$o = scandir($dir);

print_r($o);
?>

Error 1:

Error 2:

Warning: scandir(/gallery/) [<a href='function.scandir'>function.scandir</a>]: failed to open dir: No such file or directory in C:\wamp\www\random1\index.php on line 3

Error 3:

Warning: scandir() [<a href='function.scandir'>function.scandir</a>]: (errno 2): No such file or directory in C:\wamp\www\random1\index.php on line 3

Answer 1

您正在搜索 /gallery/ 目录。第一个 / 表示它将从根开始搜索。删除它将使其相对。所以改变

$dir = "/gallery/";

至

$dir = "gallery";

Answer 2

你需要纠正你的路径。在路径中的任何内容之前使用斜杠将指定C:\wamp目录。哼哼 $dir = "/gallery";，会调查的C:\wamp。

假设您的目录结构是（在 www\your_project 目录中）

your_file_being_executed.php
gallery
    img.jpg

你可以使用$dir = "gallery"; And if 结构是

some_dir
   your_file_being_executed.php
gallery
   img.jpg

然后你可以使用$dir = "../gallery";

你也可以__Dir__和__FILE__语言常量。
