One header but with different banners for each page (php if)

Question

I build my website for fun and want to put different banner on each page, in my header i have random banners who appear with this code,

<div style=' height:145px; background-image:url(images/banners/banner<?php 
echo rand(1,3); ?>.jpg); background-position:center center; border-
radius:4px;'></div>

So there is 3 banners and each time i refresh random one appear, but i want to have another 3 banners for my other page but with the same include"inc/header.php", maybe 'if' statement could work but i really don't know how to do it. Sorry for my English i'm french.

Answer 1

Assuming the three banners are in the same folder, the following would be a simple solution:

Place the banner code in a separate file:

banner.php

    <div style=' height:145px; background-image:url(images/banners/banner<?php 
echo rand($start,$end); ?>.jpg); background-position:center center; border-
radius:4px;'></div>

Then you can call it from your page:

$start = 4;  //First banner number
$end = 6;    //Last banner number
include('inc/banner.php');

This is not the most elegant solution, but it's a simple nice simple one for a novice programmer that introduces some concepts.

Answer 2

use if
example
if ($id == 1){
   <div style=' height:145px; background-image:url(images/banners/banner<?
      php 
          echo rand(1,3); ?>.jpg); background-position:center center; 
    border-
               radius:4px;'></div>
      }
             if ($id == 2){
         <div style=' height:145px; background-
      image:url(images/banners/banner<?php 
     echo rand(1,3); ?>.jpg); background-position:center center; border-
   radius:4px;'></div>
      }
    if ($id == 3){
         echo "no banner";
              }

Answer 3

I found how to do it myself:

<?php if ($title == "page1"): ?>
<div style=' height:145px; background-image:url(images/banners/banner<?
php echo rand(1,6); ?>.jpg); background-position:center center; border-
radius:4px;'></div>

<?php elseif ($title == "page2"): ?>
<div style=' height:145px; background-image:url(images/banners/banner<?php 
echo rand(7,9); ?>.jpg); background-position:center center; border-
radius:4px;'></div>

<?php endif; ?>

I just need to create new "elseif" for every page and assign new banners with the same header.php all over my website.
