我有一个PHP数组,如下所示:
Array{
[0] {
'id' => '0',
'title' => 'foo',
'address' => '123 Somewhere',
}
[1] {
'id' => '1',
'title' => 'bar',
'address' => '123 Nowhere',
}
[2] {
'id' => '2',
'title' => 'barfoo',
'address' => '123 Elsewhere',
}
[3] {
'id' => '3',
'title' => 'foobar',
'address' => '123 Whereabouts',
}
}
我想通过嵌套数组中的'title'键对其进行排序,如下所示:
Array{
[1] {
'id' => '1',
'title' => 'bar',
'address' => '123 Nowhere',
}
[2] {
'id' => '2',
'title' => 'barfoo',
'address' => …我的阵列:
$MY_ARRAY =
Array
(
[0] => Array
(
[0] => 2861
[1] => Array
(
[start_month] => 6
[start_year] => 1970
[end_month] => 12
[end_year] => 1990
[experience_info] => "Practically a random string"
)
)
)
我希望$MY_ARRAY通过内部内容对直接孩子进行排序,理想情况是以start_year,start_month,end_year,end_month的顺序排列.我想我可以用array_multisort()某种方式,但我不知道如何.有谁知道如何处理这个？
谢谢.
编辑:当它出现时,解决方案很简单,我不知道的是,在回调比较函数的比较中你可以进入更深层次的结构 - 所以如果你的lvl-1索引比你的更深层保持不变(我的情况)那是怎么做的:)
我需要按照getNotifications函数中值'start_date'的DESC顺序对通知数组进行排序：
$posts_id_arr = getPoststIds($conn);
foreach ($posts_id_arr as $key => $val) {
$total_arr[$key] = [
'notification' => getNotifications($val['post_id'], $user_id, $conn)
];
}
$response_array = array('data' => $total_arr, 'more things' => $more_array);
echo json_encode($response_array);
现在，由于foreach循环，订单是通过邮递ID进行的。
data {
notification:
[
{
post_id: “1",
start_date: "2016-10-10 08:00:00",
},
{
post_id: “1",
start_date: "2016-10-10 12:00:00",
}
],
notification:
[
post_id: “2",
start_date: "2016-10-10 09:00:00",
},
{
post_id: “2",
start_date: "2016-10-10 13:00:00",
}
]
}
我需要是1：08:00，2：09:00，1：12:00，2：13:00
我有一个数组,需要使用键值"odbyx"进行排序
这是数组var_dump

在 PHP API 中，我有这个数组，想按 custom_price 排序，但不知道如何实现..
Array
(
[0] => Array
(
[id] => 1204
[custom_price] => 33.1500
)
[1] => Array
(
[id] => 1199
[custom_price] => 16.83
)
[2] => Array
(
[id] => 1176
[custom_price] => 16.83
)
[3] => Array
(
[id] => 1173
[custom_price] => 11.73
)
[4] => Array
(
[id] => 1170
[custom_price] => 22.5
)
)
我如何从 .. 高到低 & 从低到高 .. 按 custom_price 排序
我有一个数组如下,我想按键"攻击"的值来命令该数组.数组的第一个键是(15, 13, 18)来自数据库的某个特定项的ID,因此我不希望在对数组进行排序时更改这些键.任何帮助将不胜感激.
这是数组:
$data = array(
'15' => array(
'attack' => '45', 'defence' => '15', 'total' => '10'
),
'13' => array(
'attack' => '25', 'defence' => '15', 'total' => '10'
),
'18' => array(
'attack' => '35', 'defence' => '15', 'total' => '10'
)
);
假设我有这个数组:
$array = array(
array("id" => 7867867, "animal" => "Dog"),
array("id" => 3452342, "animal" => "Lion"),
array("id" => 1231233, "animal" => "Lion"),
array("id" => 5867867, "animal" => "Dog"),
array("id" => 1111111, "animal" => "Zeebra"),
array("id" => 2222222, "animal" => "Cat"),
array("id" => 3333333, "animal" => "Cat"),
array("id" => 4444444, "animal" => "Zeebra")
);
现在我一直在尝试做的是使用php排序函数,以便能够根据特定规则对其进行排序(不是按字母顺序)
客户希望这些信息按"Lion first,Dog second,Zeebra third,Cat 4th"排序.
像这样的东西:
$array = array(
array("id" => 3452342, "animal" => "Lion"),
array("id" => 1231233, "animal" => "Lion"),
array("id" => 7867867, "animal" => …我有一个像这样的关联数组。
