在电子邮件的主题中插入date+time

Question

如何在主题的开头插入日期和时间？

代码中的日期(‘d-m-Y h:m:s')不起作用，并返回此错误:解析错误:语法错误，意外的T_STRING

<?php
    mail('joe@example.com', '"date('d-m-Y h:m:s')" Daily Backup: example.com', 'Download your daily backup from this link: http://example.com/backups/backup.zip');
?>

这段代码可以工作：(不带日期和时间)

<?php
    mail('joe@example.com', 'Daily Backup: example.com', 'Download your daily backup from this link: http://example.com/backups/backup.zip');
?>

谢谢你的帮助！

Answer 1

您错过了将php代码封装在字符串中：

mail('joe@example.com', '"'.date('d-m-Y h:m:s').'" Daily Backup: example.com', 'Download your daily backup from this link: http://example.com/backups/backup.zip');

Answer 2

看起来像是语法错误。尝试将日期函数放在字符串开始之前，这样它就变成了

<?php
    mail('joe@example.com', date('d-m-Y h:m:s').' Daily Backup: example.com', 'Download your daily backup from this link: http://example.com/backups/backup.zip');
?>
