HomeBackend DevelopmentPHP TutorialEmail Sending API Interface Guide in PHP

With the popularity of email in our daily lives, email sending has become an essential function in many applications. As a popular web development language, PHP also provides a corresponding email sending API interface.

This article will introduce the email sending API interface in PHP to beginners and developers, including how to configure the mail server, how to use PHP's built-in email functions, and how to use a third-party email sending library.

1. Configure the mail server

Before using PHP to send emails, you need to first configure an SMTP server. SMTP (Simple Mail Transfer Protocol) is a protocol used to send emails on the Internet. The SMTP server can be your own server or a free or paid SMTP service provided by a third party.

Before configuring the SMTP server, you need to determine the following information: the domain name or IP address of the SMTP server, the SMTP port number, the user name and password of the SMTP server, and the encryption method (if required).

1. Use PHP built-in functions to send emails

PHP has multiple built-in functions for sending emails. The most commonly used function is the mail() function. The syntax of the mail() function is as follows:

mail(to, subject, message, headers, parameters)

where, to represents the email address of the recipient; subject represents the subject of the email; message represents the email content; headers represents the email header, used to specify attachments, CC emails, etc.; parameters are optional and used to pass additional parameters, such as the SMTP server address.

The following is an example of using the mail() function to send an email:

$to = "receiver@example.com";
$subject = " Test Mail";
$message = "This is a test email.";
$headers = "From: sender@example.com
";
$headers .= "Content-type: text/html
";
if(mail($to, $subject, $message, $headers)){

echo "Email sent successfully";

}else{

echo "Email sending failed";

}
?>

The above code will send the message to the recipient address via email on the specified SMTP server. Please make sure the mail server is configured correctly and the SMTP settings in the php.ini file are correct.

2. Use a third-party email sending library

PHPMailer is a popular third-party email sending library. It is more flexible and reliable than PHP's built-in mail() function, and provides more features and options.

To use PHPMailer to send mail to an SMTP server, you need to install it first and include it in your PHP code via an include statement. Here is an example:

require 'phpmailer/PHPMailerAutoload.php';

$mail = new PHPMailer;

$mail->isSMTP(); // Settings Send email using SMTP protocol
$mail->Host = 'smtp.gmail.com'; // Set SMTP server address
$mail->SMTPAuth = true; // Enable SMTP authentication
$ mail->Username = 'your-email@gmail.com'; // SMTP account name
$mail->Password = 'your-email-password'; // SMTP account password
$mail- >SMTPSecure = 'ssl'; // Enable SSL encryption, TLS is also available
$mail->Port = 465; // SMTP server port number
$mail->setFrom('your-email@ gmail.com', 'Your Name'); // Set the sender address and name
$mail->addAddress('recipient@example.com', 'Recipient Name'); // Add the recipient Address and name
$mail->Subject = 'Test Mail'; // Set the email subject
$mail->Body = 'This is a test email.'; // Set the email body

if(!$mail->send()) {

echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;

} else {

echo 'Message sent successfully';

}

The above code uses SMTP on gmail.com The server sends the email. Please note that because SMTP authentication requires that if you are using a Google SMTP server, you need to enable "Less Secure Application Access" first.

3. Summary

This article introduces how to use built-in functions and third-party email sending libraries to send emails in PHP.
