这几天都出奇的忙，没有时间上博客写东西！
稍微有点空闲，却用于睡觉、喝水和上厕所。
不过，晚上还是忙里偷闲的看了几行代码，是关于F2BLOG的。不敢对这个博客程序妄加评价，做出来的东西都一定付出了辛勤劳动的，这个我是深知的。它给我的最深刻的印象是作者对于数组巧妙淋漓的运用，真的很佩服，有很多地方让人眼前一亮的感觉：“啊！原来数组还可以这样用啊！”，几乎有些出神入化，多处使用的三维数组是我在很多程序中都没有看到过的。
数组的应用让这个程序变的异常灵活，容错性好，易扩展，易维护~因此，几乎是在看代码的同一时刻做的决定，以后一定要多用数组，把这个强大的功能发挥一下。不错！数组也让OO思想在我脑子里有了新的认识。来看一段个人认为比较精彩的代码(后台菜单的灵活加载)：

<ul id="adminmenu">
<?php  
$menuTitle=array($strGentralMang,$strCategoryTag,$strLogManagement,$strLinkManagement,$strUserMang,$strSkinManagement,$strAdvancedManagement,$strDataManagement);

if ($DMC->fetchArray($DMC->query("select * from ".$DBPrefix."links where isApp='0'"))){
  $menulink=array("control.php","categories.php","logs.php","linkapp.php","users.php","skins.php","filters.php","cache.php");
}else{
  $menulink=array("control.php","categories.php","logs.php","links.php","users.php","skins.php","filters.php","cache.php");
}
$submenuTitle[0]=array($strControlPanel,$strSettingBlogs,$strSettingSideBar,$strSettingContent,$strSettingSideCalendarSet,$strOtherSetting,$strServerInfo,$strCheckUpdate,$strForumData,$strAboutF2Blog);
$submenuLink[0]=array("control.php","setting.php?set=1","setting.php?set=2","setting.php?set=3","setting.php?set=4","setting.php?set=5","sysinfo.php","checkupdate.php","myforum.php","about.php");
$submenuTitle[1]=array($strCategory,$strTag);
$submenuLink[1]=array("categories.php","tags.php");
$submenuTitle[2]=array($strLogBrowse,$strLogNew,$strCommentBrowse,$strTrackbackBrowse,$strGuestBookBrowse);
$submenuLink[2]=array("logs.php","logs.php?action=add","comments.php","trackback.php","guestbooks.php");
$submenuTitle[3]=array($strLinkManagement,$strLinksAdd,$strlinkgroupTitle,$strLinksApp);
$submenuLink[3]=array("links.php","links.php?action=add","linkgroup.php","linkapp.php");
$submenuTitle[4]=array($strUserMang,$strUserAdd,$strLogsEditAuthor);
$submenuLink[4]=array("users.php","users.php?action=add","editauthor.php");
$submenuTitle[5]=array($strSkinSetting,$strModuleSetting,$strPluginSetting);
$submenuLink[5]=array("skins.php","modules.php","plugins.php");
$submenuTitle[6]=array($strFilter,$strKeyword,$strEditorPlugins,$strStatistics);
$submenuLink[6]=array("filters.php","keywords.php","editor_plugins.php","statistics.php");
$submenuTitle[7]=array($strCache,$strAttachment,$strBackup,$strRestore,$strOptimize,$strRssExport,$strRssImport);
$submenuLink[7]=array("cache.php","attachments.php","db_backup.php","db_restore.php","db_tools.php","rss_export.php","rss_import.php");

//角色权限
$mainRoleAdmin=array("1","1","1","1","1","1","1","1");
$mainRoleEditor=array("1","1","1","1","0","0","1","0");
$mainRoleAuthor=array("1","0","1","0","0","0","0","0");
$subRoleAdmin=array("1,1,1,1,1,1,1,1,1,1","1,1","1,1,1,1,1","1,1,1,1","1,1,1","1,1,1","1,1,1,1","1,1,1,1,1,1,1");
$subRoleEditor=array("1,0,0,0,0,0,0,1,1,1","1,1","1,1,1,1,1","1,1,1,1","0,0,0","0,0,0","1,1,1,0","0,0,0,0,0,0,0");
$subRoleAuthor=array("1,0,0,0,0,0,0,1,1,1","0,0","1,1,0,0,0","0,0,0,0","0,0,0","0,0,0","0,0,0,0","0,0,0,0,0,0,0");

if ($_SESSION['rights']=="admin") {
  $curMainRole=$mainRoleAdmin;
  $curSubRole=$subRoleAdmin;
} else if ($_SESSION['rights']=="editor") {
  $curMainRole=$mainRoleEditor;
  $curSubRole=$subRoleEditor;
} else if ($_SESSION['rights']=="author") {
  $curMainRole=$mainRoleAuthor;
  $curSubRole=$subRoleAuthor;
}

foreach ($menuTitle as $index => $item) {
  if ($_SESSION['rights']=="admin" or $curMainRole[$index]=="1") {
    $class=($parentM==$index)?' class="current"':'';
    echo "\n\t<li><a href='{$menulink[$index]}'$class>{$item}</a></li>";
  }
}
?>
</ul>

<ul id="submenu">
<?php
$curSubRoleT=explode(",",$curSubRole[$parentM]);
foreach ($submenuTitle[$parentM] as $index => $item){
  if ($mtitle==$item) { $parentS=$curSubRoleT[$index]; }
  if (isset($curSubRoleT[$index]) && $curSubRoleT[$index]=="1") {
    $class=($mtitle==$item)?' class="current"':'';
    echo "\n\t<li><a href='{$submenuLink[$parentM][$index]}'$class>{$item}</a></li>";
  }
}
?>
</ul>

这是admin/admin_menu.php中挖出来的一段代码，个人觉得是相当的精彩，几乎是所见即所得的效果，后台的菜单布局一目了然，想修改哪个菜单变的非常简单，对全局的影响非常小。好代码，好代码，好代码……回味无穷~
