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>' ; print_r( $data );
|
结果为:
1
|
Tom
|
示例2:
1
2
3
|
$conn = $this ->getDoctrine()->getConnection();
$data = $conn ->fetchArray( "SELECT name, color FROM test" );
echo '<pre>' ; print_r( $data );
|
结果为:
1
2
3
4
5
|
Array
(
[0]=>Tom
[1]=>blue
)
|
示例3:
1
2
3
|
$conn = $this ->getDoctrine()->getConnection();
$data = $conn ->fetchAssoc( "SELECT name, color FROM test" );
echo '<pre>' ; print_r( $data );
|
结果为:
1
2
3
4
5
|
Array
(
[name]=>Tom
[color]=>blue
)
|
示例4:
1
2
3
|
$conn = $this ->getDoctrine()->getConnection();
$data = $conn ->fetchAll( "SELECT name, color FROM test" );
echo '<pre>' ; print_r( $data );
|
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
)
)
|
希望本文所述对大家基于Symfony框架的PHP程序设计有所帮助。
