grammar
mail(to,subject,message,headers,parameters)
| 参数 | 描述 |
|---|---|
| to | 必需。规定电子邮件的接收者。 |
| subject | 必需。规定电子邮件的主题。注释：该参数不能包含任何换行字符。 |
| message | 必需。定义要发送的消息。用 LF（\n）将每一行分开。行不应超过70个字符。
Windows 注释：当 PHP 直接连接到 SMTP 服务器时，如果在消息的某行开头发现一个句号，则会被删掉。要解决这个问题，请将单个句号替换成两个句号： |
| headers | 可选。规定额外的报头，比如 From、Cc 和 Bcc。附加标头应该用 CRLF（\r\n）分开。
注释：发送电子邮件时，它必须包含一个 From 标头。可通过该参数进行设置或在 php.ini 文件中进行设置。 |
| parameters | 可选。规定 sendmail 程序的额外参数（在 sendmail_path 配置设置中定义）。例如：当 sendmail 和 -f sendmail 的选项一起使用时，sendmail 可用于设置发件人地址。 |
Tips and Notes
Note: You need to remember that e-mail delivery is accepted, does not mean that e-mail arrives at the destination program.

<?php
$txt = "First line of textnSecond line of text";
// Use wordwrap() if lines are longer than 70 characters
$txt = wordwrap($txt,70);
// Send email
mail("[email protected]","My subject",$txt);
?>
$txt = "First line of textnSecond line of text";
// Use wordwrap() if lines are longer than 70 characters

mail("[email protected]","My subject",$txt);
?>

<?php
