PHP mail() Function

❮ PHP Mail Reference

Example

Send a simple email:

<?php
// the message
$msg = "First line of text\nSecond line of text";

// use wordwrap() if lines are longer than 70 characters
$msg = wordwrap($msg,70);

// send email
mail("someone@example.com","My subject",$msg);
?>

Definition and Usage

The mail() function allows you to send emails directly from a script.

Syntax

mail(to,subject,message,headers,parameters);

Parameter Values

Parameter Description
to Required. Specifies the receiver / receivers of the email
subject Required. Specifies the subject of the email. Note: This parameter cannot contain any newline characters
message Required. Defines the message to be sent. Each line should be separated with a LF (\n). Lines should not exceed 70 characters.

Windows note: If a full stop is found on the beginning of a line in the message, it might be removed. To solve this problem, replace the full stop with a double dot:
<?php
$txt = str_replace("\n.", "\n..", $txt);
?>

headers Optional. Specifies additional headers, like From, Cc, and Bcc. The additional headers should be separated with a CRLF (\r\n).

Note: When sending an email, it must contain a From header. This can be set with this parameter or in the php.ini file.

parameters Optional. Specifies an additional parameter to the sendmail program (the one defined in the sendmail_path configuration setting). (i.e. this can be used to set the envelope sender address when using sendmail with the -f sendmail option)


Technical Details
