有没有更好的方法来用PHP编写HTML字符串? [英] Is there a better way to write HTML strings in PHP?

问题描述

我发现自己在PHP中编写了很多返回HTML代码的函数.他们可能看起来像这样:

I find myself writing a lot of functions in PHP that return HTML code. They may look something like this:

function html_site_head()
{
    return
        "
            <div id=\"site_header\">
                <div id=\"site_header_inner\">
                    <div id=\"site_header_logo\"></div>

                    <div id=\"site_header_countdown\">BARE XX DAGER IGJEN</div>
                </div>
            </div>
        ";
}

现在我可以发誓，我已经看到了更好的方法来用PHP编写长字符串.我喜欢python的方式:

Now I can swear I've seen better ways to write long strings in PHP. I like python's way of doing it:

return """
    <div id="site_header">
        <div id="site_header_inner">
            <div id="site_header_logo"></div>

            <div id="site_header_countdown">BARE XX DAGER IGJEN</div>
        </div>
    </div>
"""

因为您不必转义引号.一种替代方法是使用单引号，但这意味着不直接在字符串中使用PHP变量.我发誓我已经在PHP中看到过类似的内容:

As you don't have to escape quotation marks. An alternative is using single quotation marks, but that means no using PHP variables directly in the string. I swear I've seen something like this in PHP:

return <<<
    <div id="site_header">
        <div id="site_header_inner">
            <div id="site_header_logo"></div>

            <div id="site_header_countdown">BARE XX DAGER IGJEN</div>
        </div>
    </div>

或类似的东西.有人可以刷新我的记忆吗?

Or something similar. Could someone refresh my memory on this?

谢谢

推荐答案

PHP知道几种声明的语法字符串:

• 单引号

' … '

双引号

" … "

heredoc语法

<<<DELIMITER
 …
DELIMITER

nowdoc语法(自PHP 5.3.0起)

nowdoc syntax (since PHP 5.3.0)

<<<'DELIMITER'
 …
DELIMITER

因此，您本身不必使用双引号.

So you don’t have to use the double quotes per se.
