Question

I am trying to make a script which changes the favicon at every refresh.

<?php
 $dir = "img/icons/";
 $files = array();
 if ($handle = opendir($dir)) {
   while (false !== ($file = readdir($handle))) {
    $files[] = $file;
   }
 }
 $icon = $files[rand(2,count($files)-1)];
 echo "<LINK REL=\"shortcut icon\" HREF=\'img/icons/'.$icon."\">";
?>

This script gets every favicon from the /img/icons folder, and randomly selects one. The problem is that when I paste it in my HTML file, weird characters appear at the top of the page “; ?>.Can anyone fix my script ?

<?php
 $dir = "img/icons/";
 $files = array();
 if ($handle = opendir($dir)) {
   while (false !== ($file = readdir($handle))) {
    $files[] = $file;
   }
 }
 $icon = $files[rand(2,count($files)-1)];
 echo '<LINK REL="shortcut icon" HREF="img/icons/'.$icon.'">';
?>

Here you can have a look at using PHP in HTML. Also your server should be properly configured for this. I always recommend .php to deal with PHP scripts.

Hope this helps.
