使用条件合并数组中的元素

Question

如果StartingDateTime具有公共值并且在TWHour和TEHour创建另一个数组以及合并数组的相应值，我正在尝试合并数组中的元素

请注意，可以有更多具有相同StartingDateTime的数组。

以下是$items数组的摘录：

Array

Answer 1

我认为它会对你有所帮助。

试试这个：

$arr = array(
    array(
            'StartingDateTime' => "2016-06-28",
            'TWHour' => "03:00:00",
            'TEHour' => "05:00:00",
            'NoOfHoursWorked' => 10,
            'NoOfHoursRest' => 14,
            'Comments' => "want",
            'NoOfHoursRestAny24HR' => 14,
            'NoOfHoursRestAny7Day' => 98
        ), 
    Array
        (
            'StartingDateTime' => "2016-06-28",
            'TWHour' => "13:30:00",
            'TEHour' => "23:30:00",
            'NoOfHoursWorked' => 10,
            'NoOfHoursRest' => 14,
            'Comments' => "want",
            'NoOfHoursRestAny24HR' => 14,
            'NoOfHoursRestAny7Day' => 98
        )
    );

$results = array();
array_map(function($a, $b) use (&$results) {    
    $tmp = array($a['TWHour'], $b['TWHour']);
    $a['TWHour'] = $b['TWHour'] = $tmp; 

    $tmp = array($a['TEHour'], $b['TEHour']);
    $a['TEHour'] = $b['TEHour'] = $tmp; 

    $results += array_merge($a,$b);
}, array($arr[0]),array($arr[1]));

$ results 是最终结果。
