ERROR_LOG
Send an error message to the defined error handling routines
SYNTAX
error_log ( string $message [, int $message_type = 0 [, string $destination [, string $extra_headers ]]] ) : bool
PARAMETERS
message
The error message that should be logged.
message_type
Says where the error should go. The possible message types are as follows:
| 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
Returns TRUE on success or FALSE on failure.
