递归显示当前目录树，可自定义结点标记
//静态层级数static $i = 0;//递归目录function showfile($dir){global $i;$d = dir($dir);//echo "Handle: " . $d->handle . "\n";//echo "Path: " . $d->path . "\n";$i++;$space = printSpace($i);while ( false !== ($entry = $d->read ()) ) {//echo $entry . "<br />";//echo "<font color=red>".$dir."/".$entry."</font><br/>";if($entry!='.' && $entry!='..' && is_dir($dir."/".$entry)){echo "<font color=red>".$space.$entry."</font><br/>";showfile($dir."/".$entry);}else{if(is_file($dir."/".$entry)){echo $space.$entry."<br/>";}}}$d->close ();$i--;}//自定义输出层级标记,默认-function printSpace($num,$concatStr='-'){for($i=0;$i<$num;$i++){$str.=$concatStr;}return $str;}//示例: 当前目录showfile(dirname(__file__));?
输出如下格式(红色为目录)：
