//***Check whether torrents are complete***
$check = true;
while ($check) {
$c = 0;
foreach ($id as $value) {
$result = callTransmission(array("fields" => array("id", "name", "percentDone"), "ids" => array($value)), "torrent-get", $arr[1]);
preg_match('/"percentDone":[0-9.]+/i', $result[0], $matches);
$adii = substr($matches[0], 14);
$anuj = (int) ($adii * 100);
update_progress($anuj); //CALL FUNCTION
$anujstatus = "Download In Progress";
$downcomplete = "Download Finished";
anujstatus($anujstatus);
if ($anuj=='100') {
aditya(100);
anujstatus($downcomplete);
echo "<br><br><br><br> Download complete";
break 2;
}
if ($matches[0] == '"percentDone":1.0000')
$c++;
}


if ($c==count($id)) {

Your regex seems to be broken

PHP: 
preg_match('/"percentDone":[0-9.]+/i', $result[0], $matches);
That doesn't matches

Output the $result[0]
 
I don't know what script is this but the regex seems to do what it is intended to do. I think it isn't broken.
Maybe the problem is with the subject: $result[0] which doesn't contain the needed string?
 
Check the contents of the torrent file(Open in notepad or any text editor), And also if the torrent is running fine in transmission.
 
I think you posted that you updated transmission, maybe that changed callTransmission so the preg_match is broken.

try and print the array to see whats there?
print_r($result);


Someone else may fix it, im very basic with coding.

Execute this:

PHP: 
//***Check whether torrents are complete***
                $check = true;
                while ($check) {
                    $c = 0;
                    foreach ($id as $value) {
                        $result = callTransmission(array("fields" =>  array("id", "name", "percentDone"), "ids" => array($value)),  "torrent-get", $arr[1]);
print_r($result); exit;
                        preg_match('/"percentDone":[0-9.]+/i', $result[0], $matches);
                        $adii = substr($matches[0], 14);
                        $anuj = (int) ($adii * 100);
                        update_progress($anuj); //CALL FUNCTION
                        $anujstatus = "Download In Progress";
                        $downcomplete = "Download Finished";
                        anujstatus($anujstatus);
                        if ($anuj=='100') {
                            aditya(100);
                            anujstatus($downcomplete);
                            echo "<br><br><br><br> Download complete";
                            break 2;
                        }
                        if ($matches[0] == '"percentDone":1.0000')
                            $c++;
                    }


                    if ($c==count($id)) {
                        $check = false;
                        break 2;
                    }
                    sleep(5);
                }

$temp isn't declared.
try to uncomment to line above that one (by removing the //)

EDIT: sorry, I realized that this may remove the notice but won't solve the problem..
 
if (preg_match('/"percentDone":[0-9.]+/i', $result[0], $matches))
$temp = str_replace('"id":', "", $matches[0]);
// $temp="hlDr1wqu2ONtM3McVGHoVzfrkp2UgUcGwDt66IuxAe0 LBkru";
$id[0] = $temp;
Click to expand...

change to:
$temp= array();
if (preg_match('/"percentDone":[0-9.]+/i', $result[0], $matches))
$temp = str_replace('"id":', "", $matches[0]);
// $temp="hlDr1wqu2ONtM3McVGHoVzfrkp2UgUcGwDt66IuxAe0 LBkru";
$id[0] = $temp;
