<?php$dirURL = '.';  //base direction, related url

        echo "<a href=\"$file\">".$file."</a>";
        echo "<br>";
}
function PrintErr($file) {
        echo "<font color=red>error :</font> {$file}! Maybe the program is something wrong!<br>";

Answer 1

难看了点……./1.php
./py
    ./py/getpy.php
    ./py/py.dat
./2.php
./tv.html
./style.css
./tv.js
./3.php
./a.php
./upfiles
    ./upfiles/Note.txt

Answer 2

function PrintFileName($file, $nIndent) {
        echo "|-";
        for( $i=0; $i<$nIndent; $i++ )        echo "--";
        echo "<a href=\"$file\">".str_replace("./","",$file)."</a>";
        echo "<br>";
}这样可以变得好看点.

我把$dirURL = ". " 改成了 $dirURL = "C:"结果程序只能显示几秒钟，然后就显示找不到服务器，是咋会事啊？
