PHP variables set inside an EE loop are reset to a EEish value… kinda… when the loop ends?

Example:

<?php

$aaa = 1;

?>

{exp:channel:categories channel="gallery"}
 {if active}
  <?php
  
  $aaa = "{category_id}";
  echo 'AAA: '.$aaa;
  
  ?>
 {/if}
{/exp:channel:categories}

<?php

echo 'BBB: '.$aaa;

?>

...will return:

AAA: 3 
BBB: {category_id}

Why is this so?
And how are we supposed to work around it?

Is PHP running on Input or Output? I’d wager that you have it set to Input. You should try Output:
