PHP电子商务声明变量

Question

我有10个包和2个基本页面的结帐页面。我是否可以在if & elseif if语句中声明变量，以便在它们为真时回显它们？

示例：

<?php 
$package = $_POST['pack'];

if($pack == 1) {
   $value = "item-1";
   $value-2 = "gross-1";
} elseif ($pack == 2) {
   $value = "item-2";
   $value-2 = "gross-2";
} elseif($pack == 3) {
   $value = "item-3";
   $value-2 = "gross-3"; {
} elseif($pack == 4) {
   $value = "item-4";
   $value-2 = "gross-4";
} elseif($pack == 5) {
   $value = "item-5";
   $value-2 = "gross-5";
} else {
$value = 0;
$value-2 = 0;
}
<form action="PayPal">
   <input value='<?php echo $value; ?>' name="whatever">
   <input value='<?php echo $value; ?>' name="whatever-2">
</form>

所以基本上我需要变量的值与真语句一致，这样它们就可以在页面中回显以显示值。

有什么建议吗？

$package = $_POST['pack'];

if($pack == 1) {
   $value = "item-1";
   $value_2 = "gross-1";
} else if ($pack == 2) {
   $value = "item-2";
   $value_2 = "gross-2";
} else if($pack == 3) {
   $value = "item-3";
   $value_2 = "gross-3"; {
} else if($pack == 4) {
   $value = "item-4";
   $value_2 = "gross-4";
} else if($pack == 5) {
   $value = "item-5";
   $value_2 = "gross-5";
} else {
$value = 0;
$value_2 = 0;
}
<form action="PayPal">
   <input value='<?php echo $value; ?>' name="whatever">
   <input value='<?php echo $value_2; ?>' name="whatever_2">
</form>
