Question

I have an array structure like so:

Array
(
    [0] => Array
        (
            [term_id] => 22
            [name] => Aaa Aa
            [slug] => aaa-aa
            [term_group] => 0
            [term_taxonomy_id] => 22
            [taxonomy] => category
            [description] => 
            [parent] => 13
            [count] => 0
            [cat_ID] => 22
            [category_count] => 0
            [category_description] => 
            [cat_name] => Aaa Aa
            [category_nicename] => aaa-aa
            [category_parent] => 13
        )

    [1] => Array
        (
            [term_id] => 11
            [name] => adasdasda
            [slug] => adasdasda
            [term_group] => 0
            [term_taxonomy_id] => 11
            [taxonomy] => category
            [description] => asdsdad
            [parent] => 1
            [count] => 0
            [cat_ID] => 11
            [category_count] => 0
            [category_description] => asdsdad
            [cat_name] => adasdasda
            [category_nicename] => adasdasda
            [category_parent] => 1
        )
)

I was wondering how to go about easily looping through the data for output…

For example, I want to display all the names, descriptions and slugs.

I can’t figure out how to display them all…

This is what I have, and it kind of works, however it’s throwing and invalid argument.

    for ($i = 0; $i <= count($data); $i++) {
    foreach($data[$i] as $key => $value){
            echo "KEY: ".$key."<br />\n VALUE: ".$value."<br />\n"; 
        }
    }

No need to use the for loop, foreach will suffice. This way you won’t have to deal with the out of boundary (index not set) warning.

$array = array(); // <- your data here
foreach ($array as $arr) {
    echo 'Name: ', $arr['name'], '<br />',
         'Description: ', $arr['description'], '<br />',
         'Slug: ', $arr['slug'], '<br />';
}
