Getting a syntax error

[SirTalksalot]

Hi all,

I'm getting an odd syntax error, can someone tell me what's happened and why this would suddenly spring up after all these years?

Parse error: syntax error, unexpected '"' in /home/talkukco/public_html/warksonline/forum/showthread.php on line 1345 - being displayed

Greatly appreciated if anyone can help

this is what I have there

	unset($userarray, $userid, $username);

	$parent_postids = fetch_post_parentlist($curpostid);
	if (!$parent_postids)
	{
		$currentdepth = 0;
	}
	else
	{
		$currentdepth = sizeof(explode(',', $parent_postids));
	}

	sort_threaded_posts();
