<?php
if($_SERVER['REQUEST_METHOD'] == 'POST'){
if(isset($_POST['nums']) && isset($_POST['special']))
$string = 'abcdefghjkmnpqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ123456789!#$@%&()_+';
else if (isset($_POST['nums'])) $string = 'abcdefghjkmnpqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ123456789';
else if (isset($_POST['special'])) $string = 'abcdefghjkmnpqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ!#$@%&()_+';
else $string = 'abcdefghjkmnpqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ';

The PHP coding in box below redirects to a URL:
15
<?php header("Location: current.php"); ?>

$images = glob($dir_name."*.*");
foreach($images as $image) {
echo "<img src="" /><br />";
}
?>

<h4 class="glow"><a href="<?php echo "$url.php"; ?>" title="<?php echo "$url"; ?>"><?php echo "$url"; ?></a></h4>
</div>
<?php
// get current directory path
$dirpath = "snips/*$url.txt";
// copy filenames to array
$files = array();
$files = glob($dirpath);
foreach($files as $item){
$all_lines = file($item);
$file1 = "$item";
$lines = file($file1);
foreach($lines as $line_num => $line){
$link = str_replace(" ", "-", $line);
echo "<a href=$url.php#$link>$line</a><br />";

usort($files, function($x, $y) {
return filemtime($x) < filemtime($y);

$all_lines = file($item);
echo "<h5>";
echo "<span>ok $all_lines[0]</span>";
echo "</h5>";
