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: image2.jpg
filename: logo.png
filename: image1.jpg

filename: logo.png

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
