PHP (typically) generates HTML output for a web-site.
PHP（通常）为网站生成 HTML 输出。
When displaying HTML, the browser (typically) collapses all whitespace in text into a single space. Sometimes, between tags, it even collapses whitespace to nothing.
显示 HTML 时，浏览器（通常）会将文本中的所有空格折叠为一个空格。有时，在标签之间，它甚至会将空白折叠为空。
In order to persuade the browser to display whitespace, you need to include special tags like or <br/>in your HTML to add non-breaking whitespace or new lines, respectively.
为了说服浏览器显示空格，您需要在 HTML 中包含像 或 之类的特殊标签<br/>，以分别添加不间断的空格或新行。

To render more than one whitespace on most web browsers use instead of normal white spaces.
要在大多数 Web 浏览器上呈现多个空格，请使用 代替普通空格。
echo "<p>Hello punt"; // This will render as Hello Punt (with 4 white spaces)
echo "<p> Hello punt"; // This will render as Hello punt (with one space)
For showing data in raw format (with exact number of spaces and "enters") use HTML <pre>tag.
要以原始格式显示数据（具有确切数量的空格和“输入”），请使用 HTML<pre>标记。
echo "<pre>Hello punt</pre>"; //Will render exactly as written here (8 white spaces)
Or you can use some CSS to style current block, not to break text or strip spaces (dunno bout this one)
或者你可以使用一些 CSS 来设置当前块的样式，而不是破坏文本或去除空格（不知道这个）
Any way you do the output will be the same but the browser itself strips double white spaces and renders as one.
输出的任何方式都是相同的，但浏览器本身会去除双空格并呈现为一个。

pre is your friend.
pre 是你的朋友。
<pre>
<?php // code goes here
?>
</pre>
Or you can "View Source" in your browser. (Ctrl+U for most browser.)
或者您可以在浏览器中“查看源代码”。（对于大多数浏览器，Ctrl+U。）

is this for display purposes? if so you really should consider separating your display form your logic and use style sheets for formatting. being server side php should really allow providing and accepting data. while you could surely use php to do what you are asking I am a very firm believer in keeping display and logic with as much separation as possible. with styles you can do all of your typesetting.
这是用于展示目的吗？如果是这样，您真的应该考虑将显示与逻辑分开并使用样式表进行格式化。作为服务器端 php 应该真正允许提供和接受数据。虽然您肯定可以使用 php 来完成您所要求的操作，但我坚信尽可能多地分离显示和逻辑。使用样式，您可以进行所有排版。
give output class wrappers and style accordingly.
相应地给出输出类包装器和样式。
