How to send attachment mail in php

To send an email with an attachment in PHP, you can use the mail() function or a PHP email library such as PHPMailer. Here's an example of how to do it using the mail() function:

<?php
// Define the email details
$to = '[email protected]';
$subject = 'Email with attachment';
$message = 'This is the email body';

// Define the attachment details
$attachment = 'path/to/attachment.txt';

// Define the email headers
$headers = 'From: [email protected]'. "\r\n".
           'Reply-To: [email protected]'. "\r\n".
           'MIME-Version: 1.0'. "\r\n".
           'Content-Type: multipart/mixed; boundary="This is the boundary string"';

// Define the email body
$body = "This is the email body\r\n\r\n";
$body.= "--This is the boundary string\r\n";
$body.= "Content-Type: text/plain\r\n\r\n";
$body.= $message. "\r\n\r\n";
$body.= "--This is the boundary string\r\n";
$body.= "Content-Type: application/octet-stream; name=\"". basename($attachment). "\"\r\n";
$body.= "Content-Disposition: attachment; filename=\"". basename($attachment). "\"\r\n\r\n";
$body.= file_get_contents($attachment);

// Send the email
mail($to, $subject, $headers, $body);
?>

In this example, the email body is defined as a multipart message with a text/plain part and an attachment part. The attachment part is defined using the Content-Type and Content-Disposition headers, and the attachment data is read using the file_get_contents() function.

Alternatively, you can use a PHP email library such as PHPMailer to send the email. Here's an example of how to do it using PHPMailer:

<?php
require_once 'PHPMailer/PHPMailer.php';
require_once 'PHPMailer/SMTP.php';

// Create a new PHPMailer instance
$mail = new PHPMailer\PHPMailer\PHPMailer();

// Set the email details
$mail->setFrom('[email protected]', 'Sender Name');
$mail->addAddress('[email protected]', 'Recipient Name');
$mail->Subject = 'Email with attachment';
$mail->Body = 'This is the email body';

// Add the attachment
$mail->addAttachment('path/to/attachment.txt', 'text/plain', 'attachment', 'attachment.txt');

// Set the SMTP server
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'username';
$mail->Password = 'password';

// Send the email
if (!$mail->send()) {
    echo 'Error: '. $mail->ErrorInfo;
} else {
    echo 'Email sent successfully';
}
?>

In this example, the PHPMailer instance is created and the email details are set using the setFrom(), addAddress(), Subject, and Body methods. The attachment is added using the addAttachment() method, and the SMTP server is set using the isSMTP(), Host, SMTPAuth, Username, and Password methods. Finally, the email is sent using the send() method, and an error message is displayed if the email is not sent successfully.
