Superglobal GET using PHP - php

Question

I am new to php and I couldn't find the answer on stack. I am experimenting and trying to figure out how I can use the superglobal GET to display an image and also change the *count depending on how the user modifies it in the URL.
I would like to change the Beach image count times.
So the URL would look something like:
website.com/table?beach_image=2&count=4
and would display the beach image #2, 4 times:
bathing suit
<?php
$beach = ['sunglasses.jpg','suncreen.jpg','bathing-suit.jpg','hat.jpg'];
$count = 1;
$beach_image = filter_input(INPUT_GET,"beach_image");
?>
for my html:
<table>
<tr>
<th>Beach Image</th>
<th>Beach</th>
</tr>
<tr>
<td>0</td>
<td>Sunglasses</td>
</tr>
<tr>
<td>1</td>
<td>Sunscreen</td>
</tr>
<tr>
<td>2</td>
<td>Bathing Suit</td>
</tr>
<tr>
<td>3</td>
<td>Hat</td>
</tr>
</table>
<div>
<img src="images/<?= $beach[$beach_image]?>">
</div>

Answer 1

You can do it like below
<?php
$beach = ['sunglasses.jpg','suncreen.jpg','bathing-suit.jpg','hat.jpg'];
$keysArr = array_fill(0,count($beach),0);//array_combine(array_keys($beach),array_fill(0,count($beach),0));
$beach_image = filter_input(INPUT_GET,"beach_image");
$count = filter_input(INPUT_GET,"count");
$keysArr[$beach_image] = $count;
?>
<table>
<tr>
<th>Beach Image</th>
<th>Beach</th>
</tr>
<tr>
<td><?php echo $keysArr[0] ;?></td>
<td>Sunglasses</td>
</tr>
<tr>
<td><?php echo $keysArr[1] ;?></td>
<td>Sunscreen</td>
</tr>
<tr>
<td><?php echo $keysArr[2] ;?></td>
<td>Bathing Suit</td>
</tr>
<tr>
<td><?php echo $keysArr[3] ;?></td>
<td>Hat</td>
</tr>
</table>
<div>
<?php for($i=1;$i=$count;$i++){?>
<img src="images/<?= $beach[$beach_image]?>">
<?php }?>
</div>
