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：

<?PHP
$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:" . $file . "<br>";
 }
 rewinddir();
 // List once again files in images directory
 while (($file = readdir($dh)) !== false){
 echo "filename:" . $file . "<br>";
 }
 closedir($dh);
 }
}
?>

结果：

filename: cat.gif
 filename: dog.gif
 filename: horse.gif
filename: cat.gif
 filename: dog.gif
 filename: horse.gif
