仅将某些数组键合并并分组到新数组中

arrays php

我有一个 foreach 循环 if 语句,该语句根据字符串包含的内容创建数组。

foreach ($dataArray2 as $item) {
    $items = [];
    if(strpos($item, 'your date is') !== false)
    {
        //Converting 22052018 to 2018-05-22
        $month_words = ["may"];
        $month_numbers   = ["05"];
        $item = str_replace($month_words, $month_numbers, $item);
        $item = preg_replace('/[^0-9]/', '', $item);
        $insertion = "-";
        $index = 2;
        $index2 = 5;
        $item = substr_replace($item, $insertion, $index, 0);
        $item = substr_replace($item, $insertion, $index2, 0);
        $time = strtotime($item);
        $date = date('Y-m-d', $time);

        $items['date']= $date;

    } else if (strpos($item, 'hat') !== false) {

        $item = str_replace('.', '', $item);
        $items['hat'] = $item;

    } else {

        $items['tshirt'] = $item;

    }

    $dataArr[] = array_filter($items);

}

echo '<pre>';
print_r($dataArr);
echo '</pre>';

数组如下:

    [0] => Array
        (
            [date] => 2018-05-22
        )

    [1] => Array
        (
            [hat] => blue
        )

    [2] => Array
        (
            [tshirt] =>  white
        )

    [3] => Array
        (
            [hat] =>  black 
        )

    [4] => Array
        (
            [tshirt] => cyan
        )

    [5] => Array
        (
            [date] => 2018-05-21
        )

    [6] => Array
        (
            [hat] =>  red
        )

    [7] => Array
        (
            [tshirt] => blue
        )

我需要它看起来像:

[0] => Array
    (
        [0] => Array (
                [date] => 2018-05-22,
                [hat] => blue,
                [tshirt] =>  white,
                [hat] =>  black,
                [tshirt] =>  cyan
            )

        [1] => Array
            (
                [date] => 2018-05-21
                [hat] => red,
                [tshirt] =>  blue,
            )
)

编辑: var_export 输入数组的格式:

array (
  0 => 'your date is 22 may 2018, Tuesday.',
  1 => 'hat: blue.',
  2 => 'tshirt: white',
  3 => 'hat: black.',
  4 => 'tshirt: cyan',
  5 => 'your date is 21 may 2018, Tuesday.',
  6 => 'hat: red.',
  7 => 'tshirt: blue',

编辑2:如何分解内部数组 content 分为x2块,如下所示:

Array
(
    [0] => Array
        (
            [date] => 2018-05-22
            [content] => Array
                (
                    [0] => Array
                        (
                            [0] => blue
                            [1] => white
                        )

                    [1] => Array
                        (
                            [0] => black
                            [1] => cyan
                        )

                    [2] => Array
                        (
                            [0] => red
                            [1] => blue
                        )
                )
        )

    [1] => Array
        (
            [date] => 2018-05-21
            [content] => Array
                (
                    [0] => Array
                        (
                            [0] => blue
                            [1] => white
                        )

此方法创建一个可能的数组。
代替regex来解析日期,我使用更轻的日期()。
由于tshirt和hats是“相同的”,所以我使用相同的方法来解析它们。

$arr = array (
    0 => 'your date is 22 may 2018, Tuesday.',
    1 => 'hat: blue.',
    2 => 'tshirt: white',
    3 => 'hat: black.',
    4 => 'tshirt: cyan',
    5 => 'your date is 21 may 2018, Monday.',
    6 => 'hat: red.',
    7 => 'tshirt: blue',
);

$i =-1;
foreach($arr as $item){
    if(strpos($item, 'your date is') !== false){
        $i++;
        $res[$i]['date'] = date("Y-m-d", strtotime(str_replace("your date is ", "", $item)));
    }else{
        list($key, $val) = explode(": ", $item);
        $res[$i][$key][] = rtrim($val, ".");
    }
}


var_dump($res);

输出:

array(2) {
  [0]=>
  array(3) {
    ["date"]=>
    string(10) "2018-05-22"
    ["hat"]=>
    array(2) {
      [0]=>
      string(4) "blue"
      [1]=>
      string(5) "black"
    }
    ["tshirt"]=>
    array(2) {
      [0]=>
      string(5) "white"
      [1]=>
      string(4) "cyan"
    }
  }
  [1]=>
  array(3) {
    ["date"]=>
    string(10) "2018-05-21"
    ["hat"]=>
    array(1) {
      [0]=>
      string(3) "red"
    }
    ["tshirt"]=>
    array(1) {
      [0]=>
      string(4) "blue"
    }
  }
}

编辑我也更正了你的日期。5月21日和22日不能是星期二。
