Question

我有这个简单的PHP脚本。它的作用是：

用户将输入其工资。
用户将从下拉列表中选择其会员类型。
php脚本将执行简单的逻辑作为雇员，它将执行并返回适当的答复 （请参阅我的功能以便更好地理解）
如果用户选择“自雇，自愿会员或OFW”，则为将再次执行其指定的功能

我的问题是什么：

程序正在运行且没有错误。问题是它没有显示任何东西。好像什么也没发生。什么似乎是问题？

顺便说一下，我刚刚在8小时前学习过PHP，我还在初学阶段试图尝试这些东西。请帮我。在这上面被困了几个小时。请温柔：）

<form method="POST">

Answer 1

您的$a和$b超出了范围。您需要将它们作为参数传递给函数。

/* SNIP */
function employed($a, $b) { //Note that the function now accepts two parameters. These will be available in the function.

/* SNIP */
function sevmofw($a, $b) { //Same idea.

/* SNIP */
if ($_POST['membershiptype'] == 'employed') {
    employed($a, $b); //Pass the variables into the function from the outside.
}
elseif ($_POST['membershiptype'] == 'SE') {
    sevmofw($a, $b);
}
elseif ($_POST['membershiptype'] == 'VM') {
    sevmofw($a, $b);
}
elseif ($_POST['membershiptype'] == 'OFW') {
    sevmofw($a, $b);
}

Answer 2

实际上，您的代码存在更多问题，包括混合业务和表示逻辑以及职责......

但是，具体到这个问题，

首先，应该使用switch而不是if/elseif

其次，

您的函数employed()不知道$a是什么。你会把它作为一个论据提供。

function employed($a){

   switch(true){

      case $a < 100:

        echo "Your Salary for the Period is $a. <br> You didn't reach the minimum compensation for the period. No SSS Contribution Deduction."   

      break;

      case $a < 1249.99:
         echo "Your ER is 80.7 and Your EE is 33.3 sevmofw";
      break;

      ......
   }
}

这将按预期工作。

PHP函数不执行简单的逻辑任务
