This article mainly introduces various methods of sending emails in PHP, including using the mail() function, using pipes, using the phpmailer class, etc. Please refer to it for reference
1. Use mail() function There’s nothing much to say, just use the system’s built-in SMTP system to send, usually sendmail. This depends on each system. Use the reference manual. 2. Use the form of pipeline I just successfully tested it yesterday and used local qmail to send emails. The code is as follows: /* Use qmail to send mail function */ function send_check_mail($email, $subject,$uid,$buffer) { $command = "/var/qmail/bin/qmail-inject ".$email; //qmail program address, $email is the address to be sent. $handle = popen($command, "w"); //Open the pipe http://www.cnblogs.com/roucheng/ if (!$handle) { return false; } $from = "webmaster@unixsky.net"; //Sender fwrite($handle, "From: ".$from."＼n"); //Write data to the pipe fwrite($handle, "Return-Path: ".$from."＼n"); fwrite($handle, "To: ".$uid."＼n"); fwrite($handle, "Subject: ".$subject."＼n"); fwrite($handle, "Mime-Version: 1.0＼n"); fwrite($handle, "Content-Type: text/html; charset=＼"gb2312＼"＼n＼n"); fwrite($handle, $buffer."＼n"); pclose($handle); //Close the pipe return true; } ------------------Test sending email: //Send email $subject = "Test Email"; $uid = $_POST['uid']; //from information $content = "".$u_email ."Hello!Thank you, this email is for testing!
Please check your email: ".$u_email."
< ;br>". $close; } else { echo "Unfortunately, sending the voting email to your mailbox failed. Please try again or contact the development staff.
". $close; } Of course, you can also use the same method to handle the sendmail process to send emails. Code example below: The code is as follows: In fact, this pipeline method is relatively low-level and depends on the stability of the program you call. So it is an optional way to send emails. 3. Use phpmailer class It is an open source email class. Main site: http://phpmailer.sourceforge.net There are two files inside, one is class.smtp.php, and the other is class.phpmailer.php In addition, how to use the official website: Examples using phpmailer 1. Advanced ExampleThis demonstrates sending out multiple email messages with binary attachments from a MySQL database with multipart/alternative support. The code is as follows: require("class.phpmailer.php"); $mail = new phpmailer(); $mail->From = "list@example.com"; $mail->FromName = "List manager"; $mail->Host = "smtp1.example.com;smtp2.example.com"; $mail->Mailer = "smtp"; @MYSQL_CONNECT("localhost","root","password"); @mysql_select_db("my_company"); $query?=?SELECT full_name, email,?hoto?ROM employee?HERE?d=$id"; $result??MYSQL_QUERY($query); while ($row = mysql_fetch_array ($result)) { // HTML body $body = "Hello " . $row["full_name"] . ",
"; $body .= "Your personal photograph to this message.
";
$body .= "Sincerely,
";
$body .= "phpmailer List manager";
// Plain text body (for mail clients that cannot read HTML)
$text_body = "Hello " . $row["full_name"] . ", ＼n＼n";
$text_body .= "Your personal photograph to this message.＼n＼n";
$text_body .= "Sincerely, ＼n";
$text_body .= "phpmailer List manager";
$mail->Body = $body;
$mail->AltBody = $text_body;
$mail->AddAddress($row["email"], $row["full_name"]);
$mail->AddStringAttachment($row["photo"], "YourPhoto.jpg");
if(!$mail->Send())
echo "There has been a mail error sending to " . $row["email"] . "
";
// Clear all addresses and attachments for next loop
$mail->ClearAddresses();
$mail->ClearAttachments();
}
2. Extending phpmailerExtending classes with inheritance is one of the most powerful features of object-oriented programming. It allows you to make changes to the original class for your own personal use without hacking the original classes. Plus, it is very easy to do. I've provided an example:
Here's a class that extends the phpmailer class and sets the defaults for the particular site:
PHP include file: mail.inc.php
The code is as follows:
require("class.phpmailer.php");
The code is as follows:
class my_phpmailer extends phpmailer {
// Set default variables for all new objects
var $From = "from@example.com";
var $FromName = "Mailer";
var $Host = "smtp1.example.com;smtp2.example.com";
var $Mailer = "smtp"; var $Mailer = "smtp";
var $WordWrap = 75;
// Replace the default error_handler
function error_handler($msg) {
print("My Site Error");
print("Description:");
printf("%s", $msg);
exit;
} }
// Create an additional function
function do_something($something) {
// Place your new code here
} }
}
Now here's a normal PHP page in the site, which will have all the defaults set above:
Normal PHP file: mail_test.php
The code is as follows:
require("mail.inc.php");
// Instantiate your new class
$mail = new my_phpmailer;
// Now you only need to add the necessary stuff
$mail->AddAddress("josh@example.com", "Josh Adams");
$mail->Subject = "Here is the subject";
$mail->Body = "This is the message body";
$mail->AddAttachment("c:/temp/11-10-00.zip", "new_name.zip"); // optional name
if(!$mail->Send())
{
echo "There was an error sending the message";
exit;
}
echo "Message was sent successfully";
4. Use PEAR::Net_SMTP component
PEAR is really a good thing, and many people may not use it very much. At least I currently use its DB class, which is good for sending emails.
If you need the Net_SMTP class, you can go to http://pear.php.net to download it. The user manual of the Net_SMTP class:
http://pear.php.net/manual/en/package.networking.net-smtp.php
I use the above classes, this one is the best, whether it is speed or anything else, but the operation involves some simple SMTP protocols.
My usage code:
The code is as follows:
//---------------------------------------------
require_once 'Net/SMTP.php'; //Load class library
$subject = "Test Email";
$uid = $_POST['uid']; //from information
$content = "
Thank you, this email is for testing!
