PHP-无法访问外部URL [英] PHP - Cannot access external URLs

问题描述

由于流量很大，我最近升级了我网站的服务器.在新服务器上，PHP的某些方面似乎已损坏.我有一个非常具体的代码无法正常工作.但是，由于版权原因，我只能向您显示与您无关的非机密信息:

I have recently upgraded my website's servers due to high amounts of traffic. On the new servers, some aspects of PHP seem to be broken. I have a very specific code that isn't working. However, due to copyright reasons, I can only show the non-confidential equivalent to you:

<?php
echo file_get_contents('http://www.google.com');
?>

此代码在升级之前绝对完美正常工作，现在在这里或那里有些奇怪的设置使该代码无法工作.

This code worked absolutely flawlessly before the upgrade, and now some odd setting here or there has prevented this code for working.

具体来说，无论您输入哪个外部URL，file_get_contents函数都根本不起作用(file_get_contents('index.php')可以正常工作)；

To be specific, the file_get_contents function doesn't work at all, regardless of what external URL you put in (file_get_contents('index.php') works fine);

感谢您的帮助！

更新#1
此代码也不起作用:

UPDATE #1
This code does not work either:

<?php
ini_set("allow_url_fopen", "On");
echo file_get_contents('http://www.google.com');
?>

更新#2
该代码有效...

UPDATE #2
This code works...

<?php
    ini_set("allow_url_fopen", "On");
    $url = "http://www.google.com/";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $data = curl_exec($ch);
    curl_close($ch);
    echo $data;
?>

...但是如果我尝试执行simplexml_load_file($data);，则会发生坏事.如果我simplexml_load_file('http://www.google.com') ...

... but if I try to do simplexml_load_file($data); bad things happen. Same if I do simplexml_load_file('http://www.google.com')...

推荐答案

尝试使用CURL.

$url = "http://google.com/";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);

内容将存储在$ data中.

The contents will be stored in $data.
