前言：
今天我们对“php发送邮件”可能比较看重，同学们都需要学习一些“php发送邮件”的相关内容。那么小编同时在网络上网罗了一些有关“php发送邮件””的相关知识，希望各位老铁们能喜欢，咱们快快来了解一下吧！必须在php.ini文件中正确配置PHP ，并详细说明系统如何发送电子邮件。打开/ etc /目录中的php.ini文件，并找到标题为[邮件功能]的部分。
Windows用户应确保提供了两个指令。第一个称为SMTP，它定义您的电子邮件服务器地址。第二个称为sendmail_from，它定义您自己的电子邮件地址。
Windows的配置应如下所示：
[mail function]; For Win32 only.SMTP = smtp.secureserver.net; For win32 onlysendmail_from = webmaster@tutorialspoint.com
Linux用户只需要让PHP知道他们sendmail应用程序的位置即可。路径和任何所需的开关应指定给sendmail_path指令。
Linux的配置应该看起来像这样-
[mail function]; For Win32 only.SMTP = ; For win32 onlysendmail_from = ; For Unix onlysendmail_path = /usr/sbin/sendmail -t -i
现在您可以开始了-
发送纯文本电子邮件
PHP利用mail（）函数发送电子邮件。此功能需要三个必填参数，用于指定收件人的电子邮件地址，邮件主题和实际邮件，此外还有其他两个可选参数。
mail( to, subject, message, headers, parameters );
这是每个参数的说明。
一旦调用了邮件功能，PHP将尝试发送电子邮件，如果成功，它将返回true；如果失败，则将返回false。
可以将多个收件人指定为逗号分隔列表中mail（）函数的第一个参数。
发送HTML电子邮件
当您使用PHP发送文本消息时，所有内容将被视为简单文本。即使您将HTML标签包含在文本消息中，它也将显示为简单文本，并且不会根据HTML语法设置HTML标签的格式。但是PHP提供了将HTML消息作为实际HTML消息发送的选项。
发送电子邮件时，您可以指定Mime版本，内容类型和字符集来发送HTML电子邮件。
例
以下示例将HTML电子邮件发送到xyz@somedomain.com，并将其复制到afgh@somedomain.com。您可以使用以下方式对程序进行编码：它应接收用户的所有内容，然后发送电子邮件。
<html> <head> <title>Sending HTML email using PHP</title> </head> <body> <?php $to = "xyz@somedomain.com"; $subject = "This is subject"; $message = "<b>This is HTML message.</b>"; $message .= "<h1>This is headline.</h1>"; $header = "From:abc@somedomain.com \r\n"; $header .= "Cc:afgh@somedomain.com \r\n"; $header .= "MIME-Version: 1.0\r\n"; $header .= "Content-type: text/html\r\n"; $retval = mail ($to,$subject,$message,$header); if( $retval == true ) { echo "Message sent successfully..."; }else { echo "Message could not be sent..."; } ?> </body></html>通过电子邮件发送附件要发送包含混合内容的电子邮件，需要将Content-type标头设置为multipart / mixed。然后可以在边界内指定文本和附件节。
边界以两个连字符开头，后跟一个唯一的数字，该数字不能出现在电子邮件的消息部分。PHP函数md5（）用于创建32位十六进制数字以创建唯一数字。表示电子邮件最后部分的最后边界也必须以两个连字符结尾。
<?php // request variables // important $from = $_REQUEST["from"]; $emaila = $_REQUEST["emaila"]; $filea = $_REQUEST["filea"]; if ($filea) { function mail_attachment ($from , $to, $subject, $message, $attachment){ $fileatt = $attachment; // Path to the file $fileatt_type = "application/octet-stream"; // File Type $start = strrpos($attachment, '/') == -1 ? strrpos($attachment, '//') : strrpos($attachment, '/')+1; $fileatt_name = substr($attachment, $start, strlen($attachment)); // Filename that will be used for the file as the attachment $email_from = $from; // Who the email is from $subject = "New Attachment Message"; $email_subject = $subject; // The Subject of the email $email_txt = $message; // Message that the email has in it $email_to = $to; // Who the email is to $headers = "From: ".$email_from; $file = fopen($fileatt,'rb'); $data = fread($file,filesize($fileatt)); fclose($file); $msg_txt="\n\n You have recieved a new attachment message from $from"; $semi_rand = md5(time()); $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; $headers .= "\nMIME-Version: 1.0\n" . "Content-Type: multipart/mixed;\n" . " boundary=\"{$mime_boundary}\""; $email_txt .= $msg_txt; $email_message .= "This is a multi-part message in MIME format.\n\n" . "--{$mime_boundary}\n" . "Content-Type:text/html; charset = \"iso-8859-1\"\n" . "Content-Transfer-Encoding: 7bit\n\n" . $email_txt . "\n\n"; $data = chunk_split(base64_encode($data)); $email_message .= "--{$mime_boundary}\n" . "Content-Type: {$fileatt_type};\n" . " name = \"{$fileatt_name}\"\n" . //"Content-Disposition: attachment;\n" . //" filename = \"{$fileatt_name}\"\n" . "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n" . "--{$mime_boundary}--\n"; $ok = mail($email_to, $email_subject, $email_message, $headers); if($ok) { echo "File Sent Successfully."; unlink($attachment); // delete a file after attachment sent. }else { die("Sorry but the email could not be sent. Please go back and try again!"); } } move_uploaded_file($_FILES["filea"]["tmp_name"], 'temp/'.basename($_FILES['filea']['name'])); mail_attachment("$from", "youremailaddress@gmail.com", "subject", "message", ("temp/".$_FILES["filea"]["name"])); }?><html> <head> <script language = "javascript" type = "text/javascript"> function CheckData45() { with(document.filepost) { if(filea.value ! = "") { document.getElementById('one').innerText = "Attaching File ...
