我在mail（）上遇到了问题。我试图制作 html 电子邮件发送，但随后我的网站无法正常工作。
代码：
$tresc = '<head>

<style type="text/css" media="screen">

td[class=resp-full-td] {width: 100%!important; clear: both;}
img[class="email-penrose-img-header"] {width:100% !important; max-width: 340px !important;}
}

请帮助我！当我得到这个时，网站无法正常工作（内部 500）。我做错了什么？"tresc"一词的意思是"文本"
在Kliknij na przycisk '<b>Aktywuj Konto</b>' poniżej.</span>中，您失去了字符串连续性'您应该改用''。您应该替换消息正文中'的所有出现''。
试试这个方式。我已经解决了此代码的问题。来源于w3schools
