php发送邮件 支持多种方式

 

 <?php
//发送电子邮件
/**
$email_to = '[email protected],[email protected]';//email地址,多个地址用,分隔开
$email_subject = '邮件标题';//email标题
$email_message = '邮件内容';//邮件内容
$charset = 'UTF-8';//邮件编码
$mailconf = array(
'mailsend'=>'2',
'mailserver'=>'smtp.126.com',
'mailport'=>'25',
'mailauth'=>'1',
'mailfrom'=>'sjf122 <[email protected]>',
'mailauth_username'=>'[email protected]',
'mailauth_password'=>'******',
'maildelimiter'=>'0',
'mailsilent'=>'0',
);
sharpng_sendmail($email_to, $email_subject, $email_message, $charset, $mailconf);
*/
function sharpng_sendmail($email_to, $email_subject, $email_message, $charset, $mailconf){
/**
* 必须参数
* ++++++++++++++++++++
* 收信人地址
* $email_to 例如[email protected]
* 邮件标题
* $email_subject 例如 祝贺您称为sharpng的客户
* 邮件内容
* $email_message 例如 sharpng是最好的wap建站程序之一,在您的帮助下,sharpng将会更好的成长
* 发送方式(三选一)
* $mailsend=1 通过 PHP 函数的 sendmail 发送(推荐此方式)
* $mailsend=2 通过 SOCKET 连接 SMTP 服务器发送(支持 ESMTP 验证)
* $mailsend=3 通过 PHP 函数 SMTP 发送 Email(仅 Windows 主机下有效, 不支持 ESMTP 验证)
* 邮件头的分隔符,请根据您邮件服务器的设置调整此参数(三选一)
* $maildelimiter=0 使用 LF 作为分隔符(通常为 Unix/Linux 主机)
* $maildelimiter=1 使用 CRLF 作为分隔符(通常为 Windows 主机)
* $maildelimiter=2 使用 CR 作为分隔符(通常为 Mac 主机)
* 屏蔽邮件发送中的全部错误提示(二选一)
* $mailsilent=1 是
* $mailsilent=0否
* ++++++++++++++++++++
* 下面的 参数根据$mailsend参数的值选择性输入
* ----------
* 假如$mailsend=2/3
* $mailserver SMTP 服务器,例如smtp.126.com
* $mailport SMTP 端口 默认为 25,例如25
* ----------
* 假如$mailsend=2
* $mailauth=1 是/$mailauth=0 否 - 要求身份验证,如果 SMTP 服务器要求身份验证才可以发信，请选择“是”(二选一)
* $mailfrom 发信人邮件地址 如果需要验证, 必须为本服务器的邮件地址。邮件地址中如果要包含用户名，格式为“username <[email protected]>”，也可以只填地址,例如 [email protected]
* $mailauth_username SMTP 身份验证用户名，如126邮箱的是[email protected]
* $mailauth_password SMTP 身份验证密码
* ----------
