Example 1

Simplest and smallest example explaining the usage of this function is shown below.

<?php
	mail("me@example.com","My subject","Hello myself, how are you.");
?>

Example 2

An advanced usage of this mail function is shown below which can be modified by you for your own use. In this example we will send an HTML email to the recipient.

<?php
$to = "firstPERSON@example.com, SECONDperson@example.com";
$subject = "MY HTML EMAIL";

$email = "
<html>
<head>
<title>MY HTML EMAIL</title>
</head>
<body>
<div id="header" style="margin:10px;background-color:red;padding:10px;">
	<h1> MY Website Name</h1>
</div>
<div id=body" style="margin:10px;background-color:pink;padding:10px;">
	<p> What's up man????? </p>
</div>
</body>
</html>
";

// Always set content-type when sending HTML email
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n";

// More headers
$headers .= 'From: <myself@example.com>' . "\r\n";
$headers .= 'Cc: my2ndEmailID@example.com' . "\r\n";

mail($to,$subject,$message,$headers);
?> 

In the above code, Cc indicates Carbon Copy means a copy of same email will be sent to email ids beside on Cc.

  • Cc: Carbon copy - Every recipient can see email id's of other recipients of that email.
  • Bcc: Blind Carbon Copy - Nobody can see email id of other recipients of that email.
