You never say what $x is in the first place.
put

$x=0;

immediately before that loop.

thank you for replaying bit what about the other error :

Notice: Undefined variable: construct in E:\wamp\www\search\search.php on line 34

Ditto; except this time $construct is a string that presumably starts out empty.

$construct='';
