Description

int error_log ( string message [, int message_type [, string destination [, string extra_headers]]])

Sends an error message to the web server's error log, a TCP port or to a file. The first parameter, message, is the error message that should be logged. The second parameter, message_type says where the message should go:

Таблица 1. error_log() log types

0	`message` is sent to PHP's system logger, using the Operating System's system logging mechanism or a file, depending on what the error_log configuration directive is set to. This is the default option.
1	`message` is sent by email to the address in the `destination` parameter. This is the only message type where the fourth parameter, `extra_headers` is used. This message type uses the same internal function as mail() does.
2	`message` is sent through the PHP debugging connection. This option is only available if remote debugging has been enabled. In this case, the `destination` parameter specifies the host name or IP address and optionally, port number, of the socket receiving the debug information.
3	`message` is appended to the file `destination`.

Замечание: When explicitly specifying the message_type as 3, a newline is not automatically added to the end of the message string.

Внимание

Remote debugging via TCP/IP is a PHP 3 feature that is not available in PHP 4.
