The official Wordpress documentation can be found here.

How can I get post data from a WP_Query array in a multidimensional array?

How can I get $value array values from object(WP_Query)?

post_content, ID, pagename, category etc.

Here is my code:


    global $post;
    
    $args = array(
        'post_type' => 'history',
        'order'     => 'ASC'
    );
    
    $master = [];
        
    $post_query = new WP_Query($args);
    
    if ($post_query->have_posts() ) {
                
        while ($post_query->have_posts()) {
                
            $post_query->the_post();
            
            /* Get Post Date */
            $year = get_the_date( 'Y' );
            $mon = get_the_date( 'M' );
                
            $master[$year][$mon][] = $post_query;
            
        }
        
        foreach ($master as $masterkey => $mastervalue) {
            echo "<p>";

            echo "masterkey: ".  $masterkey . "<br>";

            foreach($mastervalue as $key => $value) {
                echo "key: " . $key . "<br>";
                echo "value: " . $value . "<br>";
                                        
            }
            
            echo "</p>";
        }
        
    }

wp_reset_postdata();

var_dump for $value array:

    Try to ensure $master is a multi-dimensional array before assigning values like $master[$year][$mon][] = $post_query;

    while ($post_query->have_posts()) {
                
    $post_query->the_post();
            
    /* Get Post Date */
    $year = get_the_date( 'Y' );
    $mon = get_the_date( 'M' );
    
    if (!is_array($master[$year]) {
        $master[$year] = [];
    }
    if (!is_array($master[$year][$mon]) {
        $master[$year][$mon] = [];
    }
    $master[$year][$mon][] = $post_query;
            
}

    If this question is related to this question of yours, and you need the title of each post in this format Year > Months > Title of each post, then you could use the following code:

    $posts = get_posts(array(
  'post_type' => 'history',
  'posts_per_page' => -1,
  'orderby'   => 'date'
));

$master = [];

foreach ($posts as $post) {
  setup_postdata($post);

  $time = strtotime($post->post_date);
  $year = date('Y', $time);
  $mon = date('F', $time);

  $master[$year][$mon][] = $post->post_title;
}

wp_reset_postdata();


foreach ((array)$master as $yearly => $yvalue) {
  echo $yearly . ": <br>";
  echo "<ul>";
  foreach ($yvalue as $monthly => $mvalue) {
    echo "<li>" . $monthly . ": </li>";
    echo "<ul>";
    foreach ($mvalue as $post_title_k => $post_title_v) {
      echo "<li>" . $post_title_v . "</li>";
    }
    echo "</ul>";
  }
  echo "</ul>";
}

    Notice that i used post_title from the post object. Which will return the following output:

    2021:
  January:
    1.Post Title
    2.Post Title
  March:
    3.Post Title

2020:
  May:
    4.Post Title

    When you use get_posts it will return post objects. Each object includes the followings:

    WP_Post Object
(
    [ID] =>
    [post_author] =>
    [post_date] => 
    [post_date_gmt] => 
    [post_content] => 
    [post_title] => 
    [post_excerpt] => 
    [post_status] =>
    [comment_status] =>
    [ping_status] => 
    [post_password] => 
    [post_name] =>
    [to_ping] => 
    [pinged] => 
    [post_modified] => 
    [post_modified_gmt] =>
    [post_content_filtered] => 
    [post_parent] => 
    [guid] => 
    [menu_order] =>
    [post_type] =>
    [post_mime_type] => 
    [comment_count] =>
    [filter] =>
)

    In the code above i accessed $post->post_title in this line $master[$year][$mon][] = $post->post_title.
