使用PHP遍历文件夹与子目录的函数代码

function get_dir_scandir(){
$tree = array();
foreach(scandir('./') as $single){
echo $single."<br/>\r\n";
}
}
get_dir_scandir();

function get_dir_glob(){
$tree = array();
foreach(glob('./*') as $single){
echo $single."<br/>\r\n";
}
}
get_dir_glob();

//Update at 2010.07.25 - 以下代码作废
$path = '..';
function get_filetree_scandir($path){
$tree = array();
foreach(scandir($path) as $single){
if(is_dir('../'.$single)){
$tree = array_merge($tree,get_filetree($single));
}
else{
$tree[] = '../'.$single;
}
}
return $tree;
}
print_r(get_filetree_scandir($path));

//Update at 2010.07.25 - 以下为新代码
$path = './';
function get_filetree_scandir($path){
$result = array();
$temp = array();
if (!is_dir($path)||!is_readable($path)) return null; //检测目录有效性
$allfiles = scandir($path); //获取目录下所有文件与文件夹
foreach ($allfiles as $filename) { //遍历一遍目录下的文件与文件夹
if (in_array($filename,array('.','..'))) continue; //无视 . 与 ..
$fullname = $path.'/'.$filename; //得到完整文件路径
if (is_dir($fullname)) { //是目录的话继续递归
$result[$filename] = get_filetree_scandir($fullname); //递归开始
}
else {
$temp[] = $filename; //如果是文件，就存入数组
}
}
foreach ($temp as $tmp) { //把临时数组的内容存入保存结果的数组
$result[] = $tmp; //这样可以让文件夹排前面，文件在后面
}
return $result;
}
print_r(get_filetree_scandir($path));

$path = '..';
function get_filetree($path){
$tree = array();
foreach(glob($path.'/*') as $single){
if(is_dir($single)){
$tree = array_merge($tree,get_filetree($single));
}
else{
