Php cron工作、生日检查和发送电子邮件（只是确保）

我已经创建了send_bday_email.php，它在客户生日前两周发送生日电子邮件

<?php

$today = date('Y-m-d');
$todayMD = date('m-d');

include_once "../../mysqli_connect.php";
$sql= mysqli_query($dbc, "SELECT * FROM Customer_Info");
$mail_body = '';

while ($row= mysqli_fetch_array($sql)) {
    $id = $row["id"];
    $email = $row["email"]; 

    $birthday = $row['birthday'];

    $bday = new DateTime($birthday);

    $bday->sub(new DateInterval('P14D'));

    $twoWeekbday = $bday->format('m-d');

    if ($todayMD==$twoWeekbday) {
        if(empty($row["firstName"])){

            $name = 'Customer';

        } else {
            $name = $row["firstName"];
        }

        $mail_body = file_get_contents('../forms/bday_email_form.html');
    }
}

我使用了todayMD，这样那年就不会中断我的（$todayMD==$twoWeekbday）代码。你可以在你的测试服务器上测试它……不要删除（）然后再问，这真是侮辱我删除我的帖子，因为问题很广泛。我在制作php文件后问了这个问题，只是为了和你们确认一下。如果这是侮辱。很抱歉。对社区和php来说是相当陌生的
