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 = $conn->fetchcolumn("SELECT name, color FROM test");echo '<pre>'; print_r($data);
结果为:
示例2:
$conn = $this->getDoctrine()->getConnection();$data = $conn->fetchArray("SELECT name, color FROM test");echo '<pre>'; print_r($data);
结果为:
Array( [0]=>Tom [1]=>blue)
示例3:
$conn = $this->getDoctrine()->getConnection();$data = $conn->fetchAssoc("SELECT name, color FROM test");echo '<pre>'; print_r($data);
结果为:
Array( [name]=>Tom [color]=>blue)
示例4:
$conn = $this->getDoctrine()->getConnection();$data = $conn->fetchAll("SELECT name, color FROM test");echo '<pre>'; print_r($data);
结果为:
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。
