php 重置数组索引，兼容多维数组

对于一位数组，重置索引，可使用array_values();(具体用法，参考手册)

$array = array("size" => "XL", "color" => "gold");
print_r(array_values($array));

以上例程会输出：

Array
(
[0] => XL
[1] => gold
)

$post = [
0 => [
'title' => 'xxx联票',
'price' => 368.00,
'items' => [
'33' => [
'scenic_id' => 33,
'products' => [
'goods_id' => 13
]
],
'1500' => [
'scenic_id' => 1500,
'products' => [
'goods_id' => 57
]
],
],
'tickets' => 9
],
10 => [
'title' => 'zzz联票',
'price' => 500.00,
'items' => [
'157' => [
'scenic_id' => 157,
'products' => [
'goods_id' => 77
],
'attr' => [
'50' => [
'item' => '午场'
],
'55' => [
'item' => '可退'
]
]
],
'19' => [
'scenic_id' => 19,
'products' => [
'goods_id' => 87
]
]
],
'tickets' => 3
],
];
//print_r($post);
function reform_keys($array){
if(!is_array($array)){
return $array;
}
$keys = implode('', array_keys($array));
if(is_numeric($keys)){
$array = array_values($array);
}
$array = array_map('reform_keys', $array);
return $array;
};
$list = reform_keys($post);
print_r($list);

以上结果会输出:

Array
(
[0] => Array
(
[title] => xxx联票
[price] => 368
[items] => Array
(
[0] => Array
(
[scenic_id] => 33
[products] => Array
(
[goods_id] => 13
)

)

[1] => Array
(
[scenic_id] => 1500
[products] => Array
(
[goods_id] => 57
)

)

&nb
3ff0
sp; )

[tickets] => 9
)

[1] => Array
(
[title] => zzz联票
[price] => 500
[items] => Array
(
[0] => Array
(
[scenic_id] => 157
[products] => Array
(
[goods_id] => 77
)

[attr] => Array
(
[0] => Array
(
[item] => 午场
)

[1] => Array
(
[item] => 可退
)

)

)

[1] => Array
(
[scenic_id] => 19
[products] => Array
(
[goods_id] => 87
)

)

)

[tickets] => 3
)

)

里面所有层级的索引已经被重置。0,1,2.。。。。。
