Store array keys in variable with foreach loop PHP - php

Question

When saving in an array the prices and ids of a product, with this code...
foreach($resource->group->tabs as $tab) {
foreach($tab->articles as $article)
{
$prices_and_ids[] = array(
$article->article_erp_id => array(
'price_pvp' => $article->price_pvp,
'price_promotion' => $article->price_promotion,
)
);
}
}
The result of $prices_and_ids with this code is an object with the keys numbered:
array:10 [▼
0 => array:1 [▼
3140 => array:2 [▼
"price_pvp" => 6.5
"price_promotion" => 5.53
]
]
1 => array:1 [▼
3141 => array:2 [▼
"price_pvp" => 7.5
"price_promotion" => 6.37
]
]
2 ... ... ...
The result I want is that the article ids are the keys of the array.
I want this:
array:10 [▼
3140 => array:1 [▼
"price_pvp" => 6.5
"price_promotion" => 5.53
]
3141 => array:1 [▼
"price_pvp" => 7.5
"price_promotion" => 6.37
] ... ... ...

Answer 1

the problem with your code is your adding it in another array do this
$prices_and_ids[$article->article_erp_id]
instead of
$prices_and_ids[]
foreach($resource->group->tabs as $tab) {
foreach($tab->articles as $article)
{
$prices_and_ids[$article->article_erp_id] = array(
$article->article_erp_id => array(
'price_pvp' => $article->price_pvp,
'price_promotion' => $article->price_promotion,
)
);
}
}

Answer 2

Instead of $prices_and_ids[] you should use $prices_and_ids[$article->article_erp_id]
foreach($resource->group->tabs as $tab) {
foreach($tab->articles as $article)
{
$prices_and_ids[$article->article_erp_id] array(
'price_pvp' => $article->price_pvp,
'price_promotion' => $article->price_promotion,
);
}
}

Answer 3

Change your foreach body as following code
$prices_and_ids[$article->article_erp_id] = array(
'price_pvp' => $article->price_pvp,
'price_promotion' => $article->price_promotion,
);
