using wordwrap with pdf_show_xy

philosophia

i'm using the following code to display a variable called $test in a pdf document

pdf_show($pdf,"Essay 1");

pdf_show_xy($pdf,$test, $startx,680);

-this works, if the value of $test is only a few characters long, but when $test is a long text area of up to 800 words, what happens is my text runs off the page

i tried using wordwrap() to format the large text area to fit within the pdf document

pdf_show($pdf,"Essay 1");

$newtext = wordwrap( $test, 80 );

pdf_show_xy($pdf,$newtext, $startx,680);

-this doesn't seem to work. the pdf looks exactly the same w text running off the page.

anyone ever run into this type of situation? any words of advice would be appreciated

thanks

i've tried a bunch of different functions
off of http://php.planetmirror.com/manual/en/function.wordwrap.php

they work when spitting out the text onto html, but not when used with pdf_show
