AJAX request runs a RAW parameterized Postgres SQL Query after receiving request

Suppose we have a situation like that

Here's my situation

in my php view file, I make AJAX request to the server

The AJAX request is received and runs a RAW parameterized Postgres SQL query (e.g.

DB::select('select * from my_table where id=?', array(1))

Then to solve this problem we will use such logging sql query.

if (Config::get('database.log', false))
{           
    Event::listen('illuminate.query', function($query, $bindings, $time, $name)
    {
        $data = compact('bindings', 'time', 'name');

        // Format binding data for sql insertion
        foreach ($bindings as $i => $binding)
        {   
            if ($binding instanceof \DateTime)
            {   
                $bindings[$i] = $binding->format('\'Y-m-d H:i:s\'');
            }
            else if (is_string($binding))
            {   
                $bindings[$i] = "'$binding'";
            }   
        }       

        // Insert bindings into query
        $query = str_replace(array('%', '?'), array('%%', '%s'), $query);
        $query = vsprintf($query, $bindings); 

        Log::info($query, $data);
    });
}

By this way we can deal with sql logging query.
