Hello PHP World After many Hours of worryness :=)
I have found the Solution for Resume or Pause Uploads
In this Code Snippet it is the Server Side not Client on any Desktop Programm you must use byte ranges to calculate the uploaded bytes and missing of total bytes.
Here the PHP Code
<?php
$CHUNK = 8192;
try {
if (!($putData = fopen("php://input", "r")))
throw new Exception("Can't get PUT data.");
$tot_write = 0;
$tmpFileName = "/var/dev/tmp/PUT_FILE";
if (!is_file($tmpFileName)) {
fclose(fopen($tmpFileName, "x")); if (!($fp = fopen($tmpFileName, "w")))
throw new Exception("Can't write to tmp file");
while ($data = fread($putData, $CHUNK)) {
$chunk_read = strlen($data);
if (($block_write = fwrite($fp, $data)) != $chunk_read)
throw new Exception("Can't write more to tmp file");
$tot_write += $block_write;
}
if (!fclose($fp))
throw new Exception("Can't close tmp file");
unset($putData);
} else {
if (!($fp = fopen($tmpFileName, "a")))
throw new Exception("Can't write to tmp file");
while ($data = fread($putData, $CHUNK)) {
$chunk_read = strlen($data);
if (($block_write = fwrite($fp, $data)) != $chunk_read)
throw new Exception("Can't write more to tmp file");
$tot_write += $block_write;
}
if (!fclose($fp))
throw new Exception("Can't close tmp file");
unset($putData);
}
if ($tot_write != $file_size)
throw new Exception("Wrong file size");
$md5_arr = explode(' ', exec("md5sum $tmpFileName"));
$md5 = $md5sum_arr[0];
if ($md5 != $md5sum)
throw new Exception("Wrong md5");
} catch (Exception $e) {
echo '', $e->getMessage(), "\n";
}
?>
