Multiple ifs

[ItsWesYo]

I'm making a tutorial/guide for a site. There are multiple chapters (1, 2, 3, 4, etc). Instead of making multiple ifs, is there a way I can put the unfinished ones in a single line. Hard to explain :\

 

Part of guide.php

<?php
$page = $_REQUEST['i'];

if($page == "chap1"){
echo ("

<b>CHAPTER 1</b> is not available right now.

");
die();
}
?>

 

Like, I also want chap2 and chap3 to be unavailable too without making a new if($page) statement.

[darkfreaks]

<?php
$page = $_REQUEST['i'];

if($page == "chap1"|$page == "chap2"|$page == "chap3"){
echo ("

<b>Chapters 1-3</b> are not available right now.

");


die();
}
?>

You could also use a switch() statement:

<?php
if (isset($_REQUEST['i']))
    switch ($_REQUEST['i'])) {
          case 'chap1':
          case 'chap2':
          case 'chap3':
              echo '<span style="font-weight:bold;color:red">Chapters 1 - 3 are not available yet</span>';
              break;
          case 'chap4':
//
//         do other stuff
//
            break;
    }
}
?>

 

Not one line, but easier to change.

<?php
$page = $_REQUEST['i'];
$unfinished = array("chap1","chap2","chap3");
if(!in_array($page,$unfinished)){die("<b>CHAPTER 1</b> is not available right now.");}
?>

 

Is.. that what you mean? :-o

for($x=1;$x<=10;x++){
  $chapter='chapter'.$x;
  if ($page = $chapter){
  echo $chapter.' is not available';
  }
}
