的file_get_contents失敗的Debian（lenny中）服務器上

不知道是否是因爲它是從生活中，但它已經運行一個網站和工作，直到最近（1周） - 服務器尚未更新，所以我不知道發生了什麼事打破劇本。的file_get_contents失敗的Debian（lenny中）服務器上

下面是我一直在Debian的服務器上運行（和失敗）測試腳本：

<?php 
$url = "http://www.andyloughran.co.uk/test.html"; 
echo $url."\n"; 
$test = file_get_contents($url); 
echo $test;

通常應該返回「NDY測試」或類似的東西。

然而，在Debian框，它只是超時。

我檢查，我可以wget的文件：

<?php 
exec('wget http://www.andyloughran.co.uk/test.html');

所以我不知道它是什麼在不工作的file_get_contents。

我檢查和allow_fopen_url被設置爲開。

我不能只是解決這個問題，但工作如何調試PHP爲了能夠找出自己的問題在未來與建議做。

捲曲是不是真的在此刻的選擇，因爲我更感興趣的是爲什麼它停止工作，而不是替代工作了。

謝謝！

什麼是錯誤信息？ –

也許不是一個PHP問題，但更像是一個DNS問題。 –

了allow_url_fopen =在php.ini中
檢查你的DNS，平www.andyloughran.co.uk
扔服務器從最近的窗口。

我真的想用throw server選項。 DNS和allow_url_fopen已打開。 – andylockran

我有同樣的problemn前一陣子。這是一個DNS問題。重新啓動Webserver幫助。

多數民衆贊成沒有幫助:( – andylockran

strace表明，DNS查找是成功的，因爲是http GET /test.html請求 - 它只是立即發送回該服務器.. – andylockran

file_get_contents不適用於URI。就試試這個：

$Stuff = file_get_contents($_SERVER['DOCUMENT_ROOT']."path/filename");

的file_get_contents會很高興「看到」本地和訪問路徑。它會將您的文件內容呈現爲一種「功能 - 感謝您」;）
