将数组拆分为两个数组，其值大于和小于给定的针PHP

I do not want to use a loop (unless there is no other way). I know how to do this using foreach loop and building 2 arrays but I was wondering if built in function exists in PHP.

我不想使用循环(除非没有其他方法)。我知道如何使用foreach循环和构建2个数组,但我想知道PHP中是否存在内置函数。

$arr = array(1 => 0.1, 2 => 0.20, 3 => 0.40, 4 => 0.60);

I want to get the resulting two arrays after the function call:

我想在函数调用后获得结果的两个数组:

$twoArrays = split_arrays($arr, 0.3);

$twoArrays would hold the values:

$ twoArrays将保存值:

array(
  0 => array(1 => 0.1, 2 => 0.20), 
  1 => array(3 => 0.40, 4 => 0.60)
);

Basically I want 1 array to hold all values less than 0.3 and another greater than 0.3.

基本上我想要1个数组来保存小于0.3的所有值和另一个大于0.3的值。

With loop I can do it, is there a PHP built in function?

有了循环,我可以做到,是否有PHP内置函数?

NOTE: I need to keep the keys as it is.

注意:我需要保持按键原样。

You could use array_filter() twice:

您可以使用array_filter()两次:

$bottom = array_filter($myArray, function($val){return ($val<=0.3)});

$top = array_filter($myArray, function($val){return ($val>0.3)});
