Buenas noches Tengo la siguiente consulta en phalcon y me arroja este error:

Parse error:syntax error, unexpected ‘”pr_employees.doctype_id, pr_e’ (T_CONSTANT_ENCAPSED_STRING) in /var/www/html/apiabacus/app/controllers/EmployeesController.php on line 27

codigo:

public function getAction() { $ id = $ this->request->getQuery(‘id’); $ fieldString = ”; $ joinString = ”; $ whereString = ”; $ sql=”; $ params = [‘:id’ => $ id];

  $  sql = "SELECT" "pr_employees.doctype_id, pr_employees.id, pr_employees.last_name,    pr_employees.last_name2, pr_employees.name, pr_employees.bod, pr_employees.gender,    pr_employees.address, pr_employees.phone, pr_employees.cell_phone, pr_employees.email,    pr_employees.city_birth, pr_employees.city_life, pr_employees.cost_center_id,    pr_employees.cesantias_id, pr_employees.afp_id, pr_employees.eps_id, pr_employees.ccf_id,    pr_employeespr_cost_centers.provision_group_id, pr_employees.bank, pr_employees.bank_account,    pr_employees.relationship_id, pr_employees.status, pr_employees.doa, pr_employees.dor,    pr_cities.city, c.city,    pr_cost_centers.cost_center,    pr_relationship.relationship,    pr_funds.fund, f.fund, u.fund, n.fund,    pr_provision_groups.provision_group";   $  sql .= " FROM pr_employees";   $  sql .= " INNER JOIN pr_relationship  ON pr_relationship.id = pr_employees.relationship_id ";   $  sql .= " INNER JOIN pr_cities ON pr_cities.id = pr_employees.city_birth ".  $  joinString;   $  sql .= " INNER JOIN pr_cities AS c ON pr_employees.city_life = c.id ".  $  joinString;   $  sql .= " INNER JOIN pr_cost_centers ON pr_cost_centers.id = pr_employees.cost_center_id ".  $  joinString;   $  sql .= " INNER JOIN pr_funds ON pr_employees.cesantias_id = pr_funds.id ".  $  joinString;   $  sql .= " INNER JOIN pr_funds AS f ON pr_employees.afp_id = f.id ".  $  joinString;   $  sql .= " INNER JOIN pr_funds AS u ON pr_employees.eps_id = u.id ".  $  joinString;   $  sql .= " INNER JOIN pr_funds AS n ON pr_employees.ccf_id = n.id ".  $  joinString;   $  sql .= " INNER JOIN pr_provision_groups ON pr_provision_groups.id = pr_employees.provision_group_id ".  $  joinString;   $  sql .= " WHERE pr_employees.id = 35523859 ". $  whereString;   $  result = $  this->db->fetchAll($  sql,  Phalcon\Db::FETCH_ASSOC, $  params);   $  this->jsonResponseAction(['data' => $  result]); } 

y la verdad no encuentro que e echo mal, gracias por su ayuda.
