问题描述
我有一个应该分割我的数组分成更小，分布均匀阵列功能，但它似乎沿途要重复我的数据。如果有人可以帮助我走出那简直太好了。
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.
下面是原始数组：

下面是其目的是要分裂阵列的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;
}
下面是分裂的结果（它在某种程度上复制原始数组中的物品放入更小的数组）：
Here's the result of the split (it somehow duplicates items from the original array into the smaller arrays):

^^正如你可以看到有由新创建的小阵列中的原始数组重复。
^^ As you can see there are duplicates from the original array in the newly created smaller arrays.
我以为我可以用一个多维的删除重复功能删除重复的，但没有奏效。我猜我的问题是在array_split功能。
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？ ：）
推荐答案
编辑：有 array_chunk ，该不会只是
好吧，我不喜欢调试，所以我写了一个版本的 array_reduce ：
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
Array
(
[0] => Array
(
[0] => 1
[1] => 2
)
[1] => Array
(
[0] => 3
[1] => 4
)
[2] => Array
(
[0] => 5
)
)
