Help with creating tags?

[code=php]//Tags
$tag_name = preg_replace(‘/^,/’,”,$tag);
$tag_name = preg_replace(‘/,$/’,”,$tag_name);
$tag_name = preg_replace(‘/s*/’,”,$tag_name);
$tag_name = $tag_name . ‘,’;
$num_tags = preg_replace(‘/[^,]+/’,”,$tag_name);
$num_tags = strlen($num_tags);
$tag = array();
while( $num_tags > 0 )
{
$tag[] = preg_replace(‘/,.*$/’,”,$tag_name);
$tag_name = preg_replace(‘/^[^,]+/’,”,$tag_name);
$tag_name = substr($tag_name,2,25);
$num_tags = $num_tags – 1;
}[/code]

I don’t know why, but the first letter of each tag always gets cut off. Help?
