First step is to load all the quotes you want into an array:

$quotes[] = "This is line 1";
$quotes[] = "This is line 2";
$quotes[] = "this is line 3";
$quotes[] = "This is another line";
$quotes[] = "This is yet another line";
$quotes[] = "Line 6";

Now get a handful of keys using array_rand:

$rand_keys = array_rand($quotes, 2);

We specified to get two random keys from the $quotes array – (You can grab more if you want, just change the "2")

Now that we have our random keys – you can either list them out one by one like this:

//show the first quote...
echo $quotes[$rand_keys[0]];
//show the second quote
echo $quotes[$rand_keys[1]];

Or you can loop through the keys like this:

foreach ($rand_keys as $value) {
echo $quotes[$value]."<br />";
}

That's all there is to it.

This will take all the values submitted in a form and store them in a session:

foreach($_POST as $k=>$v) {
$_SESSION[$k]=$v;
}

And when you're ready to dump the session values…

session_unset();// reset session array
session_destroy(); // destroy session.

for (var i=0; i < document.formname.dropdownboxname.length; i++) {
if (document.formname.dropdownboxname[i].value == "value") {
document.formname.dropdownboxname[i].selected = true;
}
}

Update Posting my comment in the main post – because this is the way to do it right: Use jQuery because it rules.

Use this plugin:
http://www.texotela.co.uk/code/jquery/select/

And this code:
$(document).ready(function() {
$(”#selectboxname”).selectOptions(”The Select Value”, true);
});

Solution: actually, I came up with two ways of doing this and both use .htaccess to pull it off.

1) I'm a gif but really I'm a php script
This one is fairly straightfoward. I put my script in a seperate directory, (that doesn't actually include any images!) and renamed it from filename.php to filename.gif (or filename.jpg) (Yes, I know it's not really an image file. Hang in there)

Then, in the htaccess file for JUST THAT FOLDER! (similar to this trick) I added this:
AddType application/x-httpd-php .php .jpg .gif

FYI – in your php file (that now looks like a .gif or .jpg) make sure you don't have any headers/text echoed, and at the end of the file add this to your php code:
header('Content-Type: image/gif');
@readfile( '/SERVERPATH/TO/A/REAL/IMAGE/spacer.gif' );

You can then include the "script" as if it were an image file, it will run the script, but only display a gif to the user.

You can even pass it variables like filename.gif?somevariable=somevalue&anotervariable=anothervalue, but there's another way to do that too without the ugly URL.

2) I'm a gif that's actually a php script super-powered with rewrite
Ok, starting from the beginning. You have your script (filename.php) in a folder, add the following to the .htaccess file in that folder:
RewriteEngine On
RewriteBase /
RewriteRule ^(.*)/(.*)/spacer.gif /YOURFOLDER/FILENAME.php?somevar=$1&anothervar=$2 [QSA]

Before we continue, I must tell you that I dont' completely understand rewrite rules. There's a LOT of holes in my knowledge. So if you have a better way, PLEASE post it in the comments. I would LOVE to be able to understand what the hell I'm doing. LOL.

OK, moving along. Now you can call your script by actually calling that "phantom" spacer.gif, with the variables in the URL as if they're directories like this:

http://www.yourdomain.com/YOURFOLDER/somevalue/anothervalue/spacer.gif

Again, make sure you have this at the end of you php code in your filename.php:
header('Content-Type: image/gif');
@readfile( '/SERVERPATH/TO/A/REAL/IMAGE/spacer.gif' );

<script type="text/javascript">
function applyToAll()
{
for (var i=0; i< document.YOURFORMNAME.length; i++) {
document.YOURFORMNAME[i].selectedIndex = document.YOURFORMNAME.NAMEOFMAINSELECT.selectedIndex;
}
}
</script>

So your select box probably looks like this:

<select name="NAMEOFMAINSELECT">
<option value="1">1</option>
<option value="2">2</option>
… etc. …
</select>

and then, next to the select box (which will be the one all the others are based on) put a link like this:

<a href="javascript:applyToAll()">Apply To All</a>

The remedy was specifying the databasename when referencing the table and avoiding using the mysql_select_db line altogether.

So instead of code that looked like this:
$databaseConnection = mysql_connect($databaseServer, $databseUsername, $databasePassword) or
die ('I can't connect to the database.');
mysql_select_db($databaseName,$databaseConnection);
$query = "SELECT * from tablename;";
$result = mysql_query($query);

I changed it to this and it seemed to work:
$databaseConnection = mysql_connect($databaseServer, $databseUsername, $databasePassword) or
die ('I can't connect to the database.');
$query = "SELECT * from " . $databaseName . ".tablename;";
$result = mysql_query($query,$databaseConnection);

Here are the instructions on how to integrate it into your (wordpress) comments:

First and foremost – if you want to add code, or use the full version – you can download that from Alex's site.

To use the "mini" version I made:

1) Download the js file and upload it to the root of your domain.

2) Open up your wp-comments.php page… Look for the beginning of the comments form – (search for <form in the file) and put this just above it:

<script src="/js_quicktags-mini.js" type="text/javascript"></script>

Look for the text area field for comments which looks like this <textarea name="comment" id="comment" cols="40" rows="6" tabindex="4"></textarea> and add this directly above it:

<script type="text/javascript">edToolbar();</script>

And add this BELOW the textarea field:

<script type="text/javascript">var edCanvas = document.getElementById('comment');</script>

This is the method I'm using on this site – although I added the "h3" tag just for the one I use, since that's what I use to stylize code on this site. You can easily add more… or start from scratch using Alex's.

$sql = "SELECT * FROM blogroll ORDER BY rand() LIMIT 1";

The problem I had was that it wasn't really random. When I had about 10 links in my blogroll, I hit refresh 80 times and got the first entry EVERY TIME. It worked better when I had more entries, but I still got that first one way too often. I tried to use the mt_rand() function, but it wouldn't work in the query. I had create a variable that used mt_rand() to pick a number within my range and then call that id in the query. So when I deleted a link or added a new one, it broke.

Then I found the following on php.net:

$sql = "SELECT * FROM blogroll ORDER BY rand(" . time() . " * " . time() . ") LIMIT 1";

This works MUCH better, and it's showing a lot of links and quotes that almost never showed up before. Hope that helps someone!
