There are several ways to solve the problem, follow an example:

$tags_row = 'tag1, tag2, tag3';

$tags =  explode(',', $tags_row);

foreach ($tags as $item) { 
 echo "<href='#'>{$item}</a><br>"; 
}

its logic is correct, to print PHP variables using quotation marks "" dupulas in echo should use {$variavel} for php to escape the quotation marks.
