Question

我有一个mysql查询，它会吐出以下内容：

Array
(
    [0] => stdClass Object
        (
            [bid] => 18
            [name] => Cafe Domingo
            [imageurl] => sp_domingo.gif
            [clickurl] => #
        )

    [1] => stdClass Object
        (
            [bid] => 19
            [name] => Industrial Sweeping Services

        )

    [2] => stdClass Object

            [clickurl] => http://www.baycorporatecatering.com.au/
        )

    [5] => stdClass Object
        (
            [bid] => 24
            [name] => Steve Wilby Transport
            [imageurl] => sp_swilky.gif

            [imageurl] => sp_cody.gif
            [clickurl] => #
        )

    [7] => stdClass Object
        (
            [bid] => 21
            [name] => Matthew Davis Australia Pty Ltd
            [imageurl] => sp_matthewdavis.gif
            [clickurl] => http://www.matthewdavis.com.au/
        )

    [8] => stdClass Object
        (
            [bid] => 25
            [name] => Tom the Lumberjack
            [imageurl] => sp_tom.gif
            [clickurl] => http://www.redwoodgardens.com.au/
        )

    [9] => stdClass Object
        (
            [bid] => 16
            [name] => Bendigo Bank
            [imageurl] => sp_bb.gif
            [clickurl] => http://www.bendigobank.com.au/
        )

    [10] => stdClass Object
        (
            [bid] => 14
            [name] => 360South Pty Ltd
            [imageurl] => sp_360south.gif
            [clickurl] => http://www.360south.com.au/
        )

    [11] => stdClass Object
        (
            [bid] => 23
            [name] => Redwood Gardens Chinese Restaurant
            [imageurl] => sp_redwood.gif
            [clickurl] => http://www.redwoodgardens.com.au/
        )

)

然后可以将该数组拆分为4个数组吗？每个数组中的项目数量相等（尽可能最好），但随着更多信息被放入dbase，它们可以是动态的。所以如果数量不均匀，最后一个数组的数量会减少？

如果这有意义吗？

Answer 1

当然可以！以下代码将执行此操作，将结果拆分为您指定的切片数。

function split_array($array, $slices) {
  $perSlice = floor(count($array) / $slices);
  $sliceExtra = count($array) % $slices;

  $slicesArray = array();
  $offset = 0;

  for($i = 0; $i < $slices; $i++) {
    $extra = (($sliceExtra--) > 0) ? 1 : 0;
    $slicesArray[] = array_slice($array, $offset, $perSlice + $extra);
    $offset += $perSlice + $extra;
  }

  return $slicesArray;
}

$slices = split_array($mysqlResult,4);

编辑：编辑以制作更均匀的切片。

Answer 2

我认为这有效

$splitArray = array_chunk( $sourceArray, ceil( count( $sourceArray ) / 4 ) );

将MYSQL结果拆分为4个数组
