Question

我正在使用APC（php）来显示进度条，但我陷入了困境。我使用过这个链接，所有内容都是写的，并且安装了APC。

http://www.johnboy.com/php-upload-progress-bar/

我使用相同的代码，修改路径很少，以存储我的链接

的图像

http://way2enjoy.com/modules/music/try/try/upload.php

一切似乎都是正确的，但我案例中的进度条显示NaN％

我检查了显示此错误的错误日志

 [23-Jun-2012 20:20:26 UTC] PHP Warning:  Division by zero in /home/XXXXXXX/public_html/modules/music/try/try/upload_frame.php on line7

我的upload_frame.php代码是

<?php

$url = basename($_SERVER['SCRIPT_FILENAME']);

if(isset($_GET['progress_key'])) {
$status = apc_fetch('upload_'.$_GET['progress_key']);
    echo $status['current']/$status['total']*100;

die;
}

?>

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.js"    type="text/javascript"></script>
<link href="style_progress.css" rel="stylesheet" type="text/css" />

<script>
$(document).ready(function() { 


setInterval(function() 
    {
$.get("<?php echo $url; ?>?progress_key=<?php echo $_GET['up_id']; ?>&randval="+ Math.random(), { 

},
    function(data)
        {
            $('#progress_container').fadeIn(100);   
            $('#progress_bar').width(data +"%");    
            $('#progress_completed').html(parseInt(data) +"%"); 
        }
    )},500);    
});

upload.php代码

Answer 1

您是否阅读了project's page：

中的重要提示

重要提示：确保在php.ini中包含apc.rfc1867 = on

它对我有用。

Answer 2

显然$status['total']为零。

这样做：

if ($status['total'] == 0) {
    echo "0";
}
else {
    echo $status['current']/$status['total']*100;
}

php apc除以零错误
