PHP – Add multiple items by index to multidimensional array

December 8, 2021

I have this array called $all_cats which outputs the following

Array(
    [0] => WP_Term Object(
        [term_id] => 386
        [name] => Ales
        [slug] => ales
        [term_group] => 0
        [term_taxonomy_id] => 386
        [taxonomy] => product_cat
        [description] => 
        [parent] => 384
        [count] => 10
        [filter] => raw
    )
    [1] => WP_Term Object(
        [term_id] => 385
        [name] => Beers
        [slug] => beers
        [term_group] => 0
        [term_taxonomy_id] => 385
        [taxonomy] => product_cat
        [description] => 
        [parent] => 384
        [count] => 10
        [filter] => raw
     )
)

I’m trying to add the "term_id" and "name" to an indexed multidimensional array so i can output the following –

Example A

Array
(
    [0] => Array
        (
            [parent_cats] => Array
                (
                    [id] => 385,
                    [name] => "Beers"
                )
        )
    [1] => Array
        (
            [parent_cats] => Array
                (
                    [id] => 386,
                    [name] => "Ales"
                )

        )
)

I’ve tried the following but cant seem to add each item to the same key. How can i add each term_id & name so it outputs like example A?

$full_cats = array();

foreach ($all_cats as $cat_term) {

    $parent_termID = $cat_term->term_id;
    $parent_title = $cat_term->name;

    // this doesnt work
    $full_cats[]['parent_cats']['id'] = $parent_termID;
    $full_cats[]['parent_cats']['name'] = $parent_title;

    // this doesnt work
    array_push($full_cats[]['parent_cats']['id'],$parent_termID);
    array_push($full_cats[]['parent_cats']['name'],$parent_title);

}

>Solution :

$full_cats = array();

foreach ($all_cats as $cat_term) {
    $parent_termID = $cat_term->term_id;
    $parent_title = $cat_term->name;

    // this doesnt work
    $full_cats[]=array(
                      "parent_cats"=>array(
                                       "id"   => $parent_termID,
                                       "name" => $parent_title
                      )
                  );
}

The above code should work
