index.php

Code:

error_reporting(E_ALL | E_STRICT);
  ini_set('display_errors','On');
  
  date_default_timezone_set('Asia/Krasnoyarsk'); // Bangkok time
  define('LOCALHOST', 'localhost' === $_SERVER['SERVER_NAME']);
  define('BR', '<br />');

  //==========================================================================  
  function fred($msg=array('one', 'two', 'three'), $msg_name='$msg_name not passed') {
  echo "<pre style='text-align:left;background:#ffc none;color:#000;text-align:left'>";

        echo '<b>' .$msg_name .'</b> ==> <span>';
                print_r($msg);
                echo BR;
        echo "</span></pre>";

  }//endfunc

Code usage: // can be in controllers, views, models, libraries, etc

Code:

if (LOCALHOST)
  {
    echo BR .'None of this is shown online';

    $atest = array('one', 'two', 'three');
    fred($atest, '$atest');
  }
