打开一个目录，列出其中的文件，充值目录句柄，重新列出其中的文件，然后关闭：

$dir = "/images/";

// Open a directory, and read its contents

if

(is_dir($dir)){

if ($dh = opendir($dir)){

//

List files in images directory

while (($file = readdir($dh)) !== false){

echo "filename:" . $file . "
";

}

rewinddir();

// List once again files in images

directory

while (($file = readdir($dh)) !== false){

echo "filename:" . $file . "
";

}

closedir($dh);

}

}

?>

结果：

filename: cat.gif

filename: dog.gif

filename: horse.gif

filename: cat.gif

filename: dog.gif

filename: horse.gif
