PHP 掃描文件名,遍歷二維數組

掃描目錄下的文件名

<?php
//自定義函數
 function myreaddir($dir) {
        $handle=opendir($dir);
        $i=0;
        while(!!$file = readdir($handle)) {
            if (($file!=".")and($file!="..")) {
                $list[$i]=$file;
                $i=$i+1;
            }
        }
        closedir($handle);
        return $list;
    }
 echo '<hr />';
		  
$facearray = myreaddir(dirname(__FILE__)."/tools");
//  myreaddir(dirname(__FILE__)  獲取當前文件目錄

foreach ($facearray as $num){
	echo $num.'<br />';
}
		  
?>

$tools  = array(
     "one" => array(1,2,3,4),
     "two" => array(5,6,7,8),
     "three" => array('a','b','c','d')
