如何使用模板或动态内容进行php电子邮件发送

PHPMailer也是发送电子邮件和mail（）函数的好选择，但问题是为电子邮件正文生成动态内容，并且主题不是最好的。

例如我创建了一个带有正文模板的php文件或一个具有相同功能的类，但是很难维护。

您对组织该代码有何建议？

有没有办法创建电子邮件模板？ （像树枝）。 你如何组织文件夹和文件？ 那有什么文件推荐吗？ 谢谢你的帮助

与您在PHP中已经用于生成动态HTML的内容没有什么不同。除了不是通过您的Web服务器将生成的HTML输出发送到客户端UA，您将通过MTA将其发送到电子邮件UA。

20年前，有人想要创造一个好的模板引擎来生成动态内容（它被称为PHP）。事实证明它今天仍然非常有用。

假设您的电子邮件中有一个类似于此的模板文件。

<table>
    <?php foreach($rows as $row) { ?>
    <tr>
        <?php foreach($row as $column) { ?>
        <td><?=$column?></td>
        <?php } ?>
    </tr>
    <?php } ?>
</table>

假设有一些模板系统可以将这些模板渲染成这样的东西。

class Template {
    protected $templateFile = "";
    protected $templateVars = [];
    public function __construct($templateFile, Array $templateVars= []) {
        $this->templateVars = $templateVars;
        $this->templateFile = $templateFile;
    }
    public function __toString() {
        export($this->templateVars, EXTR_SKIP);
        ob_start();
        include $this->templateFile;
        return ob_get_clean();
    }
}

现在，您可以进一步扩展这个非常简单的模板抽象，以包含诸如电子邮件主题行，发件人电子邮件地址等内容...... 

class SendEmail {
    public function __construct($to, $subject, $template, Array $data) {
        $template = new Template($file, $data); // create the email template
        $this->emailBody = (string) $template; // generate the content
        $this->to = $to;
        $this->subject = $subject;
    }
    public function send() {
        // Send email using PHP mailer or whatever here
    }
}
