// Access forbidden:
header('HTTP/1.1 403 Forbidden');

To get millisecond:

(float)microtime(true);

To get unique timestampe:

function uniqueTimeStamp()
    {
        $Asec = explode(" ", microtime());
        $Amicro = explode(".", $Asec[0]);
        return ($Asec[1] . substr($Amicro[1], 0, 4));
    }

preg_replace_callback in class

variable scope in PHP is painful. not like java or javascript, you can’t get preg_replace_callback works like this:

class test{
private $a = 'test';
public function foo($data){
   $a = $this->a;
   function nested($matches){
        return $matches[1].$a;
   }
   preg_replace_callback('/href=(.*?)/i','nested',$data);
}
}

what you have to do is like this:

class test{
private $a = 'test';
public function foo($data){
   $a = $this->a;
   $nested = function nested($matches){
        return $matches[1].$a;
   }
   preg_replace_callback('/href=(.*?)/i',array(get_class($this), 'bar'),$data);
}
private function bar($matches){
   return $matches[1].$this->a;
}
}
