Module development and code questions

Drupal 9

I'm creating a drupal module that calls a php file to render an image.

current code:

$callphp .= '<img src="/path/path/path/test.php?a=0065&b=15>';

$output .= t($callphp);

return $output

the file is never called so I checked the elements in the browser and spaces and quotes are being added to look like:

<img src=" path path path test.php?a="0065&b=15">

The website encountered an unexpected error. Please try again later.

Drupal\Component\Plugin\Exception\PluginNotFoundException: The "post_type" entity type does not exist. in Drupal\Core\Entity\EntityTypeManager->getDefinition() (line 143 of core/lib/Drupal/Core/Entity/EntityTypeManager.php).

and the second
