我正在考虑删除所有格式，所有文本，就像你去网站的任何页面一样，用户Ctrl+A和Ctrl+ C，然后使用Ctrl+ V将所有内容粘贴在记事本中。你会明白我说的提取所有文本....是什么意思。让我们用一个网站来更好地解释:这个网站:https://developer.palm.com/content/resources/develop/quick_start_ios.html

If you've been developing for iOS® and are looking to expand your audience, we're here to help. Getting started with webOS is easy! If your current focus is OpenGL/SDL, then the transition will be simplicity itself. We have lots of great stories of developers porting their OpenGL apps very quickly. You can use the publicly available 3.0 SDK to do OpenGL/SDL development now with the included Plug-in Development Kit (PDK). Best of all, the PDK integrates nicely with Xcode.
If your focus is web app development, you'll want to look at Enyo, our next-generation JavaScript framework, which is included in the 3.0 SDK.
Ready to get started?
Download the SDK
It's free! (While you're at it, sign up for the Developer Program.)
Try the Enyo tutorial or the OpenGL sample app
Choose the sample that's most appropriate for your skill set.

应该可以了
<?php
echo strip_tags(file_get_contents("https://developer.palm.com/content/resources/develop/quick_start_ios.html"));
这就是大意。您可以使用str_replace('<br/>', ''n', $output)来更好地格式化它。
我使用lynx，在您的终端上试试:
lynx -dump http://www.google.com
另一种方法是检索页面主体标签的值:
$html = new DOMDocument();
$html->loadHTMLFile("https://developer.palm.com/content/resources/develop/quick_start_ios.html");
$body = $html->getElementsByTagName("body");
$body = $body->item(0);
echo $body->nodeValue;
您可以使用文档树来做到这一点，只需保留所有文本节点并删除所有元素节点。
