php如何发邮件
PHP示例演示发送邮件给某个邮箱首先，建立一个index.html文件，代码如下：
|
|
<html><head><title>simple send mail </title></head><body><h1>mail form</h1><form name="form1" method="post" action="mail.php"><table><tr><td><b>to</b></td><td><input type="text" name="mailto" size="35"></td></tr><tr><td><b>subject</b></td><td><input type="text" name="mailsubject" size="35"></td></tr><tr><td><b>message</b></td><td><textarea name="mailbody" cols="50" rows="7"></textarea></td></tr><tr><td colspan="2"><input type="submit" name="submit" value="send"></td></tr></table></form></body></html> |
然后新建一个“mail.php”文档把传输的文档进行发送
|
|
<?php $stm="邮件内容"; require("smtp.php"); ########################################## $smtpserver = "smtp.qq.com";//smtp服务器 $smtpserverport = "465";//smtp服务器端口 $smtpusermail = "xxx@qq.com";//smtp服务器的用户邮箱 $smtpemailto = "aaa@qq.com";//发送给谁 $smtpuser = "xxx@qq.com";//smtp服务器的用户帐号 $smtppass = "666";//smtp服务器的用户密码 $mailsubject = "666 ";//邮件主题 $mailbody = $stm;//邮件内容 $mailtype = "html";//邮件格式（html/txt）,txt为文本邮件 ########################################## $smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);//这里面的一个true是表示使用身份验证,否则不使用身份验证. $smtp->debug = true;//是否显示发送的调试信息 $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype); echo "<script>alert('邮件发送成功');parent.document.adduser.cheheh.click();</script>"; exit; } ?> |
最后编写一个邮件类“smtp.php”

<?php class smtp { /* public variables */var $smtp_port; var $time_out; var $host_name; var $log_file; var $relay_host; var $debug; var $auth; var $user; var $pass; /* private variables */var $sock; /* constractor */function smtp($relay_host = "", $smtp_port = 25,$auth = false,$user,$pass) { $this->debug = false; $this->smtp_port = $smtp_port; $this->relay_host = $relay_host; $this->time_out = 30; //is used in fsockopen() $this->auth = $auth;//auth $this->user = $user; $this->pass = $pass; $this->host_name = "localhost"; //is used in helo command $this->log_file = ""; $this->sock = false; } /* main function */function sendmail($to, $from, $subject = "", $body = "", $mailtype, $cc = "", $bcc = "", $additional_headers = "") { $mail_from = $this->get_address($this->strip_comment($from)); $body = ereg_replace("(^|(\r\n))(\.)", "\1.\3", $body); $header .= "mime-version:1.0\r\n"; if($mailtype=="html") { $header .= "content-type:text/html\r\n"; } $header .= "to: ".$to."\r\n"; if ($cc != "") { $header .= "cc: ".$cc."\r\n"; } $header .= "from: $from<".$from.">\r\n"; $header .= "subject: ".$subject."\r\n"; $header .= $additional_headers; $header .= "date: ".date("r")."\r\n"; $header .= "x-mailer:by redhat (php/".phpversion().")\r\n"; list($msec, $sec) = explode(" ", microtime()); $header .= "message-id: <".date("ymdhis", $sec).".".($msec*1000000).".".$mail_from.">\r\n"; $to = explode(",", $this->strip_comment($to)); if ($cc != "") { $to = array_merge($to, explode(",", $this->strip_comment($cc))); } if ($bcc != "") { $to = array_merge($to, explode(",", $this->strip_comment($bcc))); } $sent = true; foreach ($to as $rcpt_to) { $rcpt_to = $this->get_address($rcpt_to); if (!$this->smtp_sockopen($rcpt_to)) { $this->log_write("error: cannot send email to ".$rcpt_to."\n"); $sent = false; continue; } if ($this->smtp_send($this->host_name, $mail_from, $rcpt_to, $header, $body)) { $this->log_write("e-mail has been sent to <".$rcpt_to.">\n"); } else{ $this->log_write("error: cannot send email to <".$rcpt_to.">\n"); $sent = false; } fclose($this->sock); $this->log_write("disconnected from remote host\n"); } return $sent; } /* private functions */function smtp_send($helo, $from, $to, $header, $body = "") { if (!$this->smtp_putcmd("helo", $helo)) { return $this->smtp_error("sending helo command"); } #auth if($this->auth) { if (!$this->smtp_putcmd("auth login", base64_encode($this->user))) { return $this->smtp_error("sending helo command"); } if (!$this->smtp_putcmd("", base64_encode($this->pass))) { return $this->smtp_error("sending helo command"); } } if (!$this->smtp_putcmd("mail", "from:<".$from.">")) { return $this->smtp_error("sending mail from command"); } if (!$this->smtp_putcmd("rcpt", "to:<".$to.">")) { return $this->smtp_error("sending rcpt to command"); } if (!$this->smtp_putcmd("data")) { return $this->smtp_error("sending data command"); } if (!$this->smtp_message($header, $body)) { return $this->smtp_error("sending message"); } if (!$this->smtp_eom()) { return $this->smtp_error("sending <cr><lf>.<cr><lf> [eom]"); } if (!$this->smtp_putcmd("quit")) { return $this->smtp_error("sending quit command"); } return true; } function smtp_sockopen($address) { if ($this->relay_host == "") { return $this->smtp_sockopen_mx($address); } else{ return $this->smtp_sockopen_relay(); } } function smtp_sockopen_relay() { $this->log_write("trying to ".$this->relay_host.":".$this->smtp_port."\n"); $this->sock = @fsockopen($this->relay_host, $this->smtp_port, $errno, $errstr, $this->time_out); if (!($this->sock && $this->smtp_ok())) { $this->log_write("error: cannot connenct to relay host ".$this->relay_host."\n"); $this->log_write("error: ".$errstr."
