error_log returning file not found in PHP

Question

When I am trying to log the error from my Mysql class its saying file not found

even though the path is correct

here is the path

protected function sql_query($query){
        if (mysqli_query($this->conn,$query)){

                $last_id = mysqli_insert_id($this->conn);
                return $last_id;
            }
            else
                error_log(mysqli_error($this->conn) . "\n", 3, "../var/tmp/sql_error.log");
     }

So the folder looks like this

donations/api/dbHandeller.php

and the error log file is

donations/var/tmp/sql_error.log

ERROR

 error_log(../var/tmp/sql_error.log): failed to open stream: No such file or directory in <b>C:\xampp\htdocs\donations\api\dbHandeler.php

Thanks

You're trying to write to a relative path. What you want to do is write to an absolute path, using getcwd() .

error_log(mysqli_error($this->conn) . "\n", 3, getcwd() . "/var/tmp/sql_error.log");
