Question: I want to get the data from WordPress DB, pushed them into array and past the data to JS.

Got it all working except pushing the data into array in `foreach ($posts as $post)`.

Full method: 

```
        $array = array(); 
        $category_name = "locations";
        $args = array(
            'numberposts' => -1,
            'category_name' => $category_name
        );

        $posts = get_posts($args);      
        foreach ($posts as $post){
            array_push( $array, array(

                "title" => the_title($post->ID),
                "cnt" => the_content($post->ID),
                "id" => the_ID($post->ID),
                "link" => the_permalink($post->ID)

            )); 
        }

```

When I do `print_r($array)` i get a following mix:

```
Post 39http://localhost:8080/testing/post-3/Post 27http://localhost:8080/testing/post-2/Post 15http://localhost:8080/testing/post-1/Array
(
    [0] => Array
        (
            [title] => 
            [cnt] => 
            [id] => 
            [link] => 
        )

    [1] => Array
        (
            [title] => 
            [cnt] => 
            [id] => 
            [link] => 
        )

    [2] => Array
        (
            [title] => 
            [cnt] => 
            [id] => 
            [link] => 
        )

)

```

**What is going on? Why is the data not placed correctly into the array?**
Any suggestions much appreciated.

Answer: 
If in doubt, using a List is likely to be a better choice even if you know the length.

Using an array can be better for performance, but you need to be an expert to know when this is a good idea, and when it just makes your solution more complicated.

BTW: There is no such thing as `dynamic arrays` in Java.
You are doing it right.

List is an Interface and ArrayList is the implementation. If you do not care much for OO mambo-jumbo, here is how you can understand it.

List is the way you want to deal with the "system". You don't care much for anything else.

But the "system" has the freedom to implement it in several ways! ArrayList, LinkedList, Vector etc.

Once you understand this separation, then try to glean the differences and nuances between these implementations.
