PHP rewinddir() Function – Reset Directory Handle to the Beginning
The PHP rewinddir() function resets a directory handle opened by opendir() back to the start of the directory stream, returning the handle on success or FALSE on failure, and is illustrated with a complete example that reads, rewinds, and reads the directory contents again.
Function Definition
void rewinddir(resource $dir_handle)
Description
Resets the directory stream identified by $dir_handle to the beginning of the directory.
Parameters
dir_handle – The directory handle resource previously obtained via opendir() .
Return Value

Example
The following PHP code demonstrates opening a directory, listing its files, rewinding the handle with rewinddir() , listing the files again, and finally closing the directory.
<?php
$dir = "/images/";
if (is_dir($dir)) {
$dh = opendir($dir);
// List files in the images directory
while (($file = readdir($dh)) !== false) {
echo "filename:" . $file . "<br>";
}
// Reset the directory handle to the beginning
rewinddir();
// List files again after rewinding
while (($file = readdir($dh)) !== false) {
echo "filename:" . $file . "<br>";
}
closedir($dh);
}
