PHP error_log() Function

Hello folks! welcome back to a new section of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP error_log() Function.

The built-in PHP error_log() function sends an error message to the web server's error log, a TCP port or to a file.


Following below is the syntax to use this function -

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

Parameter Details

Sr.NoParameter & Description


The error message that should be logged.



It says where the error should go. The possible message types are as follows −

  • 0 − Default. The error is sent to the servers logging system or a file, depending on how the error_log configuration is set in the php.ini file

  • 1 − The error is sent by email to the address in the destination parameter. This message type is the only one that uses the headers parameter

  • 2 − The error is sent through the PHP debugging connection. This option is only available in PHP 3

  • 3 − The error is added to the file destination string



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



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.
