Question

Here’s my php code

<?php
$pageOK = array('page0' => 'page0.php',
                  'page1' => 'content1.php',
                  'page2' => 'anotherContent2.php',
                  'page3' => 'anotherpagewithotherlink.php',
                  'page4' => 'blablabla.php',
                  'page5' => 'bleh.php',
                  'page6' => 'foo.php',
                  'page7' => 'bar.php');


  if ( (isset($_GET['projet'])) && (isset($pageOK[$_GET['projet']])) ) {
    include($pageOK[$_GET['projet']]);   
  } 
?>

This will make in sort that “index.php?project=page0” will load in the url with mod_rewrite enable (http://www.example.com/page0/)

Note that the url is different. My question is how I can make a Prev / Next link to go to the next or previous array and if it’s the first hide the Prev link and for the last hide the Next link.

Answer 1

foreach($pageOK as $key => $val){
    if($key == $_GET['projet']){
        $next = key($pageOK);
        break;
    }
    $prev = $key;
}

$next and $prev holds the array keys.
