PHP Mail functions()

(PHP 4, PHP 5, PHP 7)

mail — Send mail

Description

bool mail ( string $to , string $subject , string $message [, string $additional_headers [, string $additional_parameters ]] )

Sends an email.

Parameters

to

Receiver, or receivers of the mail.

The formatting of this string must comply with » RFC 2822. Some examples are:

  • user@example.com
  • user@example.com, anotheruser@example.com
  • User <user@example.com>
  • User <user@example.com>, Another User <anotheruser@example.com>

subject

Subject of the email to be sent.

Caution

Subject must satisfy » RFC 2047.

message

Message to be sent.

Each line should be separated with a CRLF (\r\n). Lines should not be larger than 70 characters.

Caution

When PHP is talking to a SMTP server directly, if a full stop is found on the start of a line, it is removed. To counter-act this, replace these occurrences with a double dot.

<?php
$text = str_replace(“\n.”, “\n..”, $text);
?>

additional_headers (optional)

String to be inserted at the end of the email header.

This is typically used to add extra headers (From, Cc, and Bcc). Multiple extra headers should be separated with a CRLF (\r\n). If outside data are used to compose this header, the data should be sanitized so that no unwanted headers could be injected.

Return Values

Returns TRUE if the mail was successfully accepted for delivery, FALSE otherwise.

It is important to note that just because the mail was accepted for delivery, it does NOT mean the mail will actually reach the intended destination.

Changelog

Version Description
4.2.3 The additional_parameters parameter is disabled in safe_mode and the mail() function will expose a warning message and return FALSE when used.

Examples

Example #1 Sending mail.

Using mail() to send a simple email:

<?php
// The message
$message = “Line 1\r\nLine 2\r\nLine 3”;

// In case any of our lines are larger than 70 characters, we should use wordwrap()
$message = wordwrap($message, 70, “\r\n”);

// Send
mail(‘caffeinated@example.com’, ‘My Subject’, $message);
?>

Example #2 Sending mail with extra headers.

The addition of basic headers, telling the MUA the From and Reply-To addresses:

<?php
$to      = ‘nobody@example.com’;
$subject = ‘the subject’;
$message = ‘hello’;
$headers = ‘From: webmaster@example.com’ . “\r\n” .
‘Reply-To: webmaster@example.com’ . “\r\n” .
‘X-Mailer: PHP/’ . phpversion();

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

Example #3 Sending mail with an additional command line parameter.

The additional_parameters parameter can be used to pass an additional parameter to the program configured to use when sending mail using the sendmail_path.

<?php
mail(‘nobody@example.com’, ‘the subject’, ‘the message’, null,
‘-fwebmaster@example.com’);
?>

Example #4 Sending HTML email

It is also possible to send HTML email with mail().

<?php
// multiple recipients
$to  = ‘aidan@example.com’ . ‘, ‘; // note the comma
$to .= ‘wez@example.com’;

// subject
$subject = ‘Birthday Reminders for August’;

// message
$message = ‘
<html>
<head>
<title>Birthday Reminders for August</title>
</head>
<body>
<p>Here are the birthdays upcoming in August!</p>
<table>
<tr>
<th>Person</th><th>Day</th><th>Month</th><th>Year</th>
</tr>
<tr>
<td>Joe</td><td>3rd</td><td>August</td><td>1970</td>
</tr>
<tr>
<td>Sally</td><td>17th</td><td>August</td><td>1973</td>
</tr>
</table>
</body>
</html>
‘;

// To send HTML mail, the Content-type header must be set
$headers  = ‘MIME-Version: 1.0’ . “\r\n”;
$headers .= ‘Content-type: text/html; charset=iso-8859-1’ . “\r\n”;

// Additional headers
$headers .= ‘To: Mary <mary@example.com>, Kelly <kelly@example.com>’ . “\r\n”;
$headers .= ‘From: Birthday Reminder <birthday@example.com>’ . “\r\n”;
$headers .= ‘Cc: birthdayarchive@example.com’ . “\r\n”;
$headers .= ‘Bcc: birthdaycheck@example.com’ . “\r\n”;

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