表单操作目标 PHP 文件被下载而不是被解析

Question

表单

操作中引用的PHP文件被下载而不是解析！下面是激活事件的代码：

<form method="post" action="./php/signup.php">

这是 PHP 文件：

$username = $_POST["username"];
$first = $_POST["first"];
$last = $_POST["last"];
$passworda = $_POST["passworda"];
$passwordb = $_POST["passwordb"];
$emaila = $_POST["emaila"];
$emailb = $_POST["emailb"];
if ($passworda != $passwordb) {
        echo "Passwords do not match!";
} else {
        echo "Password Check Complete!";
}
if ($emaila != $emailb) {
        echo "E-Mails do not match";
} else {
        echo "E-Mail Check Complete!";
}

可能出现什么问题？
