Using jQuery you can do like below:

$(document).ready(function() {
  $('img').attr('src', $('img').parent('a').attr('href'));
});

Working snippet:-

 $(document).ready(function() { $('img').attr('src', $('img').parent('a').attr('href')); });

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <a href="data/abc.png"> <img src="test.png"> </a>

Note:- if your document have multiple <a> with <img> in it, above code will change src of all.So be careful.

In PHP (update your code like below):

<a href="<?php php code to get href value ?>">
  <img src="<? write the same php code to get href value ?>">
</a>
