问题描述
我有一个函数应该将我的数组拆分成更小的、均匀分布的数组，但是它似乎在复制我的数据.如果有人可以帮助我，那就太好了.
I have a function that is supposed to split my array into smaller, evenly distributed arrays, however it seems to be duplicating my data along the way. If anyone can help me out that'd be great.
这是原始数组:

这是用于拆分数组的 php 函数:
Here's the php function which is meant to split the array:
function split_array($array, $slices) {
$perGroup = floor(count($array) / $slices);
$Remainder = count($array) % $slices ;
$slicesArray = array();
$i = 0;
while( $i < $slices ) {
$slicesArray[$i] = array_slice($array, $i * $perGroup, $perGroup);
$i++;
}
if ( $i == $slices ) {
if ($Remainder > 0 && $Remainder < $slices) {
$z = $i * $perGroup +1;
$x = 0;
while ($x < $Remainder) {
$slicesRemainderArray = array_slice($array, $z, $Remainder+$x);
$remainderItems = array_merge($slicesArray[$x],$slicesRemainderArray);
$slicesArray[$x] = $remainderItems;
$x++;
$z++;
}
}
};
return $slicesArray;
}
这是拆分的结果(它以某种方式将原始数组中的项目复制到较小的数组中):
Here's the result of the split (it somehow duplicates items from the original array into the smaller arrays):

^^ 如您所见，在新创建的较小数组中，原始数组中有重复项.
^^ As you can see there are duplicates from the original array in the newly created smaller arrays.
我以为我可以使用多维删除重复函数来删除重复项，但这不起作用.我猜我的问题出在 array_split 函数中.
I thought I could remove the duplicates using a multi-dimensional remove duplicate function but that didn't work. I'm guessing my problem is in the array_split function.
有什么建议吗?:)
推荐答案
有 array_chunk，其中就是这样.
好吧，我不想调试，所以我用array_reduce写了一个版本:>
Well, I didn't feel like debugging, so I wrote a version with array_reduce:
$pergroup = 2;
$redfunc = function ($partial, $elem) use ($pergroup) {
$groupCount = count($partial);
if ($groupCount == 0 || count(end($partial)) == $pergroup)
$partial[] = array($elem);
else
$partial[$groupCount-1][] = $elem;
return $partial;
};
$arr = array(1,2,3,4,5);
print_r(array_reduce($arr, $redfunc, array()));
给予
Array
(
[0] => Array
(
[0] => 1
[1] => 2
)
[1] => Array
(
[0] => 3
[1] => 4
)
[2] => Array
(
[0] => 5
)
)
