PHP pulling random line

Hi

Let's say a text document has 30 lines in it.
How could PHP be used to randomly pull one of those lines, each time the web page is built?
I'm looking to pull a random category or partner, or something, on my pages.

PHP is not my strongest side

Thanks anyhow

I actually know this one!!! (not that I wrote it lol)

Code:
<?php
$file = "/home/domain.com/public_html/textfile.txt";
$banners = file($file);
srand((float) microtime() * 1235689);
$selected = array_rand($banners);
$SelBanner = trim($banners[$selected]);
if ($SelBanner=="") {
$SelBanner = trim($banners[0]);
};
echo $SelBanner;
?>
That will pull 1 line from the text file & insert it on the page. I've used it as a cheap banner rotator for years:
