How to Sending Mail in PHP: A Comprehensive Guide

Sending emails is a crucial aspect of web development and is used for a variety of purposes, including notifications, password resets, and marketing campaigns. In this article, we will explore the process of sending emails in PHP, covering all the necessary steps from start to finish.

Prerequisites Before we dive into the details of sending emails in PHP, you need to make sure that your server has the PHP Mail() function enabled. You can check this by creating a simple PHP script and running it on your server.

Sending Email with PHP Mail() Function The PHP Mail() function is the simplest and most commonly used method for sending emails in PHP. It works by sending an email to the specified recipient using the Simple Mail Transfer Protocol (SMTP). Here’s how to use the PHP Mail() function:

$to = "";
$subject = "Test Email";
$message = "This is a test email sent from PHP";
$headers = "From:";
mail($to, $subject, $message, $headers);

In this example, the recipient’s email address is specified in the $to variable, the subject of the email is specified in the $subject variable, and the message is specified in the $message variable. The $headers variable is used to specify the sender’s email address.

Using an SMTP Server If your server doesn’t have the PHP Mail() function enabled, you can use an SMTP server to send emails. To do this, you need to install a PHP library that supports SMTP, such as PHPMailer or SwiftMailer.

Here’s a simple example of how to send an email using PHPMailer:

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

$mail = new PHPMailer(true);

try {
    $mail->Host = '';
    $mail->SMTPAuth = true;
    $mail->Username = '';
    $mail->Password = 'your-email-password';
    $mail->SMTPSecure = 'none';
    $mail->Port = 587;

    $mail->setFrom('', 'Sender');
    $mail->addAddress('', 'Recipient');

    $mail->Subject = 'Test Email';
    $mail->Body = 'This is a test email sent from PHPMailer';

    echo 'Message has been sent';
} catch (Exception $e) {
    echo 'Message could not be sent. Mailer Error: ', $mail->ErrorInfo;

In this example, the PHPMailer library is used to send an email using the MigoSMTP server. You’ll need to replace and your-email-password with your actual email address and password.


What is PHP used for when it comes to sending mail?

PHP is a server-side scripting language that can be used to send emails. It can be integrated into a website to automate the process of sending emails, such as sending password resets or notification emails to users. PHP provides a set of built-in functions, such as the “mail()” function, that can be used to send emails from a web server.

Important Information:

PHP is a server-side scripting language.
PHP can be used to send emails.
PHP provides built-in functions for sending emails.

How does the PHP “mail()” function work?

The “mail()” function is the primary means of sending emails in PHP. It is a simple function that takes a number of parameters, such as the recipient’s email address, the subject of the email, and the message itself. The function then uses the web server’s built-in email capabilities to send the email.

The “mail()” function requires that the web server be properly configured to send email. This typically involves specifying an SMTP server and port, as well as any necessary authentication information.

Important Information:

The “mail()” function is used to send emails in PHP.
It requires the web server to be properly configured to send email.
The “mail()” function takes parameters like recipient’s email address, subject, and message.

What is SMTP and why is it important for sending emails in PHP?

SMTP (Simple Mail Transfer Protocol) is the standard protocol for sending emails on the internet. It is used by email servers to send and receive emails, and by email clients (such as Outlook or Gmail) to communicate with email servers.

When using PHP to send emails, it is necessary to specify an SMTP server and port to use for sending the email. The SMTP server is responsible for delivering the email to its intended recipient. The web server running PHP does not typically have built-in email capabilities, so it must rely on an SMTP server to do the actual sending of the email.

Important Information:

An SMTP server and port are required for sending emails with PHP.
The web server running PHP does not have built-in email capabilities.

What are some common issues when sending mail in PHP?

There are a number of common issues that can arise when sending emails with PHP. Some of these include:

Incorrect SMTP server configuration – If the SMTP server information is incorrect, the email may not be delivered.

Authentication failures – If the SMTP server requires authentication, it may reject the email if the authentication information provided by PHP is incorrect.

Spam filters – The email may be marked as spam by the recipient’s email server and never delivered.

Email size limitations – Some email servers have limits on the size of the emails that can be sent. If the email being sent with PHP exceeds this limit, it may not be delivered.

Delivery failures – For various reasons, the email may not be delivered to the recipient.
