Question

Hello guys I am using this script for my pagination:

<?php
if(isset($_GET['page']) && $_GET['page'] != '') {
   $pageno = $_GET['page']; /* Sanitize Here */
} else {
   /* You can redirect user to home page */
}
?>
<?php
if(isset($pageno)) {
  if($pageno == '1') {
     ?>
<div class="container">
  <div class="examples">
    <div class="row">
      <div class="span3">

Can you see the line

elseif($pageno == '2') {

It means that page .php?page=2 will display the content below

I want to make it so every page that is higher than the number 2 will display the same page.

I’ve tried these options:

elseif($pageno == '>=2') {

elseif($pageno == '>2') {

And nothing of them works, not even an error.
I doubt you can do something this way with that script but, is there any other way to do so that works?

Thanks.

Answer 1

if ((int)$pageno >= 2) 

… should do the trick.

It actually may be written without casting to integer (or using intval function), because PHP is weakly-typed language. But I’d prefer that form to show my intention in the code more clearly. In fact, I’d change this line…

$pageno = $_GET['page'];

… to this:

$pageno = (int)$_GET['page'];

… and proceed with direct number comparisons (like $pageno === 1)
