如何在PHP's rawurlencode编码的mailto链接中添加换行符 - How to add a line break into a mailto link that is being encoded with PHP's rawurlencode

How to add a line break into a mailto link that is being encoded with PHP's rawurlencode

我有这样的东西

<a href='mailto:mike@example.com?subject=<?php print rawurlencode('This is the subject.');?>&body=<?php print rawurlencode('Line 1 of body. Line 2 of body.');?>'>Email</a>

我想在消息正文中加入一个换行符。我发现通过谷歌，你可以把%0D%0A到mailto做一个换行，但问题是，rawurlencode将编码它。我可以在rawurlencode中输入什么来使换行符显示在消息中

如果你使用双引号，你可以在字符串中添加'r'n字符，这将避免你所描述的双重编码问题。

<?php
echo rawurlencode("Line One.'r'nLine Two.");
/* Line%20One.%0D%0ALine%20Two. */

http_build_query函数可能也很方便。

<?php
$params = array(
    'subject'   => 'Subject',
    'body'      => "Line One.'r'nLine Two."
);
echo http_build_query($params);
/* subject=Subject&body=Line+One.%0D%0ALine+Two. */

'n -这叫做换行-特殊字符
