【4个数组同时写到数据库怎么写？】

$_POST['a']       值为1,2,3,4,5
$_POST['b']       值为a,b,c,d,e
$_POST['c']       值为男,女,女,男,男
$_POST['d']       值为25,26,27,26,26


这四个数组同时是从里接收过来的。现在我要把它们都写入到数据库里，循环应该怎么写？

最后写到数据库的格式应该是
               编号 姓名   性别 年龄
第一条：1       a         男     25
第二条：2       b         女     26
第三条：3       c         女     27
第四条：4       d         男     26
第五条：5       e         男     26

$_POST['a'] = array(1,2,3,4,5);$_POST['b'] = array('a','b','c','d','e');$_POST['c'] = array('男','女','女','男','男');$_POST['d'] = array(25,26,27,26,26);foreach($_POST['a'] as $i=>$v) {  $sql = "inser into tbl_name values('$v', '{$_POST['b'][$i]}', '{$_POST['c'][$i]}', '{$_POST['d'][$i]}')";  echo $sql, PHP_EOL;}

inser into tbl_name values('1', 'a', '男', '25')
inser into tbl_name values('2', 'b', '女', '26')
inser into tbl_name values('3', 'c', '女', '27')
inser into tbl_name values('4', 'd', '男', '26')
inser into tbl_name values('5', 'e', '男', '26')

$_POST['a'] = '1,2,3,4,5';$_POST['b'] = "a,b,c,d,e";$_POST['c'] = "男,女,女,男,男";$_POST['d'] = "25,26,27,26,26";$a = explode(',', $_POST['a']);$b = explode(',', $_POST['b']);$c = explode(',', $_POST['c']);$d = explode(',', $_POST['d']);foreach($a as $key=>$value){    $sql = "inser into tbl_name values('$value', '{$b[$key]}', '{$c[$key]}', '{$d[$key]}');";    //mysql_query($sql);    echo $sql, PHP_EOL;
