Sure, here's a gist I found on Google:
https://gist.github.com/jayarjo/5846636
<?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", $chunk == 0 ? "wb" : "ab");
if ($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, $buff);
} else
die('{"OK": 0, "info": "Failed to open input stream."}');
#fclose($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."}');
