questions.
