php - Download file Curl with url var -


i download file curl. problem download link not direct, example:

http://localhost/download.php?id=13456

when try download file curl, download file download.php!

here curl code:

 ### function downloadtorrent($a) { $save_to = $this->torrentfolder; // set torrent folder download $filename = str_replace('.torrent', '.stf', basename($a)); $fp = fopen ($this->torrentfolder.strtolower($filename), 'w+');//this file save information $ch = curl_init($a);//here file downloading curl_setopt($ch, curlopt_encoding, "gzip"); // important curl_setopt($ch, curlopt_timeout, 50); curl_setopt($ch, curlopt_url, $fp); curl_setopt($ch, curlopt_header,0); // none header curl_setopt($ch, curlopt_binarytransfer,1); // binary trasfer 1 curl_exec($ch); curl_close($ch); fclose($fp); }

is there way download file without knowing path?

you may try curlopt_followlocation

true follow "location: " header server sends part of http header (note recursive, php follow many "location: " headers sent, unless curlopt_maxredirs set).

so result into:

function downloadtorrent($a) { $save_to = $this->torrentfolder; // set torrent folder download $filename = str_replace('.torrent', '.stf', basename($a)); $fp = fopen ($this->torrentfolder.strtolower($filename), 'w+');//this file save information $ch = curl_init($a);//here file downloading curl_setopt($ch, curlopt_encoding, "gzip"); // important curl_setopt($ch, curlopt_followlocation, true); curl_setopt($ch, curlopt_timeout, 50); curl_setopt($ch, curlopt_file, $fp); curl_setopt($ch, curlopt_header,0); // none header curl_setopt($ch, curlopt_binarytransfer,1); // binary transfer 1 curl_exec($ch); curl_close($ch); fclose($fp); }

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
