How to replace links in Joomla module using php from external file?

Question

PHP

In the widget that displays a feed of the last 6 posts on the Instagram website, it is necessary (as I try) to insert links to these posts using the php code, through the src= and href= attributes, as shown in the screenshot. Since this widget code is built into a dozen sites, when adding new posts to Instagram, changing their url "handles" on each site is quite hemorrhoids) so I want to implement their substitution from ONE .txt or .xls file.

As an option, I tried the above combination with substitution by specifying php variables directly in the code, but it didn’t work out .. plz tell me how it is possible to implement this task?

Answer 1

Tried creating an external .php file with an ID for these six insta posts

<?php
return [
    'id1' => 'sgsg4t3451',
    'id2' => '345341vfdA',
    'id3' => 'bfgw12aAvd',
    'id4' => 'ByLrLumiMVu',
    'id5' => 'ByJFfZ4Hrlp',
    'id6' => 'ByGXC_2HshD',
];
?>

with a link to these IDs from the Joomla HTML module:
but in this case, the server still does not process the php request url giving errors:
this is how the url looks like this is what
the console outputs
