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:
1 2 3 | $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:
示例2:
1 2 3 | $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:
1 2 3 4 5 | Array
(
[0]=>Tom
[1]=>blue
)
|
Copy after login
示例3:
1 2 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:
1 2 3 4 5 | Array
(
[name]=>Tom
[color]=>blue
)
|
Copy after login
示例4:
1 2 3 | $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:
1 2 3 4 5 6 7 8 9 10 11 12 13 | 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。
