我有一个数组,
$arr=(
[0] => Array
(
[groupid] => 1
[groupname] => Red
[members] => Array
(
[0] => Array
(
[mid] => 9
[name] => Anith
)
[1] => Array
(
[mid] => 11
[name] => Aravind
)
[2] => Array
(
[mid] => 10
[name] => Lekshmi
)
)
)
[1] => Array
(
[groupid] => 2
[groupname] => Blue
[members] => Array
(
[0] => Array
(
[mid] => 6
[name] => Yamuna
)
[1] => Array
(
[mid] => 2
[name] => Kamala K
)
[2] => Array
(
[mid] => 13
[name] => Sooraj K
)
)
)
我想检查数组中的[mid] => 2
..如果它存在
我想删除它(即取消设置数组)-----
[1] => Array
(
[mid] => 2
[name] => Kamala K
)
;;;
例如: - unset($arr[1]['members'][2];
答案 0 :(得分:4)
这应该可以解决问题
foreach ($arr as $group => $subarray) {
foreach ($subarray['members'] as $k => $v) {
if ($v['mid'] == 2) {
unset($arr[$group]['members'][$k]);
break;
}
}
}
var_dump($arr);
如果你想变得狡猾,你可以这样做:
// note: requires PHP >= 5.3
foreach ($arr as $key => &$value) {
$value['members'] = array_filter(
$value['members'],
function($member) {
return $member['mid'] != 2;
}
);
}
var_dump($arr);
