php数组里面怎样遍历出每个数组里面的id值啊，谢谢大家！

Array

[0] => Array
(
[id] => 0
[name] => 未分组
[count] => 0
)

[1] => Array
(
[id] => 1
[name] => 黑名单
[count] => 0
)

[2] => Array
(
[id] => 2
[name] => 星标组
[count] => 0
)

)

Answer 1

<?php
$arr = array
(
'0' => array
(
'id' => '0',
'name' => '未分组',
'count' => '0'
),

'1' => array
(
'id' => '1',
'name' => '黑名单',
'count' => '0'
),

'2' => array
(
'id' => '2',
'name' => '星标组',
'count' => '0'
)

);

foreach( $arr as $v1 )
{
echo $v1["id"]."<br>";

}

?>
已通过调试成功！

用foreach循环呀，假如你的数组是$arr，那就这样：
foreach($arr as $k=>$v){
echo $v['id'];//输出数组中的id

}
