I have product options that came from database and I want to merge all the values by same product_id .
I'm using a foreachloop.
stdClass Object(
[id] => 22
[product_id] => 48
[values] => Array (
[0] => stdClass Object (
[id] => 81
[option_id] => 22
[name] => Black
[value] => black
)
)
),
stdClass Object(
[id] => 10
[product_id] => 50
[values] => Array (
[0] => stdClass Object (
[id] => 33
[option_id] => 10
[name] => L
[value] => l
),
[1] => stdClass Object (
[id] => 34
[option_id] => 10
[name] => M
[value] => m
)
)
),
stdClass Object(
[id] => 24
[product_id] => 48
[values] => Array (
[0] => stdClass Object (
[id] => 98
[option_id] => 11

You can try something like this :
1/ Your data
$array = /* array with all your product obj */;
// Create your new result array
$result = array();
2/ The foreach loop
// Loop throught all your object
foreach ($array as $obj) {
// Your current product id
$current_product_id = $obj->product_id;
// The values of this product
$current_product_values = $obj->values;
// Loop through all the value of the product
foreach ($current_product_values as $value) {
// Add those value to your result array for the current product id
$result[$current_product_id][] = $value;
}
}
