1. Send Plain Text Email
The easiest way to send an email with PHP is to send a plain text email. The below example defines how to send a simple text email from PHP application. First we declare the variables in order recipient's email address, subject of email and message to be send and headers, then we pass these variables to the mail() function to send the email.
<?php
$recipient = 'test@test.com';
$subject = 'Testing email';
$message = "Hello User!\n\nThis email is for testing.";
$headers = "From: admin@test.com\r\nReply-To: info@test.com";
$mail = @mail( $recipient, $subject, $message, $headers );
//Check if the mail is sent successfully or not
if($mail){
echo "Email send successfully.";
}else{
echo "Email can not send.";
}
?>
2. Send HTML Email using PHP
Usually when we send a simple email using PHP then all the content will be treated as simple text. We can also send an HTML formatted email using PHP mail() function which improves the output.
<?php
$recipient = 'youraddress@example.com';
$subject = 'Test for HTML email';
//Content-type always be set
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
$headers = "From: admin@test.com\r\nReply-To: info@test.com";
$message = '<html><body>';
$message .= '<h2>Hello World!</h2>';
$message .= '<p style="color:#f00;font-size:12px;">This is HTML email for testing.</p>';
$message .= '</body></html>';
if(mail($recipient, $subject, $message, $headers)){
echo "Email send successfully.";
} else{
echo "Email can not send.";
}
?>
