### 함수설명 ###

$_SERVER['PHP_SELF'] : 홈페이지 주소중 ***.com 등을 제외한 경로

/v4/about/greet.php  : 실제 열린 페이지
  예)  http://www.happyjung.com/v4/about/greet.php 인경우

각 메뉴를 아래와 같이 php코드처리하면 각 페이지가 열린후 왼쪽메뉴가 해당위치를 가르키고 있어서 직독성을 향상시킬수 있습니다.


### 일반적인 방식 ###
<table border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td><a href="/v4/about/greet.php" onMouseOut="MM_swapImgRestore()" onMouseOver="MM_swapImage('left01','','/v4/images/left_about_01_ov.gif',1)"><img src="/v4/images/left_about_01.gif" name="left01" width="180" height="24" border="0" id="left01"></a></td>
  </tr>
  <tr>
    <td><a href="/v4/about/history.php" onMouseOut="MM_swapImgRestore()" onMouseOver="MM_swapImage('left02','','/v4/images/left_about_02_ov.gif',1)"><img src="/v4/images/left_about_02.gif" name="left02" width="180" height="24" border="0" id="left02"></a></td>
  </tr>
</table>
