Better than substr is to cast the variable to be an int (int)$firstpercent would force the variable to be an integer, chopping off any decimals it may have. Other than that I don't really know what to say. Determining percentage is more a math thing than php. Maybe take a look at other poll scripts out there (there's tons of them). Keep in mind both substr and casting to an integer are essentially always rounding down. So if your values are 58.9, 12.6, and 28.5 then you'll lose 2 percent after all is said and done.

[PHP] array/mysql problems
I've been trying to get this to work all night with no luck. I've gotten a
similar version to work, with the only real difference being I didn't use
mysql (I just plugged some stuff in). But other than that I can't see the
difference. Basically I'm trying to pull stuff out of a database, get an
average for each entry, and then sort the entries by the average from
largest to smallest. I don't get any output other than the basic html in
other parts of the file. No error messages. I've tried sticking in echos all
over the place testing stuff looking for the problem and I can't find
anything. Any ideas?
$link = mysql_connect(host, user, pass);
mysql_select_db(db);
$result = mysql_query(SELECT * FROM table);
$sitearray = array();
$dummysite = new siteinfo();//siteinfo is a class containing just
variables
while ($query_data = mysql_fetch_object($result))
{
$dummysite-days = (int)((time() - $query_data-startday)/86400);
if ($dummysite-days 1) $dummysite-days = 1;
$dummysite-sitename = $query_data-sitename;
$dummysite-tvisits = $query_data0-visits;
$dummysite-avisits = $dummysite-tvisits/$dummysite-days;
$sitearray[$dummysite-avisits] = $dummysite;
}
echo trtd;
$sitearray = array_reverse($sitearray);
//just trying to get some output, any output
for ($i = 1; $i != 100; $i++)
echo $sitearray[$i]-sitename;

[PHP] weird caching problem
I'm calling an image through a php file, but when I make changes to the
image, I can't get them to show. For some reason the old image is getting
cached somewhere, and none of the standard remedies are working (refreshing,
deleting cache, etc). What does work is changing the value of $icon and then
reflecting that change in my code. But that's not ideal for what I'm doing.
Any ideas?
Here's how I'm calling the image in php:
?php
//image.php
{
// some mysql stuff
}
if ($icon == 'a') header(Location:
http://www.rcnchicago.com/~tortus/goombaw.gif;);
else header(Location: http://www.rcnchicago.com/~tortus/goombab.gif;);
?

[PHP] working with remote images
It looks like my attempt to send this bounced. Which is fine, since I've now got a slightly different question. I'm working on a network for my site and others related to it. We want to keep track of which sites are the most popular by having everyone place on their site something to the effect of img src=http://www.mywebsite.com/image.php?somevariables=here; I want to then have image.php make note of which site requested it and add to their tally in the database. Then feed them the image requested. But my concern is if that image is on my server I'll be getting a lot more bandwidth. So I'm wondering if its possible to then have image.php tell the requesting server to grab their own copy of the image and load it up? I have a feeling php will grab the image from the other site's server, download it to my server and then upload it back to them.

Is it possible to have on a webpage something like img src=image.php?website=awebsite.com and then image.php takes note of the website variable, does a few things with mysql, then passes on the image that is wanted, utilizing something from the gd library?
