Описание

Sends an error message to the web server's error log, a TCP port or to a file.

Список параметров

message

The error message that should be logged.

message_type

Says where the error should go. The possible message types are as follows:

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.
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. This option is only available in PHP 3.
3- message is appended to the file destination. A newline is not automatically added to the end of the message string.

destination

The destination. Its meaning depends on the message parameter as described above.

extra_headers

The extra headers. It's used when the message parameter is set to 1. This message type uses the same internal function as mail() does.
