A simple way to write large elseif statements in PHP

Question

I'm getting post values from an emailer form and I set all the option values to numbers and I'm trying to convert them to their actual strings to send in an email. I need to make this code easier to use.

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

Maybe I could set the value='' to the actual values and skip this part all together.

Answer 1

Why not make an associative array?

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

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

Answer 2

One way to rewrite is to use the switch statement in PHP. You can read more about it here .

Answer 3

Use a switch statement, or map the potential outcomes to their respective values:

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

Or

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

Answer 4

Try this

<?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 = "";
}
?>
