5个数组同时写到数据库怎么写?

Jun 23, 2016 pm 01:54 PM
database array

$_POST['a']       值为1,2,3,4,5
$_POST['b']       值为a,b,c,d,e
$_POST['c']       值为6,7,8,9,0
$_POST['d']       值为h,i,j,k,l
$_POST['e']       值为o,p,q,r,s

这五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?   foreach貌似只能针对一个数组。


最后写到数据库的格式应该是
第一条:1 a 6 h i
第二条:2 b 7 i p
第三条:3 c 8 j q
第四条:4 d 9 k r
第五条:5 e 0 l s

foreach($_POST['a'] as $i=>$a) {  $b = $_POST['b'];  $d = $_POST['c'];  $d = $_POST['d'];  $e = $_POST['e'];  //与 $a,$b,$c,$d,$e 相关的操作}
Copy after login
Copy after login

也可以
foreach(array_map(null, $_POST['a'], $_POST['b'], $_POST['c'], $_POST['d'], $_POST['e']) as $r) {  //对 $r 的相关操作}
Copy after login
Copy after login

foreach($_POST['a'] as $i=>$a) {  $b = $_POST['b'];  $d = $_POST['c'];  $d = $_POST['d'];  $e = $_POST['e'];  //与 $a,$b,$c,$d,$e 相关的操作}
Copy after login
Copy after login

也可以
foreach(array_map(null, $_POST['a'], $_POST['b'], $_POST['c'], $_POST['d'], $_POST['e']) as $r) {  //对 $r 的相关操作}
Copy after login
Copy after login




我每一列在数据库中都对应一列,这样子貌似不好一条一条的写入了

你自己看看循环中得到的都是什么
