PHP简单HTML DOM解析器在有效url上返回false [英] PHP Simple HTML DOM Parser returning false on valid url

问题描述

我正在尝试以下操作:

$url = 'https://www.tripadvisor.es/Hotels-g187514-Madrid-Hotels.html'

$ta_html = file_get_html($url);
var_dump($ta_html);

它返回false，这可以正常工作并正确获取html的

it returns false, this is working and correctly getting the html for:

$url = 'https://www.tripadvisor.es/Hotels-g294316-Lima_Lima_Region-Hotels.html#ACCOM_OVERVIEW'

我首先想到的是它具有重定向功能，但是我用curl及其200 ok检查了页眉，在两种情况下看起来都一样.会发生什么事?该如何解决?

My first thought was that it had a redirect but I checked the headers with curl and its 200 ok and it seemed like the same on both cases. What can be happening? how it can be solved?

这似乎是此问题的重复: 返回错误的简单HTML DOM ，也未得到答复

This seems to be a duplicate of this problem: Simple HTML DOM returning false that is also unanswered

推荐答案

似乎HTML DOM解析器失败，因为HTML文件大小大于库的最大文件大小.当您调用file_get_html()时，它会根据其MAX_FILE_SIZE常量进行文件大小检查.因此，在调用任何HTML DOM解析器方法之前，请通过调用以下命令增加库使用的最大文件大小:

It looks like HTML DOM parser is failing because the HTML file size is greater than the library's max file size. When you call file_get_html() it does a file size check based on it's MAX_FILE_SIZE constant. So before calling any HTML DOM parser methods, increase the max file size used by the library by calling:

define('MAX_FILE_SIZE', 1200000); // or larger if needed, default is 600000

您也发现，您可以执行此操作来解决文件大小检查问题

Also as as you found out you can work around the file size check with doing this

$html = new simple_html_dom();
$html->load($str);
