这篇文章主要为大家详细介绍了php结合web uploader插件实现分片上传文件, 采用大文件分片并发上传,极大的提高了文件上传效率,感兴趣的小伙伴们可以参考一下,最近研究了下大文件上传的方法,找到了webuploader js 插件进行大文件上传,大家也可以参考这篇文章进行学习:《Web Uploader文件上传插件使用详解》
使用
使用webuploader分成简单直选要引入
- <!--引入CSS-->
- <link rel="stylesheet" type="text/css" href="webuploader文件夹/webuploader.css">
- <!--引入JS-->
- <script type="text/javascript" src="webuploader文件夹/webuploader.js"></script>
HTML部分
- <div id="uploader" class="wu-example">
- <!--用来存放文件信息-->
- <div id="thelist" class="uploader-list"></div>
- <div class="btns">
- <div id="picker">选择文件</div>
- <button id="ctlBtn" class="btn btn-default">开始上传 </button>
- </div>
- </div>
初始化Web Uploader
- jQuery(function() {
- $list = $('#thelist'),
- $btn = $('#ctlBtn'),
- state = 'pending',
- uploader;
- uploader = WebUploader.create({
- // 不压缩image
- resize: false,
- // swf文件路径
- swf: 'uploader.swf',
- // 文件接收服务端。
- server: upload.php,
- // 选择文件的按钮。可选。
- // 内部根据当前运行是创建,可能是input元素,也可能是flash.
- pick: '#picker',
- chunked: true,
- chunkSize:2*1024*1024,
- auto: true,
- accept: {
- title: 'Images',
- extensions: 'gif,jpg,jpeg,bmp,png',
- mimeTypes: 'image/*'
- }
- });
upload.php处理
以下是根据别人的例子自己拿来改的php 后台代码
- header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
- header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
- header("Cache-Control: no-store, no-cache, must-revalidate");
- header("Cache-Control: post-check=0, pre-check=0", false);
- header("Pragma: no-cache");
- if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
- exit; // finish preflight CORS requests here
- }
- if ( !emptyempty($_REQUEST[ 'debug' ]) ) {
- $random = rand(0, intval($_REQUEST[ 'debug' ]) );
- if ( $random === 0 ) {
- header("HTTP/1.0 500 Internal Server Error");
- exit;
- }
- }
- // header("HTTP/1.0 500 Internal Server Error");
- // exit;
- // 5 minutes execution time
- @set_time_limit(5 * 60);
- // Uncomment this one to fake upload time
- // usleep(5000);
- // Settings
- // $targetDir = ini_get("upload_tmp_dir") . DIRECTORY_SEPARATOR . "plupload";
- $targetDir = 'uploads'.DIRECTORY_SEPARATOR.'file_material_tmp';
- $uploadDir = 'uploads'.DIRECTORY_SEPARATOR.'file_material';
- $cleanupTargetDir = true; // Remove old files
- $maxFileAge = 5 * 3600; // Temp file age in seconds
- // Create target dir
- if (!file_exists($targetDir)) {
- @mkdir($targetDir);
- }
- // Create target dir
- if (!file_exists($uploadDir)) {
- @mkdir($uploadDir);
- }
- // Get a file name
- if (isset($_REQUEST["name"])) {
- $fileName = $_REQUEST["name"];
- } elseif (!emptyempty($_FILES)) {
- $fileName = $_FILES["file"]["name"];
- } else {
- $fileName = uniqid("file_");
- }
- $oldName = $fileName;
- $filePath = $targetDir . DIRECTORY_SEPARATOR . $fileName;
- // $uploadPath = $uploadDir . DIRECTORY_SEPARATOR . $fileName;
- // Chunking might be enabled
- $chunk = isset($_REQUEST["chunk"]) ? intval($_REQUEST["chunk"]) : 0;
- $chunks = isset($_REQUEST["chunks"]) ? intval($_REQUEST["chunks"]) : 1;
- // Remove old temp files
- if ($cleanupTargetDir) {

- die('{"jsonrpc" : "2.0", "error" : {"code": 100, "message": "Failed to open temp directory."}, "id" : "id"}');
- }
- while (($file = readdir($dir)) !== false) {
- $tmpfilePath = $targetDir . DIRECTORY_SEPARATOR . $file;
- // If temp file is current file proceed to the next
- if ($tmpfilePath == "{$filePath}_{$chunk}.part" || $tmpfilePath == "{$filePath}_{$chunk}.parttmp") {
- continue;
- }
- // Remove temp file if it is older than the max age and is not the current file
- if (preg_match('/\.(part|parttmp)$/', $file) && (@filemtime($tmpfilePath) < time() - $maxFileAge)) {
- @unlink($tmpfilePath);
- }
- }

- }

- }
- while ($buff = fread($in, 4096)) {
- fwrite($out, $buff);
- }
- @fclose($out);
- @fclose($in);
- rename("{$filePath}_{$chunk}.parttmp", "{$filePath}_{$chunk}.part");
- $index = 0;
- $done = true;
- for( $index = 0; $index < $chunks; $index++ ) {
- if ( !file_exists("{$filePath}_{$index}.part") ) {
- $done = false;
- break;
- }
- }
- if ( $done ) {
- $pathInfo = pathinfo($fileName);
- $hashStr = substr(md5($pathInfo['basename']),8,16);
- $hashName = time() . $hashStr . '.' .$pathInfo['extension'];
- $uploadPath = $uploadDir . DIRECTORY_SEPARATOR .$hashName;
