How sort my images on this php script

[johngary]

I'm bit new to php and I got this code on my site but however Id like this to change the images to show up in the right order of sequence. My images are number from 1.jpg, 2.jpg and so on but on my site it appears to be in random...

Anyone please can fixed this...

 

<?php

$p = $_GET['p'];

if ($handle = opendir("images/rootfolder/")) {

$i = 1;

while (false !== ($file = readdir($handle))) {

if ($file != "." && $file != "..") {

$img[$i] = $file;

if ($p == $img[$i]) {

$ci = $i;

}

$i++;

}

}

closedir($handle);

$ti = $i - 1;

$pi = $ci - 1;

if ($p == "") {

$ni = $ci + 2;

} else {

$ni = $ci + 1;

}

$prevNext = "";

if ($pi > 0) {

$piFile = $img[$pi];

$prevNext .= "<a href=\"" . $_SERVER['PHP_SELF'] . "?p=" . $piFile . "\" title=\"show previous image\">Previous</a>";

} else {

$prevNext .= "Previous";

}

$prevNext .= " | ";

if ($ni <= $ti) {

$niFile = $img[$ni];

$prevNext .= "<a href=\"" . $_SERVER['PHP_SELF'] . "?p=" . $niFile . "\" title=\"show next image\">Next</a>";

} else {

$prevNext .= "Next";

}

if ($p == "") {

$p = $img[1];

}

}

?>

Please post code in code tags, it makes it easier to read. You have an array of images called $img, but I don't see you using sort() anywhere.
