The manual errata is for submissions of text to be included into the manual, so chances are way, way better that someone will come across your note on the mailing list than in the manual errata. :) Please make sure to read the instructions at http://www.php.net/manual/add-note.php before adding another note. As to your problem--what you are describing would happen if trans() was *echoing* its text. The way you are trying to use it above would only work if trans() was *returning* its text. This is because when the PHP parser hits that line in the code, it has to figure out what all the text is before it can echo it. Thus, trans() gets called before the echo happens. So any text echoed from that function gets printed first, then the function returns, and the original echo occurs. Whew. Not the clearest explanation I've ever perpetrated. :) Blame the beer.
