It is crucial to note that rewinddir() does not simply start over at the beginning of the SAME directory list. Instead, this function first re-reads the directory - thus any file that were deleted (or inserted) since the original opendir() will be reflected after "rewinding".In that respect, rewinddir() is equivalent to a closedir(), opendir() sequence, but without obtaining a new handle./* Source Code */<?php$dir = "/images/";// Open a directory, and read its contentsif (is_dir($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); }}?>/* Result */filename: cat.giffilename: dog.giffilename: horse.giffilename: cat.giffilename: dog.giffilename: horse.gif
