php遍历子文件

回复讨论(解决方案)

减少遍历的范围是唯一优化的方法
使用 glob 不递归或目录迭代器可使速度提高，但也有限

$p = './';$res = glob("$p/*");for($i=0; $i  
$path = '.';$ite = new RecursiveIteratorIterator( new RecursiveDirectoryIterator($path) );$deep = 0;foreach ($ite as $cur) {  $fn = $cur->getBasename();  if($fn == '.' || $fn == '..') continue;  $res[] = $fn;  if(($d=$ite->getDepth()) == $deep);  echo "$d $fn 
";}
