我得到了这个简单的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成员类型
- 如果用户选择成员类型，php脚本将执行简单的逻辑作为EMPLOYED，它将执行并返回适当的答复（请参阅我的函数以更好地理解）
- 如果用户选择"自雇、自愿会员或OFW"，则将再次执行其指定的功能
我的问题是：
程序正在运行，没有出现错误。问题是它没有显示任何内容。好像什么都没发生一样。问题出在哪里？
顺便说一句，我8个小时前刚刚学习了PHP，现在我还处于初级阶段，正在尝试这些东西。请帮帮我，我被困了几个小时了。请温柔：）

您的$a和$b超出范围。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, $b);
}
实际上，您的代码还有更多的问题，包括混合业务和表示逻辑以及职责。。。
但是，具体地说，
首先，应该使用switch而不是if/elseif 的束
第二，
你的函数employed()不知道$a是什么。你可以把它作为一个参数来提供。
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;
......
}
}
这将如预期的那样奏效。
