php完美无沉余代码遍历文件夹
参数2
0 返回目录下文件
1 返回目录下文件+目录
2 返回目录下所有 文件+空文目录(为某些2类开发,头不合适了-_-b)
3 返回目录下所有 文件
4 返回目录下所有 文件+目录
5 返回目录下所有 目录
6 返回目录下目录

什么也不说直接上代码

function get_dir( $a, $s = 0, $d = array( '.', '..' ), $f = array() )
{
	foreach ( scandir( $a ) as $g )
	{
		if ( !in_array( $g, $d ) )
		{
			$g = $a . '/' . $g;
			if ( $s > 0 && is_dir( $g ) )
			{
				( $s == 1 || $s > 3 || ( $s == 2 && count( scandir( $g ) ) == 2 ) ) && $f[] = $g . '/';
				$s > 1 && $s < 6 && $f = get_dir( $g, $s, $d, $f );
			}
			else
			{
				( ( $s && $s < 5 ) || ( !$s && is_file( $g ) ) ) && $f[] = $g;
			};
		};
	};
	return $f;
}
