LXVIII. Mail Functions


The mail() function allows you to send mail.


For the Mail functions to be available, PHP must have access to the sendmail binary on your system during compile time. If you use another mail program, such as qmail or postfix, be sure to use the appropriate sendmail wrappers that come with them. PHP will first look for sendmail in your PATH, and then in the following: /usr/bin:/usr/sbin:/usr/etc:/etc:/usr/ucblib:/usr/lib. It's highly recommended to have sendmail available from your PATH. Also, the user that compiled PHP must have permission to access the sendmail binary.


Для использования этих функций не требуется проведение установки, поскольку они являются частью ядра PHP.

Настройка во время выполнения

Поведение этих функций зависит от установок в php.ini.

Краткое разъяснение конфигурационных директив.

SMTP string

Used under Windows only: DNS name or IP address of the SMTP server PHP should use for mail sent with the mail() function.

smtp_port int

Used under Windows only: Number of the port to connect to the server specified with the SMTP setting when sending mail with mail(); defaults to 25. Only available since PHP 4.3.0.

sendmail_from string

Which "From:" mail address should be used in mail sent from PHP under Windows.

sendmail_path string

Where the sendmail program can be found, usually /usr/sbin/sendmail or /usr/lib/sendmail. configure does an honest attempt of locating this one for you and set a default, but if it fails, you can set it here.

Systems not using sendmail should set this directive to the sendmail wrapper/replacement their mail system offers, if any. For example, Qmail users can normally set it to /var/qmail/bin/sendmail or /var/qmail/bin/qmail-inject.

qmail-inject does not require any option to process mail correctly.

This directive works also under Windows. If set, smtp, smtp_port and sendmail_from are ignored and the specified command is executed.
