Subject: [PHP-DEV] Pulling a random
image
Hello everyone...
I have been working on this random function for awhile now.. and it is close
to being complete. It works as for a random function. But what my goal was is
to make it where it goes through all the images before showing a random twice.
Kind of like you put all the images in a bucket, and random select one out of
the bucket while you eyes are closed, once you take it out of the bucket you
put it on the table till there is no images left in the bucket, then you fill
the bucket again and start over.
Now... I thought
the following function did that, but for some reason it is not... I might have
just missed a line of code, or misspelled something, but I come to you
guys/gals to be more second pair of fresh eyes to see if you can find where I
made a mistake.
Thanks..

function
getRandomUser()
{
static $itemarray;
if
(empty($itemarray)) {
$connection = mysql_pconnect(SQL_SERVER,
SQL_UID, SQL_PWD);
mysql_select_db(SQL_DB,
$connection);
$sql = "select * from user where valid = 1
and inrotation = 1";
$query = mysql_query($sql);
while($thisrow = mysql_fetch_array($query)) {
$itemarray[] = $thisrow;
}
}
if (sizeof($itemarray) == 0)
return
Array('userid'=>'-1', "photo_name"=>'', "photo_num"=>'',
"counter"=>'', "size"=>'');
srand((double)microtime()*1000000);
$row =
rand(0, sizeof($itemarray)- 1);
$toreturn = $itemarray[$row];
$itemarray = array_splice($itemarray,$row,1);
return $toreturn;
}
