下面是我在 Zend 2.0 中创建查询的方式

$getVenues = $this->tableGateway->select(function (Select $select) {
    $select->where->greaterThanOrEqualTo('lat', (float) $lat_min);
    $select->where->greaterThanOrEqualTo('lng', (float) $lng_min);
    $select->where->lessThanOrEqualTo('lat', (float) $lat_max);
    $select->where->lessThanOrEqualTo('lng', (float) $lng_max);
});

输出以下查询：

SELECT `venues`.* FROM `venues` WHERE `lat` >= :where1 AND `lng` >= :where2 AND `lat` <= :where3 AND `lng` <= :where4

填写每个参数:where*后，它看起来像这样：

SELECT `venues`.* FROM `venues` WHERE `lat` >= 39.730387437667 AND `lng` >= -86.332592054637 AND `lat` <= 40.020242510131 AND `lng` <= -85.954901904578

在 phpMyAdmin 中执行原始 SQL 查询返回正确的结果，但我的 Zend 2.0 查询返回 0 行。

下面是var_dumpZend 的查询结果集：

object(Zend\Db\ResultSet\ResultSet)#227 (8) {
  ["allowedReturnTypes":protected]=>
  array(2) {
    [0]=>
    string(11) "arrayobject"
    [1]=>
    string(5) "array"
  }
  ["arrayObjectPrototype":protected]=>
  object(Application\Model\Venue)#208 (12) {

    }
