php - 如何在 PHP 中找到特定索引后将数组分成两部分？

Question

我有一个以特定索引开头的数组，第一个索引总是 43，之后我有信息，我想在找到值 products 但不是products 的值始终是索引 64，每次都会不同。

所以我试着用这个来找到值(value)产品所在的索引

$index = array_search('products', $data);

这样我就可以找到我想将数组拆分为 2 的索引，但我不知道如何，我尝试使用 array_chunk 但我无法让它工作

这是我的原始数组:

Array
(
    [43] => 1234
    [44] => 001
    [45] => 100
    [46] => 0
    [47] => 0
    [48] => 2
    [49] => 
    [50] => 1234
    [51] => 001
    [52] => 100
    [53] => 0
    [54] => 0
    [55] => 2
    [56] => 
    [57] => 
    [58] => 
    [59] => 
    [60] => 
    [61] => 0
    [62] => 1
    [63] => 
    [64] => products
    [65] => 1234
    [66] => 001
    [67] => 100
    [68] => 0
    [69] => 0
    [70] => 2
    [71] => 
    [72] => 1234
    [73] => 001
    [74] => 100
    [75] => 0
    [76] => 0
    [77] => 2
    [78] => 
    [79] => 
    [80] => 
    [81] => 
    [82] => 
    [83] => 0
    [84] => 1
)

我想要这样的东西:

Array
(
    [43] => 1234
    [44] => 001
    [45] => 100
    [46] => 0
    [47] => 0
    [48] => 2
    [49] => 
    [50] => 1234
    [51] => 001
    [52] => 100
    [53] => 0
    [54] => 0
    [55] => 2
    [56] => 
    [57] => 
    [58] => 
    [59] => 
    [60] => 
    [61] => 0
    [62] => 1
    [63] =>
)

Array
( 
    [65] => 1234
    [66] => 001
    [67] => 100
    [68] => 0
    [69] => 0
    [70] => 2
    [71] => 
    [72] => 1234
    [73] => 001
    [74] => 100
    [75] => 0
    [76] => 0
    [77] => 2
    [78] => 
    [79] => 
    [80] => 
    [81] => 
    [82] => 
    [83] => 0
    [84] => 1
)

同样没有值 products 的索引，您是否知道我可以使用什么函数来实现此目的或其他方法？希望您能帮帮我，谢谢。

几乎，array_chunk()制作多个片段而不是您想通过给定键将数组切片分成两部分，这可以用array_slice()来完成

$split = array_search('products', $data);

print_r(array_slice($data, 0, $split))   // first part
print_r(array_slice($data, $split + 1)); // second part
