如何正确使用array_push作为另一个数组的键和值

问题描述：

So I am using this code to push new user IDs into an array but I get

Warning: array_push() expects at least 2 parameters, one given

$post_likes = array(
"Some key" => array(
             'date' => date("d/m/Y"), 
             'IP' => get_client_ip())
             ); 
$new_likes = array(
             'date' => date("d/m/Y"), 
             'IP' => get_client_ip());
array_push($post_likes[$current_user->ID] = $new_likes);

The code works. It pushes new key with array value into the previous array. But still I get that warning. What am I missing?

所以我使用这段代码将新的用户ID推送到一个数组中，但是我得到了 p> \ n

警告：array_push（）需要至少2个参数，一个给定 p> blockquote>

  $ post_likes = array（
“ 一些关键的“=＆gt;数组（
'日期'=＆gt;日期（”d / m / Y“），
'IP'=＆gt; get_client_ip（））
）;  
 $ new_likes = array（
'date'=＆gt; date（“d / m / Y”），
'IP'=＆gt; get_client_ip（））; 
array_push（$ post_likes [$ current_user-＆gt;  ID] = $ new_likes）; 
  code>  pre> 
 
 代码有效。 它将具有数组值的新键推送到前一个数组中。 但我还是得到了警告。 我错过了什么？ p> 
  div>

答

Instead of using array_push() you can directly do like this-

$post_likes[$current_user->ID] = $new_likes;

A sample hardcoded example:- https://eval.in/1000261

答

Set your new variable $new_likes as like this:

array_push($post_likes[$current_user->ID] = $new_likes,$new_likes);   //expects at least 2 parameters

Updated:

I am proffering and suggesting to use @Magnus Eriksson's answer though you have accepted my answer.

So, just use as like below:

$post_likes[$current_user->ID] = $new_likes;
