How to change which variable is used, depending on another value - php

Question

I'm trying to make a fun side project and have come to a stop on a small problem. I am trying to have the echo command placed inside of the while and mysqli_fetch_assoc command as the data changes everytime the page refreshes, from the select from table random function.
I select random items like this:
$survivor_set = random_survivor();
$item_set = random_item();
$firstaidkitaddon_set = random_firstaidkitaddon();
$flashlightaddon_set = random_flashlightaddon();
$keyaddon_set = random_keyaddon();
$mapaddon_set = random_mapaddon();
$toolboxaddon_set = random_toolboxaddon();
$survivoroffering_set = random_survivoroffering();
The problem line of code looks like this:
<?php while($toolboxaddon = mysqli_fetch_assoc($toolboxaddon_set)) { ?>
However I need the words after $ to be changed so was looking for something like this to work:
<?php while($ echo h($item['item']);addon = mysqli_fetch_assoc($ echo h($item['type']);addon_set)) { ?>
This is probably explained poorly, I would appreciate if anyone could lend some time to help me where I can show in more details what exactly I am trying to accomplish.
The code shows the random item that was selected from the table.
<?php while($item = mysqli_fetch_assoc($item_set)) { ?>
<?php echo h($item['name']);?> E.g. Engineers Toolbox
<?php echo h($item['rarity']);?> E.g. veryrare
<?php echo h($item['type']);?> E.g. toolbox
<?php echo h($item['media']);?> E.g. engineerstoolbox.png
<?php } ?>
I am then trying to find a way to put the echo h($item['type']) into the next output. so it would look like this when it is a toolbox.
<?php while($toolbox = mysqli_fetch_assoc($toolbox_set)) { ?>
But then could change due to it being a different item type that was pulled:
<?php while($flashlight = mysqli_fetch_assoc($flashlight_set)) { ?>

You should store all your different add-on results in an associative array where the keys match the possible "type" values from your main item query. This allows you to select an item from the array using a string to reference its key - and you can take that string value from your $item['type'] variable.
e.g.
$survivor_set = random_survivor();
$item_set = random_item();
$addons = array(
"firstaid" => random_firstaidkitaddon(),
"flashlight" => = random_flashlightaddon(),
"key" = random_keyaddon(),
"map" = random_mapaddon(),
"toolbox" => random_toolboxaddon()
);
$survivoroffering_set = random_survivoroffering();
Then later on you can select the right set of results from the associative array by selecting the index which matches $item['type']:
<div class="itemaddonscontainer">
<div class="<?php echo h($item['type']);?>">
<?php while($addon = mysqli_fetch_assoc($addons[$item['type']])) { ?>
<img class="<?php echo h($addon['rarity']);?> survivor-item" src="imgs/survivor/itemaddon/<?php echo h($addon['media']);?>"/>
<?php } ?>
</div>
</div>
N.B. mysqli_free_result probably isn't necessary here.
