PHP displays the file where the current file is located and all files in the folder expanded in a tree shape

复制代码代码如下:

<div id="jQ-menu">

<?php

$path = "./";

function createDir($path = '.')

{

if ($handle = opendir($path))

{

echo "<ul>";

while (false !== ($file = readdir($handle)))

{

if (is_dir($path.$file) && $file != '.' && $file !='..')

printSubDir($file, $path, $queue);

else if ($file != '.' && $file !='..')

$queue[] = $file;

}

printQueue($queue, $path);

echo "</ul>";

}

}

function printQueue($queue, $path)

{

foreach ($queue as $file)

{

printFile($file, $path);

}

}

function printFile($file, $path)

{

echo "<li><a href=/"".$path.$file."/">$file</a></li>";

}

function printSubDir($dir, $path)

{

echo "<li><span class=/"toggle/">$dir</span>";

createDir($path.$dir."/");

echo "</li>";

}

createDir($path);

?>

</div>
