在PHP中使用字符串键创建多维数组

Question

This is kinda dumb question but after all these tries i get confused when i go too far...
I want a data like: Name Price Owner in different arrays as categories.
Like ie. i would like to access it via $product['category']['name']['name'] or $product['category']['name']['price'].
However i would need to check in which categories there is key ['name'] as well.
Any examples would be nice to learn from ;)

Answer 1

You can loop array:

foreach($product['category'] as $cat) {
    if (isset($cat['name']) { //this is true if 'name' have value different than null
        continue; //cat have name
    }
}
