PHP 如何在 for 循环中操作变量以及 return 它

Question

我已经声明了一个数组 $data 并将其传递到 foreach 循环的参数中。在循环内我需要推送或合并新数组和 return 它。显然 return object 不是预期的那样。它只包含 header。我正在使用 php7.2

$data = ['code','name'];
    $submission->contributions->each(function (Contribution $contribution) use ($data) {

        $rowData = [
            $contribution->employment->employer->code,
            $contribution->employment->employee->last_name,
        ];

        $data = array_merge($data, [$rowData]);
    });
    print_f($data)

Answer 1

只需使用 foreach，您的 $data 数组就可用了：

$data = ['code','name'];
foreach($submission->contributions as $contribution) {
    $data = array_merge($data, 
        [
            $contribution->employment->employer->code,
            $contribution->employment->employee->last_name
        ]);
}
