PHP pulling random line

[jollyhumper]

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)

<?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:

It took a while before I tested it, but FYI, it works :-)
(Of course you knew it worked, I mean, it works for me too :-D )

Thanks again, appreciated

...and yes I know there's useless code in there

$f_contents = file("random_source.txt");
$line = $f_contents[rand(0, count($f_contents) - 1)];
?>
