（php5.4以上支持）

一、php.ini配置：

session.upload_progress.enabled = on

session.upload_progress.cleanup =on

session.upload_progress.prefix = "upload_progress_"

session.upload_progress.name = "PHP_SESSION_UPLOAD_PROGRESS"

session.upload_progress.freq = "1%"

session.upload_progress.min_freq = "1"

二、客户端：

<input type="hidden" name="<?php echo ini_get('session.upload_progress.prefix') ?>" value="text">

</form>

</div>

jQuery(function ($) {

$("#form1").submit(function () {

setTimeout(progressbar, 100);

});

function progressbar() {

$("#progress").show();

$.get("{:url('progress')}", {"<?php echo ini_get('session.upload_progress.name'); ?>": "test"}, function (data) {

var i = parseInt(data);

$("#bar").css({"width": i + '%'});

$("#label").text(i + "%");

if (i < 100) {

setTimeout(progressbar, 100);

}

});

}

});

</script>

三、服务器端：

upload.php

session_start();

if(is_uploaded_file($_FILES['file1']['tmp_name']){

$_SESSION['isupload']=1;

move_uploaded_file($_FILES['file1']['tmp_name'],'./upload/'.iconv('utf-8','gbk',$_FILES['file1']['name']));//iconv()为支持中文文件名

}

progress.php

session_start();

$key=ini_get("session.upload_progress.prefix").$_GET[ini_get("session.upload_progress.name")];

if(!empty($_SESSION[$key])){

return ceil($_SESSION[$key]['bytes_processed']/$_SESSION[$key]['content_length']*100);

}else if($_SESSION['isupload']){

$_SESSION['isupload']=0;

return 100;

}else{

return 0;

}
