mb_send_mail — Send encoded mail
$to
,$subject
,$message
,$additional_headers
= [],$additional_params
= null
Sends email. Headers and messages are converted and encoded according to the mb_language() setting. It's a wrapper function for mail(), so see also mail() for details.
to
The mail addresses being sent to. Multiple
recipients may be specified by putting a comma between each
address in to
.
This parameter is not automatically encoded.
subject
The subject of the mail.
message
The message of the mail.
additional_headers
(optional)String or array 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). Validate parameter not to be injected unwanted headers by attackers.
If an array is passed, its keys are the header names and its values are the respective header values.
Note:
When sending mail, the mail must contain a
From
header. This can be set with theadditional_headers
parameter, or a default can be set in php.ini.Failing to do this will result in an error message similar to
Warning: mail(): "sendmail_from" not set in php.ini or custom "From:" header missing
. TheFrom
header sets alsoReturn-Path
under Windows.
Note:
If messages are not received, try using a LF (\n) only. Some Unix mail transfer agents (most notably » qmail) 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 » RFC 2822.
additional_params
additional_params
is a MTA command line
parameter. It is useful when setting the correct Return-Path
header when using sendmail.
This parameter is escaped by escapeshellcmd() internally to prevent command execution. escapeshellcmd() prevents command execution, but allows to add additional parameters. For security reason, this parameter should be validated.
Since escapeshellcmd() is applied automatically, some characters that are allowed as email addresses by internet RFCs cannot be used. Programs that are required to use these characters mail() cannot be used.
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 /etc/mail/trusted-users.
Returns true
on success or false
on failure.
