Random Signature

Random Signature Generator:

For this tutorial I will simply show you a few ways to do each part and put one way together for you. It will be a simple random signature generator. First of all you will need some signatures I will be using these listed below. Something to note remember is that the default forum sig: 400x100

• http://i44.tinypic.com/9fqwb9.gif
• http://i44.tinypic.com/ip4f8m.gif
• http://i41.tinypic.com/2d5t1t.gif

Now to start off we need to be able to find them when we need them we can either put them into an array or put them into a local directory and scan for them.

<?PHP
//array of images
$sig[] = "http://i44.tinypic.com/9fqwb9.gif";
$sig[] = "http://i44.tinypic.com/ip4f8m.gif";
$sig[] = "http://i41.tinypic.com/2d5t1t.gif";

$files = scandir("/homepages/blainesch/htdocs/signatures/");
$ext = "gif"; //extension you want - change to anything!
$start = strlen($ext) - (strlen($ext)*2); //gets the negative number
$end = strlen($ext);
foreach($files as $file) {
    if(substr($file, $start, $end) == $ext) {
        $sig[] = "http://yoursite.com/signatures/".$file;
    }
} 

Now we should all have an array of $sigs! Now to display or not to display - that is the question!

We can either go about this by forwarding the user to the address which is probably the cheaper way of doing it but will work in most forum signatures I would assume. It worked when I tried it on codecall. Or we can actually generate the page.

header('Location: '.$sig[mt_rand(0, count($sig)-1)]); 

header('Content-type: image/gif');
$im = imagecreatefromgif($sig[mt_rand(0,count($sig)-1)]);
imagegif($im); 

So to sum it all up...

<?PHP
//array of images
$folder = "/homepages/blainesch/htdocs/siggys/";
$files = scandir($folder);
$ext = "gif";
$start = strlen($ext) - (strlen($ext)*2);
$end = strlen($ext);
foreach($files as $file) {
    if(substr($file, $start, $end) == $ext) {
        $sig[] = $folder.$file;
    }
}
header('Content-type: image/gif');
$im = imagecreatefromgif($sig[mt_rand(0,count($sig)-1)]);
imagegif($im);
?>
