PHP list array and get value

Question

I have some difficulties with PHP Arrays. I'm trying to foreach some values, order them with array_multisort and foreach them again so I can create some kind of code. So what I'm doing is, I'm passing json object as:

"options": [
                    {"key": "Ships From", "value": "Russia"},
                    {"key": "Color", "value": "Green"},
                    {"key": "Size", "value": "M"},
                    {"key": "Material", "value": "Flex"}
                   
            ],

So this is received from frontend, and I'm foreaching them like so:

public function findAttribute($product_id, $values)
    {
            $array = array();
            
            foreach ($values as $key => $value) {
                $getAttr = $this->attribute($value['key']);
    
                $getAttrValue = $this->attributeValue($getAttr->id, $value['value']);
    
                $code = $getAttr['label'] . '=' . $getAttrValue['value'];
                $collection = array_push($array, array($getAttr->default_order, $code));
            }
    
            array_multisort($array, SORT_ASC);
}

As you can see I have $getAttr and $getAttrValue, that selects values from database, in order to get default_order (integer) so I can sort them with multisort. So actually this code works as expected, and when I write (after multisort) like:

foreach($array as $key => $value){
            echo $value[1] .'/';
        }

I have expected value, but when I call that function it gives me that it returns NULL, if I change echo to return, I have only first array. If I try like

foreach($array as $key => $value){
            $code = $value[1] .'/';
}
return $code;

No success as well. What should I do?

Have you look at PHP methods array_search ?

Because in each iteration you assign a new value to $code so you will only get the last $value [1] in the array (after arranged). If you want to return a string concatenating all values, you could do as this:

$code = '';
foreach($array as $key => $value){
    $code .= $value[1] .'/';
}
return $code;

$code = array();
foreach($array as $key => $value){
        $code = $value[$key] .'/';
}
return $code;

Implement your code i hope that will work.
