Symfony2实现从数据库获取数据的方法小结_PHP

假设有一张表：test, 字段：name,color;
有2条记录：
Tom blue
Lily red

示例1：

$conn = $this->getDoctrine()->getConnection();
$data = $conn->fetchcolumn("SELECT name, color FROM test");
echo '
'; print_r($data);

Tom

示例2：

$conn = $this->getDoctrine()->getConnection();
$data = $conn->fetchArray("SELECT name, color FROM test");
echo '
'; print_r($data);

Array
(
  [0]=>Tom
  [1]=>blue
)

示例3：

$conn = $this->getDoctrine()->getConnection();
$data = $conn->fetchAssoc("SELECT name, color FROM test");
echo '
'; print_r($data);

Array
(
  [name]=>Tom
  [color]=>blue
)

示例4：

$conn = $this->getDoctrine()->getConnection();
$data = $conn->fetchAll("SELECT name, color FROM test");
echo '
'; print_r($data);

Array
(
  [0] => Array
    (
      [name]=>Tom
      [color]=>blue
    )
  [1] => Array
    (
      [name]=>Lily
      [color]=>red
    )
)

希望本文所述对大家基于Symfony框架的PHP程序设计有所帮助。
