我正在使用PHP，并且有一个看起来像这样的数组数组:

Question

Array
(
    [1] => Array
        (
            [1] => Title
            [2] => Exam1
        )
    [2] => Array
        (
            [1] => class_name
            [2] => date
            [3] => start_time
            [4] => finish_time
            [5] => subject
            [6] => exam_details
        )
    [3] => Array
        (
            [1] => 10
            [2] => 2014-03-08
            [3] => 2014-03-26 08:44:15
            [4] => 2014-03-26 08:44:15
            [5] => Maths
            [6] => Extra comments
        )
    [4] => Array
        (
            [1] => 10
            [2] => 2014-03-07
            [3] => 2014-03-26 08:44:15
            [4] => 2014-03-26 08:44:15
            [5] => Eng
            [6] => Extra comments
        )
    [5] => Array
        (
            [1] => 10
            [2] => 2014-03-06
            [3] => 2014-03-26 08:44:15
            [4] => 2014-03-26 08:44:15
            [5] => Science
            [6] => Extra comments
        )
    [6] => Array
        (
            [1] => Title
            [2] => Exam2
        )
    [7] => Array
        (
            [1] => class_name
            [2] => date
            [3] => start_time
            [4] => finish_time
            [5] => subject
            [6] => exam_details
        )
    [8] => Array
        (
            [1] => 10
            [2] => 2014-03-08
            [3] => 2014-03-26 08:44:15
            [4] => 2014-03-26 08:44:15
            [5] => Maths
            [6] => Extra comments
        )
    [9] => Array
        (
            [1] => 10
            [2] => 2014-03-07
            [3] => 2014-03-26 08:44:15
            [4] => 2014-03-26 08:44:15
            [5] => Eng
            [6] => Extra comments
        )
    [10] => Array
        (
            [1] => 10
            [2] => 2014-03-06
            [3] => 2014-03-26 08:44:15
            [4] => 2014-03-26 08:44:15
            [5] => Science
            [6] => Extra comments
        )
)

如您所见，第一个数组和第二个数组中有一些标题和标题名称定义字段名称，其他三个是该字段的值，我想使用考试标题划分数组，像这样

[Exam1] =>Array
(
    [2] => Array
        (
            [class_name] => 10
            [date] => 2014-03-08
            [start_time] => 2014-03-26 08:44:15
            [finish_time] => 2014-03-26 08:44:15
            [subject] => Maths
            [exam_details] => Extra comments
        )
    [3] => Array
        (
            [class_name] => 10
            [date] => 2014-03-07
            [start_time] => 2014-03-26 08:44:15
            [finish_time] => 2014-03-26 08:44:15
            [subject] => Eng
            [exam_details] => Extra comments
        )
    [4] => Array
        (
            [class_name] => 10
            [date] => 2014-03-06
            [start_time] => 2014-03-26 08:44:15
            [finish_time] => 2014-03-26 08:44:15
            [subject] => Science
            [exam_details] => Extra comments
        )
)
[Exam2] =>Array
(
    [7] => Array
        (
            [class_name] => 10
            [date] => 2014-03-08
            [start_time] => 2014-03-26 08:44:15
            [finish_time] => 2014-03-26 08:44:15
            [subject] => Maths
            [exam_details] => Extra comments
        )
    [8] => Array
        (
            [class_name] => 10
            [date] => 2014-03-07
            [start_time] => 2014-03-26 08:44:15
            [finish_time] => 2014-03-26 08:44:15
            [subject] => Eng
            [exam_details] => Extra comments
        )
    [9] => Array
        (
            [class_name] => 10
            [date] => 2014-03-06
            [start_time] => 2014-03-26 08:44:15
            [finish_time] => 2014-03-26 08:44:15
            [subject] => Science
            [exam_details] => Extra comments
        )
)

Answer 1

好的，这是逻辑，我还没有测试过。

将结果保存到新数组中，例如$array。

// Generate result set
$i=0;
foreach($array as $arr) {
    if(count($arr)==2) {
        $i++;
        $newarray[$i] = array();
    } else {
        foreach($arr as $single){
            array_push($newarray[$i], $single);
        }
    }
}
// New result array
foreach($newarray as $a_new) {
    print_r($a_new);
}

Answer 2

Ok

试试这种方式:)

$badArray = array();
$goodArray = array();
$i = FALSE;
$k = FALSE;
foreach($badArray as $key=>$value){
    if( !empty($value[1] && $value[1] === 'Title')){
        $i = TRUE;
        $k = $value[2];
        $goodArray[$value[2]] = [];
        continue;
    }
    if( $i == TRUE){
        $i = FALSE;
        $keysArray = $value;
        continue;
    }
    $goodArray[$k][] = array_combine(array_values($keysArray), array_values($value));
}

echo "<pre>";
var_dump($goodArray);

我想我得到了正确的答案，但最好检查一下:)

Answer 3

// split array into small chunks
$arrChunked = array_chunk($myArray, 5);
$formattedArray = array();
// loop through array chunk
foreach ($arrChunked as $arr)
{
    // get titles
    $title = current($arr);
    $title = $title[2];
    // get key from this title
    $key = key($arr);
    // remove title from array
    unset($arr[$key]);
    // get the array without titles and append to new formatted array
    $formattedArray[$title] = $arr;
}
