The proxy server is tinyproxy on debian

$context = stream_context_create([

推荐答案

我推荐cURL去做这个。在stackoverflow上的某个地方，用户说这个并且我完全同意。

I would recommend cURL to do this. Somewhere on stackoverflow a user said this and I totally agree.

file_get_contents（）是一个简单的螺丝刀。非常适合简单的GET
请求，其中标头，HTTP请求方法，超时，cookiejar，
重定向和其他重要事项无关紧要。带有setopt
的cURL是一个几乎所有你能想到的选项的powerdrills。

file_get_contents() is a simple screwdriver. Great for simple GET requests where the header, HTTP request method, timeout, cookiejar, redirects, and other important things do not matter. cURL with setopt is a powerdrills with almost every option you can think of.

<?php

$url = 'https://www.google.com';
// to check your proxy
// $url = 'http://whatismyipaddress.com/';
$proxy = '50.115.194.97:8080';

// create curl resource
$ch = curl_init();

// set options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // read more about HTTPS http://stackoverflow.com/questions/31162706/how-to-scrape-a-ssl-or-https-url/31164409#31164409
curl_setopt($ch, CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');

// $output contains the output string
$output = curl_exec($ch);

// close curl resource to free up system resources
curl_close($ch); 

echo $output;

?>
