循环通过发布的值来查看是否有相等的“否”

Question

如何循环浏览帖子并查找是否有任何答案为“否”？

到目前为止，这是我的代码：

if($_POST["minRequirementsForm"]) {
    foreach($_POST as $key => $value) { 
        $_SESSION['minrequirements'][$key] = $value;
    }
}

提前致谢。

Answer 1

您可以使用in_array（）或array_search（）并保存循环：

if (in_array('no', $_POST)) echo 'they said no'.
if (($key = array_search('no', $_POST)) !== false) echo "$key was answered with no";

Answer 2

if($_POST["minRequirementsForm"]) {
    foreach($_POST as $key => $value) {
        if ('no' == $value) {
            // do something
        } 
        $_SESSION['minrequirements'][$key] = $value;
    }
}

Answer 3

$NoAsnwers = false;
if($_POST["minRequirementsForm"]) {
    foreach($_POST as $key => $value) { 
        if ($value == 'No') $NoAsnwers = true;
    }
}

也许是这样？
