$_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
回复讨论(解决方案) $_post['a'] = array(1,2,3,4,5);$_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;}
