How to use file_get_contents or file_get_html?
提问by pguardiario
I've read through quite a few questions on here and I'm not sure if I should be using file_get_contentsor file_get_htmlfor this.
我已经阅读了很多关于这里的问题，我不确定我是否应该使用file_get_contents或file_get_html为此使用。
All that I'm trying to do is use PHP to display the two tables from this page on my website: http://www.statmyweb.com/recently-analyzed/
我要做的就是使用 PHP 在我的网站上显示此页面上的两个表：http: //www.statmyweb.com/recently-analyzed/
I know how to get their full page and display it on my site of course, but I can't figure out how I'm able to just pull those two tables without also getting the header/footer.
我当然知道如何获取他们的完整页面并将其显示在我的网站上，但是我无法弄清楚如何在不获取页眉/页脚的情况下仅拉出这两个表。

You are not able to specify in file_get_contents()just to retrieve the tables.
您不能file_get_contents()仅指定 in来检索表。
You would have to get the return value of file_get_contents()using:
您必须获得使用的返回值file_get_contents()：
$result = file_get_contents("urlHere");
And then analyse the $resultvariable and extract what information you need to output.
然后对$result变量进行分析，提取出需要输出的信息。

You want file_get_htmlbecause file_get_contentswill load the response body into a string but file_get_htmlwill load it into simple-html-dom.
您想要file_get_html因为file_get_contents会将响应正文加载到字符串中，但file_get_html会将其加载到 simple-html-dom 中。
$dom = file_get_html($url);
$tables = $dom->find('table');
echo $tables[0];
echo $tables[1];
Alternatively you could use file_get_contentsalong with str_get_html:
或者，您可以file_get_contents与str_get_html以下一起使用：
$dom = str_get_html(file_get_contents($url));
But that would be silly.
但那将是愚蠢的。

Take the full website content by file_get_contents(), then apply preg_match on the content you have got with <table>and </table>. This will bring you all the contents under the table tags. While showing it in your web page, just put a <table>then echo your matched content and a </table>at the end.
通过 获取完整的网站内容file_get_contents()，然后将 preg_match 应用于您通过<table>和获得的内容</table>。这将为您带来表格标签下的所有内容。在您的网页中显示它时，只需将 a <table>then echo 您的匹配内容和 a</table>放在最后。
