foreach($_POST['LoginForm'] as $name =>$value)

红色部分啥意思？

回复讨论(解决方案)

=> 表示数组成员
左边是下标或关联键，右边是值

你就理解是一种格式就好了，就像新建一个数组$arr=array($key=>$value);左边的代表下标、关联键值，右边是值

foreach ($_POST['LoginForm'] as $name=>$value)

这也是我刚刚才了解的不知道说的对不对 ..
将 $name=>$value（键值对）遍历后放入 $_POST['LoginForm']数组

但是loginForm表示什么

红色部分，表示“对应的”意思吧，也就是数组里面 key 对应的成员 val 值，两者对应。

key表示位置 val表示值 =>表示位置对应的值。
