 $arr1 = array(
    1 => array(
        30 => 100
        31 => 800
    ),
    2 => array(
        30 => 200
        31 => 900
    ),
    3 => array(
        30 => 300
        31 => 100
    ),
    4 => array(
        30 => 400
        31 => 110
    ),
    5 => array(
        30 => 500
        31 => 120
    ),
    6 => array(
        30 => 600
        31 => 130
    ),
    7 => array(
        30 => 260
        31 => 140
    )
);
 

 $arr2 = array(
    0 => array(
        id => 30  
    ),
    1 => array(
        id => 31          
    )
)
 

Мне нужно перебрать $arr1 и вставить таким образом

 INSERT INTO tablename (option_value_id,duration_id,price) VALUES ('30','1',100);
INSERT INTO tablename (option_value_id,duration_id,price) VALUES ('30','2',200);
INSERT INTO tablename (option_value_id,duration_id,price) VALUES ('30','3',300);
INSERT INTO tablename (option_value_id,duration_id,price) VALUES ('30','4',300);
INSERT INTO tablename (option_value_id,duration_id,price) VALUES ('30','5',500);
 

и так далее

 INSERT INTO tablename (option_value_id,duration_id,price) VALUES ('31','1',900);
INSERT INTO tablename (option_value_id,duration_id,price) VALUES ('31','2',900);
INSERT INTO tablename (option_value_id,duration_id,price) VALUES ('31','3',100);
INSERT INTO tablename (option_value_id,duration_id,price) VALUES ('31','4',110);
INSERT INTO tablename (option_value_id,duration_id,price) VALUES ('31','5',120);    
 

и так далее. Как я могу это сделать?

   foreach ($arr2 as $id)
  {
    foreach ($arr1 as $i => $v)
    {
        query("insert into tablename (option_value_id,duration_id,price)"
            . " values ('$id','$i',$v)");
    }
  }
