Send mail

bool **mail** string $to string $subject string $message  $additional_headers string $additional_params

Sends an email.

toReceiver, or receivers of the mail.

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

subjectSubject of the email to be sent.

Let op: > Subject must satisfy . RFC 2047

messageMessage to be sent.

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

Let op: > (Windows only) 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

additional_headers or to be inserted at the end of the email header. String``array

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.

   If an  is passed, its keys are the header names and its
   values are the respective header values.
  `array`

Opmerking: > When sending mail, the mail contain a header. This can be set with the parameter, or a default can be set in php.ini. mustFrom``additional_headers

    Failing to do this will result in an error
    message similar to .
    The  header sets also
     when sending directly via SMTP (Windows only).
   `Warning: mail(): "sendmail_from" not
    set in php.ini or custom "From:" header missing``From``Return-Path`

Opmerking: > If messages are not received, try using a LF (\n) only. Some Unix mail transfer agents (most notably ) replace LF by CRLF automatically (which leads to doubling CR if CRLF is used). This should be a last resort, as it does not comply with . qmailRFC 2822

additional_params The parameter can be used to pass additional flags as command line options to the program configured to be used when sending mail, as defined by the configuration setting. For example, this can be used to set the envelope sender address when using sendmail with the sendmail option. additional_params``sendmail_path``-f

   This parameter is escaped by  internally
   to prevent command execution.  prevents
   command execution, but allows to add additional parameters. For security reasons,
   it is recommended for the user to sanitize this parameter to avoid adding unwanted
   parameters to the shell command.
  `escapeshellcmd``escapeshellcmd`


   Since  is applied automatically, some characters
   that are allowed as email addresses by internet RFCs cannot be used. 
    can not allow such characters, so in programs where the use of
   such characters is required, alternative means of sending emails (such as using a framework
   or a library) is recommended. 
  `escapeshellcmd``mail`

The user that the webserver runs as should be added as a trusted user to the sendmail configuration to prevent a 'X-Warning' header from being added to the message when the envelope sender (-f) is set using this method. For sendmail users, this file is .

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.

Voorbeeld: Sending mail.

 Using  to send a simple email:
`mail`

<?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);
?>

Voorbeeld: 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);
?>

**Voorbeeld: Sending mail with extra headers as **

This example sends the same mail as the example immediately above, but passes the additional headers as array (available as of PHP 7.2.0).

<?php
$to      = 'nobody@example.com';
$subject = 'the subject';
$message = 'hello';
$headers = array(
    'From' => 'webmaster@example.com',
    'Reply-To' => 'webmaster@example.com',
    'X-Mailer' => 'PHP/' . phpversion()
);

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

Voorbeeld: Sending mail with an additional command line parameter.

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

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

Voorbeeld: Sending HTML email

 It is also possible to send HTML email with .
`mail`

<?php
// Multiple recipients
$to = 'johny@example.com, sally@example.com'; // note the comma

// 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>Johny</td><td>10th</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';
$headers[] = 'Content-type: text/html; charset=iso-8859-1';

// Additional headers
$headers[] = 'To: Mary <mary@example.com>, Kelly <kelly@example.com>';
$headers[] = 'From: Birthday Reminder <birthday@example.com>';
$headers[] = 'Cc: birthdayarchive@example.com';
$headers[] = 'Bcc: birthdaycheck@example.com';

// Mail it
mail($to, $subject, $message, implode("\r\n", $headers));
?>

Opmerking: > If intending to send HTML or otherwise Complex mails, it is recommended to use the PEAR package . PEAR::Mail_Mime

Opmerking: > The SMTP implementation (Windows only) of differs in many ways from the sendmail implementation. First, it doesn't use a local binary for composing messages but only operates on direct sockets which means a is needed listening on a network socket (which can either on the localhost or a remote machine). mail``MTA

Second, the custom headers like
,
,
 and
 are
 interpreted by the
 in the first place, but are parsed by PHP.

From:``Cc:``Bcc:``Date:notMTA

As such, the  parameter should not be an address
in the form of "Something <someone@example.com>". The
mail command may not parse this properly while talking with 
the MTA.

Opmerking: > It is worth noting that the function is not suitable for larger volumes of email in a loop. This function opens and closes an SMTP socket for each email, which is not very efficient. mail
