PHP如何遍历一个post数组

问题描述

我需要遍历一个post数组并对其求和.

I need to loop through a post array and sumbit it.

#stuff 1
<input type="text" id="stuff" name="stuff[]" />
<input type="text" id="more_stuff" name="more_stuff[]" />
#stuff 2
<input type="text" id="stuff" name="stuff[]" />
<input type="text" id="more_stuff" name="more_stuff[]" />

但是我不知道从哪里开始.

But I don't know where to start.

推荐答案

这是您要执行的操作:

foreach( $_POST as $stuff ) {
    if( is_array( $stuff ) ) {
        foreach( $stuff as $thing ) {
            echo $thing;
        }
    } else {
        echo $stuff;
    }
}

这会照顾在$_POST中传递的变量和数组.

This looks after both variables and arrays passed in $_POST.
