function only working on some servers

[sabret00the]

i've written this function (below), it takes

{TEXT1}
dfhdfkldfds;hdsfjsdfsdkfsdjkfhdsfsdjkfhdfjkdsfdsjk hd

{TEXT2}
fdkfdhfsldkfhdsfjlkhfdkjlfhdjkfldslkjfhsdhfldsfjhd sf


and converts the swirly brackets to lists, however it works perfectly on my localhost and on my test site, but on server for the production site, it refuses to work. any suggestions?

function get_thumbs_with_text($text, $picture_directory)
{
$titles = array();
foreach(explode("\n", $text) as $title)
{
if (!preg_match("/\{([^\}]+)\}(.+)/", $title, $regs))
{
continue;
}
$titles[$regs[1]] = $regs[2];
}

$thumbs_directory = $picture_directory . "/thumbs/";

foreach($titles AS $key => $value)
{
if ($handle = opendir($picture_directory))
{
while (false !== ($file = readdir($handle)))
{
if (!in_array($file, array(".", "..")) AND in_array(substr($file, -4), array('.jpg', 'jpeg', '.gif', '.png')))
{
$haystack = $file;
$needle = strtolower($key);
$pos = strpos($haystack, $needle);
if (!($pos === FALSE))
{
$img_dimentions = getimagesize($thumbs_directory . '/' . $file);
$picture_list .= '<li><a href="showpic.php?gallery=' . substr($picture_directory, 4) . '&amp;file=' . $file . '" target="_blank"><img src="' . $thumbs_directory . '/' . $file . '" width="' . $img_dimentions['0'] . '" height="' . $img_dimentions['1'] . '" alt="' . $file . '" class="thumbs" /></a>';
unset($img_dimentions);
}
}
}
closedir($handle);
}
$picture_list = (!$picture_list) ? "<li><img src=\"img/picturenotfound.gif\" /></li>" : $picture_list;
$list2[$key] = "<ul id=\"picturelist2\">" . $picture_list . "</ul>";
$picture_list = "";

$text = str_replace("{" . strtoupper($key) . "}", $list2[$key], $text);
}

$text = str_replace(
array(
"\r",
"<ul><br />",
"<li><br />",
"</li><br />",
"</ul><br />",
"</h3><br />",
"</h4><br />",
"method=\"post\"><br />",
"\"><br />",
"</div><br />"
),
array(
"<br />",
"<ul>",
"<li>",
"</li>",
"</ul>",
"</h3>",
"</h4>",
"method=\"post\">",
"\">",
"</div>"
),
$text);

return $text;
}


i originally thought about the php version, but since the production site is now on 5.0.5 and my localhost is 5.0.4, though i have a 4.3.3 that ran it fine, so it can't be that.

register_globals is set the same on all servers.

can you post the errormessage if it refuses to work?

php5 is more restrictive on some tihngs than php4 was

i actually got it to work, turns out that i was editing an old file and thus wasn't actually updating this one's regex which was causing the problems :o
