PHP String “0″ or empty issue

Given example an empty value of array like:

Model_x Object ( 
	[_is_new:protected] => [_frozen:protected] => [_data:protected] => 
	Array ( 
		[track_value] => 
		)
	)

When processed the array and $value = $x->track_value

	if($value == 1){
		$returnValue = "Automatic";
	}else if($value == 0){
		$returnValue = "Manuals";
	}else{
		$returnValue = "Undefined";
	}

Output value will be always “Manuals”.

To fix this issue, add “” into the “1″ or “0″
