Array to string conversion problem in php

Question

foreach($data['sku'] as $key=>$val) {
    $attribute = new ProductsAttributes;
    $attribute->product_id = $id;
    $attribute->sku = $val;
    $attribute->size = $data['size'][$key];
    $attribute->price = $data['price'][$key];
    $attribute->stock = $data['stock'][$key];
    $attribute->save();
}

I don't understand this code because of $data['size'][$key]. Why do I have to use $key instead of $val ? If I use $val, it throws an array to string conversion error

You need to show what the values of $data['sku'] is, try with dd($data['sku']); — mrhn

You have to use like this

foreach($data as $key=>$val) {
    $attribute = new ProductsAttributes;
    $attribute->product_id = $id;
    $attribute->sku = $val['sku'];
    $attribute->size = $val['size'];
    $attribute->price = $val['price'];
    $attribute->stock = $val['stock'];
    $attribute->save();
}
