PHP获取网页内容 [英] PHP Get contents of webpage

问题描述

因此，我正在使用 PHP简单HTML DOM解析器来获取网页的内容.知道自己在做的事是对的之后，我仍然得到一个错误，那就是找不到任何东西.

So I am using the PHP Simple HTML DOM Parser to get the contents of a webpage. After I knew what I was doing was right, I still got the error that there was nothing to be found.

所以这是我用来查看是否有任何实际被捕获的东西:

So here's what I am using to see if there is anything actually being caught:

<?php
include_once('simple_html_dom.php');

error_reporting(E_ALL);
ini_set('display_errors', '1');

$first_url = "http://www.transfermarkt.co.uk/en/chinese-super-league/startseite/wettbewerb_CSL.html"; // works

$html = file_get_html($first_url);
echo "<textarea>Output\n===========\n $html</textarea><br /><br />";

$second_url = "http://www.transfermarkt.co.uk/en/chinese-super-league/torschuetzen/wettbewerb_CSL.html"; // does not work?

$html = file_get_html($second_url);
echo "<textarea>Output\n===========\n $html</textarea><br />";
?>

没有错误.在第二个文本区域中没有任何内容.第二个网址似乎没有被该工具刮掉……为什么?

No errors. Nothing in the 2nd textarea. The second URL does not seem to be getting scraped bt the tool... why?

推荐答案

simple_php_dom.php包含:

define('MAX_FILE_SIZE', 600000);
...
if (empty($contents) || strlen($contents) > MAX_FILE_SIZE)
{
    return false;
}

第二页超过672000字节，因此此大小检查失败.增大该常数，您就可以了.

The second page is over 672000 bytes, so this size check fails. Increase that constant and you should be OK.
