我有一个函数应该将我的数组拆分成更小,均匀分布的数组,但是它似乎在重复我的数据。如果有人能帮助我,那就太好了。
这是原始数组:

这是用于拆分数组的php函数:
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重复到较小的数组中):

^^正如您所看到的,在新创建的较小数组中,原始数组中存在重复项。
我以为我可以使用多维删除重复功能删除重复项,但这不起作用。我猜我的问题出在array_split函数中。
有什么建议吗? :)
答案 0 :(得分:8)
编辑:有array_chunk,就是这样。
好吧,我不想调试,所以我用array_reduce编写了一个版本:
$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()));
给出
Array
(
[0] => Array
(
[0] => 1
[1] => 2
)
[1] => Array
(
[0] => 3
[1] => 4
)

)
)

$sections = array_chunk(array('k', 'l', 'm', 'n', 'o'), 2);
答案 2 :(得分:1)
在我看来,其余项目的分布过于复杂。
如果您知道丢失了多少项($Remainder
),为什么不生成剩余切片并使用array_pop()
弹出项目,直到它为空?
顺便说一句,您也可以对整个数组使用该过程。

function split_array(&$array, $slices) {
$result = array();
$l = count($array)-1;
for ($i=0; $i<=$l; $i++) {
if ($i == 0 || $i % $slices == 0) $tmp = array();
$tmp[] = $array[$i];
if ($i == $l || $i % $slices == 1) $result[] = $tmp;
}
return $result;

array_chunk
不会均匀填充数组,除非元素总数可以被所需的块数整除;最后一个块可能比第一个块小得多(例如,如果你有七个元素并且你分成三个块,你将得到包含三个,三个和一个元素的数组)。
以下实现将尝试平滑这一点,以便在您追求的数据大小更均匀时,例如如果你有七个元素,你将得到包含三个,两个和两个元素的块数组。它仍然没有,但它更均匀。如果计数可以被列数整除,则可以回退到使用array_chunk
,因为这样会更快(特别是如果你有大型数组)。
<?php
function array_group($array, $num)
{
$num = (int) $num;
if ($num < 1) {
throw new \InvalidArgumentException('At least one group must be returned.');
}
$count = count($array);
if ($count && $count % $num === 0) {
return array_chunk($array, $count / $num);
}
$groups = [];
$offset = 0;
do {
$length = ceil(($count - $offset) / $num);
$groups[] = array_slice($array, $offset, $length);
$offset += $length;
} while (--$num);
return $groups;
}
print_r(array_chunk(array(1, 2, 3, 4, 5, 6, 7), 3));

尝试这个简单的用法。当它找到空字符串时,它会将数组拆分为两个数组。一个从开始到空字符串索引。其他从空字符串索引到最后一个。
注意:两者都不包含Emty字符串。它仅用于条件检查。
$column[] = "id";
$column[] = "name";
$column[] = "email";
$column[] = "password";
$column[] = "";
$column[] = "uid";
$column[] = "uname";
$column[] = "mname";
$column[] = "lname";
$column[] = "city";
$column[] = "country";
$column[] = "zip";
$column[] = "cell";
$column[] = "address";
split_array($column);
function split_array($column)
{
$total = count($column);
$num = array_search('',$column);
$split = $total - $num ;
$outer_sql = array_slice( $column , - ($split) + 1);
array_splice($column , $num);
echo "<pre>";
print_r($outer_sql);
echo "</pre>";
echo "<pre>";
print_r($column);
echo "</pre>";
}

将php数组分成两个相等的部分是一种简单的方法。 并且您可以使用foreach easity
获取两个数组的所有元素和值list($firstarray, $secondarray) = array_chunk($vorstand_two_column, ceil(count($all_array_contents) / 2));
foreach($firstarray as $fa) {
.... Code ....
}
foreach($secondarray as $sa) {
.... Code ....
}
