Here is some production code that sends the file to an ftp (may be a good solution for you):
// This is the entire file that was uploaded to a temp location.
$localFile = $_FILES[$fileKey]['tmp_name'];
$fp = fopen($localFile, 'r');
// Connecting to website.
$ch = curl_init();
curl_setopt($ch, CURLOPT_USERPWD, "[email protected]:password");
curl_setopt($ch, CURLOPT_URL, 'ftp://@ftp.website.net/audio/' . $strFileName);
curl_setopt($ch, CURLOPT_UPLOAD, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 86400); // 1 Day Timeout
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_NOPROGRESS, false);
curl_setopt($ch, CURLOPT_PROGRESSFUNCTION, 'CURL_callback');
curl_setopt($ch, CURLOPT_BUFFERSIZE, 128);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($localFile));
curl_exec ($ch);
if (curl_errno($ch)) {
$msg = curl_error($ch);
}
else {
$msg = 'File uploaded successfully.';
}
curl_close ($ch);
$return = array('msg' => $msg);
echo json_encode($return);
