Hi Reader's,
Welcome to FindNerd, today we are going to discuss how to use error_log() function in php ?

The error_log() function is used for sending an error message to a log, to a file, or to a mail account.
The error_log() function always returns TRUE on success or FALSE on failure.

syntax of error_log() function

error_log(message,type,destination,headers);

"message" is a required parameter
"type" is a optional parameter
"destination " is a optional parameter
"headers "is a optional parameter

you can see bellow example:

<?php

// Send a error message to the server log if error connecting to the database
if (!mysqli_connect("localhost","usrname","password","database")) {
  //here call error_log()
    error_log("Failed! unable to connect to database!", 0);
}

?>
