PHP 大文件上传进度条实现

  目前我知道的方法有两种,一种是使用PHP的创始人 Rasmus Lerdorf 写的APC扩展模块来实现(,另外一种方法是使用PECL扩展模块uploadprogress实现( 我这里举两个分别实现的例子供参考,更灵活的应用根据自己需要来修改。


  • 安装APC,参照官方文档安装,可以使用PECL模块安装方法快速简捷,这里不说明
  • 配置php.ini,设置参数 apc.rfc1867=1 ,使APC支持上传进度条功能,在APC源码说明文档里面有说明
  • 代码范例:
    [coolcode lang=”php”]
    if ($_SERVER[‘REQUEST_METHOD’] == ‘POST’) { //上传请求
    $status = apc_fetch(‘upload_’ . $_POST[‘APC_UPLOAD_PROGRESS’]);
    $status[‘done’] = 1;
    echo json_encode($status); //输出给用户端页面里的ajax调用,相关文档请自己寻找
    } elseif (isset($_GET[‘progress_key’])) { //读取上传进度
    $status = apc_fetch(‘upload_’.$_GET[‘progress_key’]);
    echo json_encode($status);
    } else {

  uploadprogress 模块实现方法:

  • 使用PECL模块安装方法安装该模块
  • php.ini里面设置 uploadprogress.file.filename_template = “/tmp/upd_%s.txt”
  • 代码范例:
    [coolcode lang=”php”]
    if (is_uploaded_file($_FILES[‘upfile’][‘tmp_name’])) {
    $upload_dir = ‘your_path/’;
    $ext = strrchr($_FILES[‘video’][‘name’], ‘.’);
    $sessid = $_POST[‘UPLOAD_IDENTIFIER’] ;
    $tmpfile = $upload_dir . $sessid;
    $sessfile = $upload_dir . $sessid .$ext;
    if (move_uploaded_file($_FILES[‘upfile’][‘tmp_name’],$tmpfile)) {
    } else {
    } else {

    } elseif (!empty($_GET[‘sessid’])) {
    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”);

    $unique_id = $_GET[‘sessid’];
    $uploadvalues = uploadprogress_get_info($unique_id);

    if (is_array($uploadvalues)) {
    echo json_encode($uploadvalues);
    } else {

    } else {

  1. Love is patient; love is kind; love is not envious pr boastful or arroga nt or rude. It does not insist on its own way; it is not irritable or re sentful; it does not rejoice in wrongdoing, but rejoices in the truth. I t bears all things, hopes all things, endures all things. Love never ends.
