'null' : $value; } unset($item['kq']); $item = array_merge($item, $kq_dict); } $output_str = json_encode($data, JSON_UNESCAPED_UNICODE); echo $output_str;使用了一个内部循环来将 kq 的值转换为字典格式。具体来说，使用了一个空的数组 $kq_dict，并在循环中遍历 kq 的值，并将它们添加到 $kq_dict 中。在添加时，我们将值为 'null' 的元素转换为 null，并使用循环变量 $index 作为字典的键。最后，使用 array_merge() 函数将 $kq_dict 添加到 $item 中，并删除了 $item 的 kq 键在 PHP 中，使用 foreach 循环时需要将被遍历的数组或对象赋值给一个变量，而不能直接传入引用参数。因此，将 &$item 改为 $item 即可解决参数错误的问题

分离字符 使用explode()函数将字符串分割成数组，然后再将数组转换成关联数组，最后使用json_encode()函数将关联数组转换成JSON格式。$str = '08:07 16:43'; $arr = explode(' ', $str); $data = array( array('name' => 'start', 'value' => $arr[0]), array('name' => 'end', 'value' => $arr[1]) ); $json = json_encode($data); echo $json;输出结果为：[{"name":"start","value":"08:07"},{"name":"end","value":"16:43"}]其中，$data是一个二维数组，每个元素都是一个关联数组，包含name和value两个键值对。最后将$data转换成JSON格式输出。
