php上传文件并显示上传进度的方法

这篇文章主要介绍了php上传文件并显示上传进度的方法,实例分析了php传输文件及显示传输进度的技巧,非常具有实用价值,需要的朋友可以参考下

本文实例讲述了php上传文件并显示上传进度的方法。分享给大家供大家参考。具体如下：

记得上传文件的时候要大点，不然还没看出来就上传完了，并且上传的文件不要太大，上G的就算了，2G的我试了，PHP受不了，我测试的是300多M的，记得要调整小php.ini参数啊 “选文件=》提交=》获取信息”要一气呵成哦^ ^

$prefix = ini_get('session.upload_progress.prefix');

$name = ini_get('session.upload_progress.name');

$key = $prefix . $name;

session_start();

if (isset($_POST['get_info'])) {

$logo = $prefix . $_POST['logo'];

exit(json_encode($_SESSION[$logo]));

} elseif ($_POST) {

echo '<script>var finashed = true;</script>';

}

var sto = null;

var progress = null;

function getUploadInfo()

{

$.post("index.php", {"get_info": 1, "logo": "test"}, function(data)

{

data = eval("(" + data + ")");

progress = parseInt(parseInt(data.bytes_processed) * 10000 / parseInt(data.content_length)) / 100 + "%";

document.getElementById("show_info_div").innerHTML = progress;

sto = setTimeout("getUploadInfo()", 1000);

});

}

if (typeof(finashed) !== "undefined")

{

document.getElementById("show_info_div").innerHTML = "100.00% (上传成功！)";

}

希望本文所述对大家的php程序设计有所帮助。
