PHP - Mail
The mail() function allows you to send emails directly from a script.
Installation
There is no installation needed to use these functions. These functions are part of the PHP core.
Runtime Configuration
The behavior of these functions is affected by settings in php.ini.
Mail Configuration Options
| Name | Default | Description | Changeable |
|---|---|---|---|
| mail.add_x_header | "0" | Add X-PHP-Originating-Script that will include UID of the script followed by the filename. | PHP_INI_PERDIR |
| mail.log | NULL | The path to a log file that will log all mail() calls. Log entries include the full path of the script, line number, To address and headers. | PHP_INI_SYSTEM | PHP_INI_PERDIR |
| mail.force_extra_parameters | NULL | Force the addition of the specified parameters to be passed as extra parameters to the sendmail binary. These parameters will always replace the value of the 5th parameter to mail(), even in safe mode. | PHP_INI_SYSTEM | PHP_INI_PERDIR |
| SMTP | "localhost" | Windows only: host name or IP address of the SMTP server PHP should use for mail sent with the mail() function. | PHP_INI_ALL |
| smtp_port | "25" | Windows only: Number of the port to connect to the server specified with the SMTP setting when sending mail with mail(); defaults to 25. | PHP_INI_ALL |
| sendmail_from | NULL | Which "From:" mail address should be used in mail sent directly via SMTP (Windows only). This directive also sets the "Return-Path:" header. | PHP_INI_ALL |
| sendmail_path | "/usr/sbin/sendmail -t -i" | Where the sendmail program can be found, usually /usr/sbin/sendmail or /usr/lib/sendmail. 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. | PHP_INI_SYSTEM |
