PHP - Randomly Display With Counting

Hello,

Just to keep things looking fresh I have a series of over a hundred images that displays randomly, five across, toward the header of my site.

See here... Jump around the site or refresh the page now and then...you will see the images will randomly fail to show through.

Without a doubt they are also loading slower than they should too.

As far as I can tell, everything should be fine! See below code. I think the only thing messing it up is the random image function itself is quirky.

$imagecount = 0;


while($imagecount < 5){



$start = "1";


$random = rand($start, $total);


$image_name = $random . $file_type;


echo "<img class=\"scrollingimage\" alt=\"\" height=\"105\" width=\"124\" src=\"$image_folder/$image_name\" />";

$imagecount ++;

}

Hi,

I have an array of items and I randomly want to remove one from the array. What's the easiest way to go about this?

Hello all I have a form for a meeting unable to attend log.
An attendee calls in to say they will not be able to make meeting and the form saves the reason etc into a db and infroms (via emails) all staff members who would have attended of the cancelation.

It works but for some reason the record saves twice in the db on occasion and I'm unsure why.

The loggers fills in some deatils on a form called log.php and then clicks save which goes to the following page:

Code: [Select]
<?php
$auth = $_COOKIE['auth'];
$login_id = $_COOKIE['login_id'];
header("Cache-Control:no-cache");
if(!$auth == "ok")
{ header("Location:../log_index.php");
exit();
}
include("../php_include/connection.php");
include("../php_include/functions.php");

$absent_date = $_POST['absent_date'];
$call_time = $_POST['hour'] .":". $_POST['mins'];
$reason = (! get_magic_quotes_gpc ()) ? addslashes ($_POST['reason']) : $_POST['reason'];
$reason = fix_quotes($reason);
$log_date = date ("d/m/Y");
$log_time = date("G:i");
$attendee_id = str_replace("\'","'",$_POST['attendee_id']);
$attendee_name = str_replace("\'","'",$_POST['attendee_name']);
$attendee_email = str_replace("\'","'",$_POST['attendee_email']);
$sent = $_POST['sent'];

if( !$sent )
{
echo( "Error - Data not sent from main form.<br><form action=\"log.php\"><input type=\"submit\" name=\"back\" value=\"Back\"></form>" );
}
else 
{

Can anyone shed some light?
 Or suggest code improvements?
Many Thanks

I have retrieved 5 values from a database table...
The table is such as->
tmeta_id team_id 1 1 2 2 3 3 4 4 5 5 Code: [Select]
Array (
[0] => 1
[1] => 2
[2] => 3
[3] => 4
[4] => 5 ) .. and this array I have named $nonrandom_teamno. using shuffle() I have rearranged the array, the new array being $random_teamno, which is such as the following->
Code: [Select]
Array (
[0] => 3
[1] => 4
[2] => 5
[3] => 2
[4] => 1 )I am having real problems reinserting this into the SQL tables...
I have been trying the foreach loop below...
Code: [Select]
for($i = 1; $i < (count($nonrandom_teamno)+1); $i++)
    {
        $db->query("UPDATE ancl_teammeta SET team_id ='$random_teamno[$i]' WHERE tmeta_id='$nonrandom_teamno[$i]'");       
    }It puts numbers back in the database, but not random ones. Please help me with the correct query I need!! Thank you..

I am having an issue in which fopen randomly generates either timeout or "failed to open stream" errors when trying to get stock quotes from yahoo finance.

Here's an example.

<b>Warning</b>:  fopen(http://finance.yahoo.com/d/quotes.csv?s=NFLX&amp;f=sl1d1t1c1ohgv&amp;e=.csv) [<a href='function.fopen'>function.fopen</a>]: failed to open stream: HTTP request failed!

This issue occurs sporadically; sometimes it's fine, other times it errors out causing the quote to fail.

Any ideas on how I can resolve this? Thanks very much.
