PHP Server code
in file uploading ,I am done file uploading done through chunk ,please anyone help me send right code file uploading through chunk and relevant android file uploading code

<?php

if (empty($_FILES) || $_FILES['file']['error']) {
die('{"OK": 0, "info": "Failed to move uploaded file."}');
}

$chunk = isset($_REQUEST["chunk"]) ? intval($_REQUEST["chunk"]) : 0;
$chunks = isset($_REQUEST["chunks"]) ? intval($_REQUEST["chunks"]) : 0;

$fileName = isset($_REQUEST["name"]) ? $_REQUEST["name"] : $_FILES["file"]["name"];
$filePath = "uploads/$fileName";


// Open temp file
$out = @fopen("{$filePath}.part", $chunk == 0 ? "wb" : "ab");
//$out2 = @fopen("{$filePath}.part2", $chunk == 0 ? "wb" : "ab");
if ($out) {
// Read binary input stream and append it to temp file
$in = @fopen($_FILES['file']['tmp_name'], "rb");

if ($in) {
while ($buff = fread($in, 4096))
fwrite($out, $buff);
//print($out);
// echo sizeof($out);
} else
die('{"OK": 0, "info": "Failed to open input stream."}');

@fclose($in);

@fclose($out);

@unlink($_FILES['file']['tmp_name']);
} else
die('{"OK": 0, "info": "Failed to open output stream."}');


// Check if file has been uploaded

if (!$chunks || $chunk == $chunks - 1)
{
// Strip the temp .part suffix off
rename("{$filePath}.part", $filePath);
}


die('{"OK": 1, "info": "Upload successful."}');?>

Answer

i dont knw abt your code bt providing you both working codes: this is for all types of files i used it for image audio and for video files

Android:

new UploadFileAsync().execute("");



  private class UploadFileAsync extends AsyncTask<String, Void, String> {

    @Override
