Hi,

What I'm trying to do is create a script that generates a random list of cars whenever it is run. I have a list of available cars in a MySQL database. I'm just not sure how to get php to generate a list of, say, 20 cars, that are randomly picked from the cars in the database. I may also want to add other statistics like MPG (also already in the database). Can anyone show me how to do this? And is it possible to format the returned data in a table or div format?

Thanks in advance

Hi, I have a script to add images to my tabel and and upload them to my server, I have managed to get the upload script to rename the image with a 5 digit random number on the end to prevent overwriting, the only problem I can't seem to be able to add the same name to my tabel. Any ideas? Thanks in advance.

So I found this code from someone else on here who posted about creating a random string. I've copied the code for myself but when I upload php page to my server and view source... there is no php code. Essentially, i see no randomly generated text. what am i missing?

Code: [Select]
<?php
function genRandomString() {
    $length = 5;
    $characters = array_merge(range(0,9),range('a','z'),range('A','Z'));
$string = "";
    for ($p = 0; $p < $length; $p++) {
        $string .= $characters[mt_rand(0, count($characters)-1)];
    }
    return $string;
}
?>
