本文实例讲述了Symfony2实现从数据库获取数据的方法。分享给大家供大家参考,具体如下:

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 = $conn->fetchcolumn("SELECT name, color FROM test");
echo '<pre class="brush:php;toolbar:false">'; print_r($data);

Copy after login

结果为:

Tom

Copy after login

示例2:

$conn = $this->getDoctrine()->getConnection();
$data = $conn->fetchArray("SELECT name, color FROM test");
echo '<pre class="brush:php;toolbar:false">'; print_r($data);

Copy after login

结果为:

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

Copy after login

示例3:

$conn = $this->getDoctrine()->getConnection();
$data = $conn->fetchAssoc("SELECT name, color FROM test");
echo '<pre class="brush:php;toolbar:false">'; print_r($data);

Copy after login

结果为:

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

Copy after login

示例4:

$conn = $this->getDoctrine()->getConnection();
$data = $conn->fetchAll("SELECT name, color FROM test");
echo '<pre class="brush:php;toolbar:false">'; print_r($data);

Copy after login

结果为:

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

Copy after login

希望本文所述对大家基于Symfony框架的PHP程序设计有所帮助。
