Question

I’ve this small code, I know I receive fine from the database because I made some print_r and work fine:

//build query SQL         
$query = $this ->select() 
    ->where('numBedrooms=?',$numBedrooms) 
    ->where('type=?',$type)
    ->where('state=?',$state)
    ->limit(8);//8 rows, with an offset of $recent_page*8-8
//execute query SQL
$rows=$this->fetchAll($query);
//encode json
$var= json_encode($rows);//-------->var is empty always!!

Answer 1

If fetchAll() is returning an object like you say it is, then it would be wise to first convert this to an array and then to pass it to json_encode. I do not believe json_encode work’s with objects.
