PDO 的 fetch 模式功能实在是太方便了,但每次要产生想要的结果都要试太麻烦了,这里列出可能的组合。
代码如下:
<?php
$dbAdapter = new PDO("mysql:host=localhost;dbname=test", "root", "1234");
$dbAdapter->exec("SET NAMES 'utf8';");
$data = $dbAdapter->query("
SELECT id, name, method FROM category
")->fetchAll(PDO::FETCH_ASSOC);
//var_dump($data);
/*
array(
array(
'id' => '1',
'name' => 'HBO',
'method' => 'service',
),
array(
'id' => '2',
'name' => '本周新片',
'method' => 'movie',
),
array(
'id' => '3',
'name' => '热映中',
'method' => 'movie',
),
)
*/
$data = $dbAdapter->query("
SELECT name, method FROM category
")->fetchAll(PDO::FETCH_COLUMN);
//var_dump($data);
/*
array(
'HBO',
'本周新片',
'热映中',
)
*/
$data = $dbAdapter->query("
SELECT id, name, method FROM category
")->fetchAll(PDO::FETCH_UNIQUE | PDO::FETCH_ASSOC);
//var_dump($data);
/*
array(
'1' => array(
'name' => 'HBO',
'method' => 'service',
),
'2' => array(
'name' => '本周新片',
'method' => 'movie',
