在codeigniter中，挂钩无法在服务器上运行

Question

I have created a hook for query log. Step 1 : $config['enable_hooks'] = TRUE; in config.php

Step 2 :

 $hook['post_controller'] = array(
    'class' => 'Db_log',
    'function' => 'logQueries', 
    'filename' => 'db_log.php', 
    'filepath' => 'hooks' 
);
// hooks.php

Step 3 : Hooks folder created the file called Db_log.php

Step 4 : Code in // Name of Class as mentioned in $hook['post_controller]

class Db_log {

    function __construct() {
        // Anything except exit()
    }

    // Name of function same as mentioned in Hooks Config
    function logQueries() {
        $CI = &get_instance();
        $filepath = APPPATH . 'logs/Query-log-' . date('Y-m-d') . '.php';
        $handle = fopen($filepath, "a+");
        $times = $CI->db->query_times;
        foreach ($CI->db->queries as $key => $query) {
            date_default_timezone_set("Asia/Bangkok");
            $sql = $query . " 
 Execution Time:" . $times[$key];
            fwrite($handle, $sql . "

");
        }
        $line .= "-----------------------------------------------
";
        fwrite($handle, $line . "
");
        fclose($handle);      // Close the file
    }
}

My Question is When ever controller is call then hook is running properly in local On server hook is not working, Set the permission 755,777,644 but still not working.

Answer 1

Please change array in hooks.php as bellow

$hook['post_controller'] = array(
    'class' => 'Db_log',
    'function' => 'logQueries', 
    'filename' => 'Db_log.php', 
    'filepath' => 'hooks' 
);
