Quick Reference
The PHP rewinddir() function resets the directory handle created by opendir().
<?php
$dir = '/images/';
// open a directory and read its contents
if (is_dir($dir)) {
if ($dh = opendir($dir)){
while (($file = readdir($dh)) !== false) {
echo 'filename:' . $file . '<br>';
}
rewinddir();
// list the files in images directory again
while (($file = readdir($dh)) !== false) {
echo 'filename:' . $file . '<br>';
}
closedir($dh);
}
}
?>
Output
filename: image1.jpg
filename: image2.jpg
filename: logo.png
filename: image1.jpg
filename: image2.jpg
filename: logo.png
Syntax

PHP Notes:
- When using PHP, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
