Introduction
Sending emails in PHP is necessary for web developers who are working on applications that need to send emails. Email is mainly used for communication between applications and users. PHP mail function is an inbuilt PHP function that allows developers to send emails from PHP scripts quickly. In this article, we will discuss PHP mail function and how to use it.
What is PHP mail function?
PHP mail function is used for sending emails from PHP to users. It is an inbuilt function in PHP that allows developers to send email messages to users. It is an easy-to-use function that accepts several parameters such as email recipient, subject, and message content.
The PHP mail function works by sending an email message to a mail server. The mail server then forwards the message to the recipient’s email server. The recipient’s email server will then deliver the message to the recipient’s mailbox.
How to use PHP mail function
To use the PHP mail function, you need to pass the recipient’s email address, subject, and message content as parameters. The syntax for the PHP mail function is as follows:
mail($to, $subject, $message, $headers);- $to: Recipient’s email address
- $subject: Email subject
- $message: Email message content
- $headers: Optional headers for the email message
Here is an example of how to use the PHP mail function:
$to = "example@email.com";
$subject = "Test email";
$message = "This is a test email sent from PHP";
$headers = "From: webmaster@domain.com";
mail($to, $subject, $message, $headers);Sending HTML emails using PHP mail function
Sending HTML emails is a common practice in web development. HTML emails provide more flexibility in terms of formatting and styling compared to plain text emails. To send an HTML email using PHP mail function, you need to set the content-type header to “text/html”. Here’s an example:
$to = "example@email.com";
$subject = "HTML email";
$message = "
<html>
<head>
<title>HTML Email</title>
</head>
<body>
<h1>This is an HTML email sent from PHP</h1>
</body>
</html>
";
$headers = "From: webmaster@domain.com\r\n";
$headers .= "Content-Type: text/html\r\n";
mail($to, $subject, $message, $headers);Adding attachments to email using PHP mail function
Sometimes, you may need to attach files to an email message. PHP mail function allows you to attach files to an email using MIME type. Here is an example of how to attach a file to an email using PHP mail function:
$to = "example@email.com";
$subject = "Attachment email";
$message = "This is an email with an attachment";
$headers = "From: webmaster@domain.com";
$file_name = "attachment.pdf";
$file_path = "/path/to/attachment.pdf";
$file_type = "application/pdf";
$file_size = filesize($file_path);
$attachment = chunk_split(base64_encode(file_get_contents($file_path)));
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: multipart/mixed; boundary=\"boundary1\"\r\n";
$headers .= "Content-Disposition: attachment; filename=\"$file_name\"\r\n";
$headers .= "Content-Transfer-Encoding: base64\r\n\r\n";
$body = "--boundary1\r\n";
$body .= "Content-Type: text/plain; charset=\"iso-8859-1\"\r\n";
$body .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
$body .= "$message\r\n\r\n";
