(PHP 4, PHP 5)

error_logSend an error message somewhere

Description

bool error_log ( string $message [, int $message_type = 0 [, string $destination [, string $extra_headers ]]] )

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

Parameters

message

The error message that should be logged.

message_type

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

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 No longer an option.
3 message is appended to the file destination. A newline is not automatically added to the end of the message string.
4 message is sent directly to the SAPI logging handler.

destination

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

extra_headers

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

Return Values

Returns TRUE on success or FALSE on failure.

Changelog

Version Description
5.2.7 The possible value of 4 was added to message_type.
