PHP循环两个数组

Question

$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   
    ) 
) 

我需要通过$ ARR1循环，以这种方式插入

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); 

等

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);  

等上。我怎样才能做到这一点？

Answer 1

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