First php post...
Hi there,
I'm writing some code for my website to list people listening to my music. I
have a loop for an array that dosen't seem to display all people. most of
the time it resuses to go past 11 even though there are more people. I've
created a small loop just to list the IP addresses as a test, which works.
ie:
$loop = 0; //dummy loop
variable
while($loop != $currentlisteners){ //while loop for listeners
echo "$loop - $hostname[$loop]<br>";
$loop++;
}
When I use the same loop again to get more detailed info, the $loop only
counts from 0 to about 10 or sometimes more. It's never consistant. I never
encountered this in any other language before. The $currentlisteners is
never altered during the loop execution. What I've done was echo $loop to
see it's progress throughout the loop. This is so frustrating.
EG:
--------------------------------------------------------
$loop = 0; //dummy loop variable
while($loop != $currentlisteners){ //while loop for listeners
// Get the surfer's ip address
$addr = $hostname[$loop];
$ip = sprintf("%u", ip2long($addr));
// Load array with start ips
$row = 1;
while (($buffer = fgets($handle, 4096)) !== FALSE) {
$array[$row] = substr($buffer, 1, strpos($buffer, ",") - 1);
$row++;
}
// Locate the row with our ip using bisection
$row_lower = '0';
$row_upper = $row;
while (($row_upper - $row_lower) > 1) {
$row_midpt = (int) (($row_upper + $row_lower) / 2);
if ($ip >= $array[$row_midpt]) {
$row_lower = $row_midpt;
} else {
$row_upper = $row_midpt;
}
}
// Read the row with our ip
rewind($handle);
$row = 1;
while ($row <= $row_lower) {
$buffer = fgets($handle, 4096);
$row++;
}
$buffer = str_replace("\"", "", $buffer);
$ipdata = explode(",", $buffer);
echo "<td><font size=1><center>$loop <img
src='../WhosBeenListening/Flags/$ipdata[4].gif' width='18' height='12'>
$ipdata[6] - $hostname[$loop]</td>";
echo "<td><font size=1><center>$useragent[$loop]</td>";
$sec = $connecttime[$loop];
$hours = intval(intval($sec) / 3600);
$hms = str_pad($hours, 2, "0", STR_PAD_LEFT).':';
$minutes = intval(($sec / 60) % 60);
$hms .= str_pad($minutes, 2, "0", STR_PAD_LEFT). ':'; // then add to $hms
(with a leading 0 if needed)
$seconds = intval($sec % 60); // seconds by 60 and keep the
remainder
$hms .= str_pad($seconds, 2, "0", STR_PAD_LEFT); // add to $hms, again
with a leading 0 if needed
echo "<td><font size=1><center>$hms</td>";
echo "<td><font size=1><center>$underruns[$loop]</td>";
echo "</tr>";
$loop++; //update loop variable
}
--------------------------------------------------------
Is there something wrong with the $loop variable itself? It has not been
declared (if I can use this term in PHP) in any way. I am using PHP 5 on my
computer at this time. Here is the link for my site (xex.ca) that shows the
scripting results. If there are more than 10 people listening to that one
perticular stream then you will see the problem. If I get it working then I
will use the same code for all the streams to get a total info page.
http://74.113.12.208:29992/Xex/Radio/Stats/scastdetail.php. I am altering
and adding to code I found on the net.
Any help is appriciated.
