try this ** **Example

$or = array(
        'PersonalInformation.first_name' => $this->request->data['User']['first_name'],
        'PersonalInformation.last_name' => $this->request->data['User']['last_name'],
        'PersonalInformation.primary_phone' => $this->request->data['User']['primary_phone'],
        'PersonalInformation.dob' => $this->request->data['User']['dob'],

 $or = array_filter($or);

    $condition = array(
        'User.role' => array('U', 'P'),
        'User.user_status' => array('active', 'lead', 'inactive'),
        'OR' => $or
    );
