LAST EDIT: after 7 years I'm still getting upvotes for this answer, but I guess this oneis now much more accurate.
最后一次编辑：7 年后，我仍然为这个答案投票，但我想这个答案现在更准确了。
Sure you can, but you'll need to render the page with something. If you really want to only use php, I suggest you HTMLTOPS, which renders the page and outputs it in a ps file (ghostscript), then, convert it in a .jpg, .png, .pdf.. can be little slower with complex pages (and don't support all the CSS).
当然可以，但是你需要用一些东西来渲染页面。如果您真的只想使用 php，我建议您使用HTMLTOPS，它会呈现页面并将其输出到 ps 文件（ghostscript）中，然后将其转换为 .jpg、.png、.pdf ..复杂的页面（并且不支持所有的 CSS）。
Else, you can use wkhtmltopdfto output a html page in pdf, jpg, whatever.. Accept CSS2.0, use the webkit (safari's wrapper) to render the page.. so should be fine. You have to install it on your server, as well..
否则，您可以使用wkhtmltopdf以 pdf、jpg 等格式输出 html 页面。接受 CSS2.0，使用 webkit（safari 的包装器）来呈现页面。所以应该没问题。您还必须将它安装在您的服务器上。
UPDATENow, with new HTML5 and JS feature, is also possible to render the page into a canvas object using JavaScript. Here a nice library to do that: Html2Canvasand here is an implementationby the same author to get a feedback like G+. Once you have rendered the dom into the canvas, you can then send to the server via ajax and save it as a jpg.
更新现在，借助新的 HTML5 和 JS 功能，还可以使用 JavaScript 将页面呈现到画布对象中。这是一个很好的库来做到这一点：Html2Canvas和这里是同一作者的一个实现，以获得像 G+ 这样的反馈。将 dom 渲染到画布中后，您可以通过 ajax 将其发送到服务器并将其保存为 jpg。
EDIT: You can use the imagemagick tool for transforming pdf to png. My version of wkhtmltopdf does not support images. E.g. convert html.pdf -append html.png.
编辑：您可以使用 imagemagick 工具将 pdf 转换为 png。我的 wkhtmltopdf 版本不支持图像。例如convert html.pdf -append html.png。
EDIT: This small shell scriptgives a simple / but working usage example on linux with php5-cli and the tools mentioned above.
编辑：这个小 shell 脚本在 linux 上使用 php5-cli 和上面提到的工具提供了一个简单/但有效的用法示例。
EDIT: i noticed now that the wkhtmltopdf team is working on another project: wkhtmltoimage, that gives you the jpg directly
编辑：我现在注意到 wkhtmltopdf 团队正在研究另一个项目：wkhtmltoimage，它直接为您提供 jpg

It's in Python, but going over the documentation and code you can see exactly how this is done. If you can run python, then it's a ready-made solution for you:
它是在 Python 中编写的，但是通过查看文档和代码，您可以确切地看到这是如何完成的。如果你可以运行python，那么它就是一个现成的解决方案：
Note that everything can run on one machine for one platform, or one machine with virtual machines running the other platforms.
请注意，一切都可以在一台机器上针对一个平台运行，或者在一台机器上运行其他平台的虚拟机。
