定义和用法

mail() 函数允许您从脚本中直接发送电子邮件。

如果邮件的投递被成功地接收，则返回 true，否则返回 false。

语法

mail(to,subject,message,headers,parameters)

参数

描述

to

必需。规定邮件的接收者。

subject

必需。规定邮件的主题。该参数不能包含任何换行字符。

message

必需。规定要发送的消息。

headers

必需。规定额外的报头，比如 From,Cc 以及 Bcc。

parameters

必需。规定 sendmail 程序的额外参数。

说明

在 message 参数规定的消息中，行之间必须以一个 LF（n）分隔。每行不能超过 70 个字符。 （Windows 下）当 PHP 直接连接到 SMTP 服务器时，如果在一行开头发现一个句号，则会被删掉。要避免此问题，将单个句号替换成两个句号。

$text = str_replace("n.","n..",$text);
