PHP - Is It Possible To "redirect" Htdocs To Another Folder?

I am getting these errors . This is my complete HTML page.

Everything seems to work fine but when i retweet a message these error show up.

Here is my tweet.php and the errors are at line 32 and 41.

Previously there was an error at line 24:

It was like this:

'.((!empty($tweet->retweetMsg) && $tweet->tweetID === $retweet['tweetID'] or $tweet->retweetID > 0) ? '

I changed it to this and the error went away

'.((isset($retweet['retweetID']) ? $retweet['retweetID'] === $tweet->retweetID OR $tweet->retweetID > 0 : '') ? '

Maybe this could help!

I will really appreciate any suggestion coming my way!
