if ( empty(trim($str)) ) {
	echo "BUG";
} else {
	echo "WORKS";
}

Dont really need all the echo's since it never gets past a syntax check for the empty(trim()) part. I have to assume its a bug since logically, it shouldnt give a parser error.

Parse error: parse error, expecting `T_VARIABLE' or `'$'' in /website/main/test.php on line 2

As per the documentation empty() has no meaning for anything other than a variable.  You can't pass it an expression.
