Question

I’m having some difficulty writing this code in php. I want to create a random image not for background which I learn from my previous thread but I want to learn how to create a random image. Here is what I got so far I only did the array and the html but my php code is incomplete:

//Random Image PHP
  $images = array(array("image 1" => "caption 1"),
                  array("image 2" => "caption 2"),
                  array("image 3" => "caption 3");

//HTML
<div class="image-with-caption">
<img src="image 1/<?php echo $file; ?>.jpg" /> 
<p id="caption"><?php echo $caption; ?></p> 
</div>

I appreciate any explanation & examples.

<?php
  //Random Image PHP
  $images = array(array("image_1","caption 1"),
                  array("image_2","caption 2"),
                  array("image_3","caption 3"));
  $r = mt_rand(0,count($images)-1);
?>
//HTML
<div class="image-with-caption">
<img src="images/<?php echo $images[$r][0]; ?>.jpg" /> 
<p id="caption"><?php echo $images[$r][1]; ?></p> 
</div>
