如何使用PHP来获得一个网页到一个变量 [英] How to use PHP to get a webpage into a variable

问题描述

我想从网上下载一个网页，它是允许的，当你使用的是简单的浏览器如Firefox做的，但是当我用的file_get_contents服务器拒绝，并回复它理解命令，但不允许出现这样下载。

I want to download a page from the web, it's allowed to do when you are using a simple browser like Firefox, but when I use "file_get_contents" the server refuses and replies that it understands the command but don't allow such downloads.

那么怎么办？我想我在一些脚本（Perl的）的方式看到了通过创建一个用户代理和饼干，这使得服务器认为你的脚本是一个真正的Web浏览器，使你的脚本像一个真正的浏览器。

So what to do? I think I saw in some scripts (on Perl) a way to make your script like a real browser by creating a user agent and cookies, which makes the servers think that your script is a real web browser.

有没有人有这样的想法，它可以怎么做？

Does anyone have an idea about this, how it can be done?

推荐答案

使用卷曲。

<?php
        // create curl resource
        $ch = curl_init();

        // set url
        curl_setopt($ch, CURLOPT_URL, "example.com");

        //return the transfer as a string
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);


        // set the UA
        curl_setopt($ch, CURLOPT_USERAGENT, 'My App (http://www.example.com/)');

        // Alternatively, lie, and pretend to be a browser
        // curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)');

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

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