我有一个这样的多维数组：
Array
(
[Members] => Array
(
[0] => Array
(
[id] => 1
[name] => John
)
[1] => Array
(
[id] => 3
[name] => Mark
)
[2] => Array
(
[id] => 4
[name] => Paul
)
[3] => Array
(
[id] => 2
[name] => Robert
)
)
)
是否可以将 name = Paul 的位置更改为数组顶部？
输出应为
Array
(
[Members] => Array
(
[0] => Array
(
[id] => 4
[name] => Paul
)
[1] => Array
(
[id] => 1
[name] => John
)
[2] => Array
(
[id] => 3
[name] => Mark
)
[3] => Array
(
[id] => 2
[name] => Robert
)
)
)
谢谢！
你可以先搜索保罗，然后为保罗创建一个临时持有者，在原始数组中取消设置 paul，然后再次在其中取消移动 Paul，这样他就会出现在顶部：
$array = [
'Members' => [
['id' => 1, 'name' => 'John'],
['id' => 3, 'name' => 'Mark'],
['id' => 4, 'name' => 'Paul'],
['id' => 2, 'name' => 'Robert'],
]
];
$name = 'Paul';
$temp = [];
foreach ($array['Members'] as $k => $value) {
if($name == $value['name']) { // search for paul, if found
$temp = $value; // put him inside temporarily
unset($array['Members'][$k]); // remove paul
}
}
array_unshift($array['Members'], $temp); // then put paul up top
echo '<pre>';
print_r($array);
简单输出
