PHP目录的遍历

//php目录的遍历
function showDetail($dirname){
$ds = opendir($dirname);
while($file = readdir($ds)){
$path = $dirname."/".$file;
if($file != "." && $file != ".."){  //这里是个坑
if(is_dir($path)){
showDetail($path);                 //递归调用，如果读出的是目录则继续读取
}else{
echo $path."";
}
}
}
}
$dirname="test";                 //测试一个目录
showDetail($dirname);
?>
