                                                [slug] => finising
                                                [option] => Mata Ayam
                                            )

                                    )
                                  )
                     )
                 )
                 )
                 )

this a little my script..

<?php

 $values     = array();
 foreach ($results->products as $result) 
 {
   foreach ($result->variations as $varia) 
    {
    $values[] = "(  
                    '".$varia->id."', //ok
                    '".$result->id."', //ok
                    '".$varia->$attributes->$name."' //error
                ")
  }
}

?>

You need to either loop again over `attributes`, or access a specific element of it. — 04FS, Sep 16 '19 at 09:16
This, and you should drop the `$` before attributes, it's a field not a varible. — Entilore, Sep 16 '19 at 09:18

Attributtes its an array. You need other loop

<?php

 $values     = array();
 foreach ($results->products as $result) 
 {
   foreach ($result->variations as $varia) 
    {
        foreach($varia->attributes as $attrib)
        {
              $values[] = "(  
                    '".$varia->id."', //ok
                    '".$result->id."', //ok
                    '".$attrib->name."'
                ")

        }

  }
}

You made two mistakes: first attributes is an array, you have to loop over it.

Second, you are trying to access the attributes and name fields with an incorrect notation (the $ in front of the field name is another functionality called dynamic variables, or variable variables)

<?php

$values = [];
foreach ($results->products as $result) {
    foreach ($result->variations as $varia) {
        foreach ($varia->attributes as $attribute) {
            $values[] = "(
                    '" . $varia->id . "', //ok
                    '" . $result->id . "', //ok
                    '" . $attribute->name . "''
                )";
        }
    }
}

If you still has issues with it, maybe you can try to dump your outputs? You probably nows [print_r](https://www.php.net/manual/function.print-r.php), which can help you debugging this type of problems – Entilore Sep 16 '19 at 09:43
it works. thank you. but the output become more than one. it should just one product have 2 atribute. when use foreach more it become 2 product. – Beny Bond Banjarnahor Sep 16 '19 at 09:45
Well yeah, because each different attributes has a different name. – Entilore Sep 16 '19 at 09:57
can u share idea get 1 product and have name with two attribute in just one row in one table. because if my idea is insert product in product table and attribute in another table and when i get the data just join. – Beny Bond Banjarnahor Sep 16 '19 at 15:06
