有时候再面试的时候会出这个题目，下面封装了个function 希望对网友用的上。

<?php /** 
* 遍历目录，结果存入数组。支持php4及以上。php5以后可用scandir()函数代替while循环。 
* @param string $dir 
* @return array 
*/ function my_scandir($dir) 
{ 
    $files = array(); 
    if ( $handle = opendir($dir) ) { 
        while ( ($file = readdir($handle)) !== false )  
        { 
            if ( $file != ".." && $file != "." )  
            { 
                if ( is_dir($dir . "/" . $file) )  
                { 
                    $files[$file] = my_scandir($dir . "/" . $file); 
                } 
                else
                { 
                    $files[] = $file; 
                } 
            } 
        } 
        closedir($handle); 
        return $files; 
    } 
}



demo2：

 
 function my_scandir1($dir) 
{ 
    $files = array(); 
    $dir_list = scandir($dir); 
    foreach($dir_list as $file) 
    { 
        if ( $file != ".." && $file != "." )  
        { 
            if ( is_dir($dir . "/" . $file) )  
            { 
                $files[$file] = my_scandir1($dir . "/" . $file); 
            } 
            else
            { 
                $files[] = $file; 
            } 
        } 
    } 
     
    return $files; 
} 
 $result = my_scandir('./'); $result = my_scandir1('./'); 
?>



<?php

set_time_limit(0);

function tree($directory)

{

$mydir=dir($directory);

echo "<ul> ";

while($file=$mydir->read()){

if((is_dir("$directory/$file")) AND ($file!=".") AND ($file!=".."))

{

        echo "<li><font color='#ff00cc'><b>$file</b></font></li> ";

tree("$directory/$file");

}

else

        {

echo "<li>$file</li> ";

        }

}

echo "</ul>

";

$mydir->close();

}

//start the program

echo "<h2>目录为粉红色</h2>

";

tree(".");

?>
