我有两个具有关系的表
+----------------------+ +-----------------+
| Shape | | Point_Values |
+----------------------+ +-----------------+
| shape_id (KEY) | | id (KEY) |
| shape_name (VARCHAR) | | point_x (INT) |
+----------------------+ | point_y (INT) |
| shape_id (INT) |
+-----------------+
如何在同一请求中同时获取形状和点，这意味着当形状完成时，会出现一个点数组和形状名称/id 。我必须在表中插入，但 shape_id 都匹配。

最佳答案
考虑到该数组，这段代码应该可以很好地工作。它执行一次初始插入以从表格形状中获取 id，并且所有点都会批量插入。
function insertShape($s){
mysql_query('INSERT INTO shape (name) VALUES ("'.$s['name'].'");');
$id=mysql_insert_id();
$i=0;
for(;;){
if(!isset($s['points']['x'][$i], $s['points']['y'][$i]))break;
$inserts[]='('.$id.','.$s['points']['x'][$i].','.$s['points']['y'][$i].')';
$i++;
}
mysql_query('INSERT INTO point_values (shape_id,x,y) VALUES '.implode(',',$inserts));
}
如果您的情况不需要对按键进行严格的测试，我可能会将其设为 foreach。
