Question

我从电子邮件形式获得职位价值,我把所有选择价值定在数字上,而Im试图将其转换到通过电子邮件发送的实际渠道。我需要使这一守则更容易使用。

if ($subject == "1") {
$sub = "General Questions"; 
} elseif($subject == "2") {
$sub = "Membership";
} elseif($subject == "3") {
    $sub = "Club Fees";
} elseif($subject == "4") {
    $sub = "Proshop &amp; Lessons";
} elseif($subject == "5") {
    $sub = "Events"; 
} elseif($subject == "6") {
    $sub == "Leagues &amp; Programs";
} elseif($subject == "7") {
    $sub == "Resturant &amp; Bar";
};

也许我可以将<代码>价值=设定到实际价值中,并且把这一部分一并计算。

Answer 1

为什么不形成一个联系阵列?

$subs = array(
  1 =>  General Questions ,
  2 =>  Membership ,
  3 =>  Club Fees ,
  4 =>  Proshop &amp; Lessons ,
  // others.
);

$sub = isset($subs[$subject]) ? $subs[$subject] :  Default Value ;

Answer 2

改写方式之一是使用PHP中的switch说明。可在

Answer 3

使用<代码>switch说明,或将潜在结果与各自数值挂钩:

switch ( $subject ) {
  case 1:
    $sub =  foo ;
    break;
  case 2:
    $sub =  bar ;
    break;
}

或

$values = array( "Foo", "bar" );
$sub = $values[ --$subject ];

Answer 4

引言

<?php
switch ($subject)
{
case "1":
  $sub = "General Questions";
  break;
case "2":
  $sub = "Membership";
  break;
case "3":
  $sub = "Club Fees";
  break;
case "4":
  $sub = "Proshop &amp; Lessons";
  break;
case "5":
  $sub = "Events";
  break;
case "6":
  $sub = "Leagues &amp; Programs";
  break;
case "6":
  $sub = "Resturant &amp; Bar";
  break;
default:
  $sub = "";
}
?>
