我可以在多维数组中存储数组吗？（PHP）

发布于 2024-10-31 10:00:27 字数 89 浏览 1 评论 0原文

是否可以将数组放入多维数组中？我有一个用户设置列表，我想在 JSON 数组中返回它，并且还有另一个数组存储在该 JSON 数组中...如果不可能，最好的方法是什么？

多维已经是数组内的数组。所以没有什么可以阻止你在那里放置另一个数组。有点像梦中之梦：P

如果您想赋予数组含义，只需使用关联数组

array(
   'SETTINGS' => array(
      'arr1' => array( 0, 1),
      'arr2' => array( 0, 1)  
   ),
   'DATA' => array(
      'arr1' => array( 0, 1),
      'arr2' => array( 0, 1)  
    )
)

要回答您的评论，$output_files[$file_id]['shared_with'] = $shared_info ; 翻译为（您的评论有一个额外的 ] 我删除了）

$shared_info = array(1, 2, 3);
$file_id     = 3;
$output_files = array(
  '3' => array(
     'shared_with' => array() //this is where $shared_info will get assigned
   )
);
//you don't actually have to declare it an empty array. I just did it to demonstrate.
$output_files[$file_id]['shared_with'] = $shared_info; // now that empty array is replaced.

A multi dimension is already an array inside an array. So there's nothing stopping you from putting another array in there. Sort of like dreams within dreams :P

Just use associative arrays if you want to give your array meaning

array(
   'SETTINGS' => array(
      'arr1' => array( 0, 1),
      'arr2' => array( 0, 1)  
   ),
   'DATA' => array(
      'arr1' => array( 0, 1),
      'arr2' => array( 0, 1)  
    )
)

EDIT

To answer your comment, $output_files[$file_id]['shared_with'] = $shared_info; translates to (your comment had an extra ] which I removed)

$shared_info = array(1, 2, 3);
$file_id     = 3;
$output_files = array(
  '3' => array(
     'shared_with' => array() //this is where $shared_info will get assigned
   )
);
//you don't actually have to declare it an empty array. I just did it to demonstrate.
$output_files[$file_id]['shared_with'] = $shared_info; // now that empty array is replaced.
