PHP fopen() 达到重定向限制错误

执行以下代码块时：

foreach($eventfiles as $eventfile)
{
    if($eventfile['filename'])
    { 
        $file = $eventfile['filepath'];
        // Open File
        if( !($fp = fopen($file, "r")))
        {
            echo '<br>CAN NOT READ FILE.';
            exit;
        }
        // Read data from the file into $data
        $data = "";
        while (!feof($fp)) $data .= fread($fp,1024);
        query("update event_rtab set html = '".escape($data)."' where id = {$eventfile[id]}");
    }
    if($eventfile['eventType']=='email')
    {
        query("INSERT INTO event_email_rtab (event_id,subject) values ($eventfile[id],'".escape($eventfile[email_subject])."')");
    }
}

脚本失败并出现以下错误：

fopen(测试.html) [function.fopen]：打开失败流：已达到重定向限制，中止于 /data/www/example.com/public/test.php 第 843 行

什么原因导致此错误以及如何更正它？

When executing the following block of code:

foreach($eventfiles as $eventfile)
{
    if($eventfile['filename'])
    { 
        $file = $eventfile['filepath'];
        // Open File
        if( !($fp = fopen($file, "r")))
        {
            echo '<br>CAN NOT READ FILE.';
            exit;
        }
        // Read data from the file into $data
        $data = "";
        while (!feof($fp)) $data .= fread($fp,1024);
        query("update event_rtab set html = '".escape($data)."' where id = {$eventfile[id]}");
    }
    if($eventfile['eventType']=='email')
    {
        query("INSERT INTO event_email_rtab (event_id,subject) values ($eventfile[id],'".escape($eventfile[email_subject])."')");
    }
}

The script fails with the following error:

fopen(test.html)
[function.fopen]: failed to open
stream: Redirection limit reached,
aborting in
/data/www/example.com/public/test.php
on line 843

What causes this error and how can I correct it?

您尝试打开的文件位于哪里？它们是在本地文件系统上还是您尝试通过 HTTP(S) 访问它们？

如果您正在使用某种网络协议包装器，则此错误很可能与从脚本到要打开的文件的途中过多（HTTP - 如果是 HTTP(S) 协议）重定向有关。默认重定向限制应为 20。由于 20 个重定向相当多，因此文件名本身可能存在一些错误（例如导致另一端的网络服务器执行一些拼写检查重定向）或其他服务器配置错误或存在一些安全措施或...

如果您觉得需要扩展 20 个可以使用流上下文的重定向。

$context = array(
    'http'=>array('max_redirects' => 99)
);
$context = stream_context_create($context);
// hand over the context to fopen()
$fp = fopen($file, 'r', false, $context);
// ...

请参阅：

Where are the files located you are trying to open? Are they on the local filesystem or are you trying to access them via HTTP(S)?

If you're using some network protocol wrapper then, this error is most likely connected with too many (HTTP - in case of the HTTP(S) protocol) redirects on the way from your script to the file you want to open. The default redirection limit should be 20. As 20 redirects are quite alot there could be some error in the filename itself (causing e.g. the webserver on the other end to do some spellcheck-redirects) or the other server is misconfigured or there are some security measures in place or...

If you feel the need to extend the 20 redirects you could use a stream context.

$context = array(
    'http'=>array('max_redirects' => 99)
);
$context = stream_context_create($context);
// hand over the context to fopen()
$fp = fopen($file, 'r', false, $context);
// ...
