Single Quotes for JavaScript String: The [removed].href expects a string for the URL. In JavaScript, strings are typically enclosed in single (') or double (") quotes. Here, we use single quotes for the URL string.
PHP Echo:<?php echo ... ?> is used to output the result of the PHP expression directly into the HTML.
base_url('read-blog/'): This PHP function (common in frameworks like CodeIgniter) generates the base URL of your application followed by the segment 'read-blog/'. The trailing slash / is important to create a clean URL structure before the ID.
Concatenation (.): In PHP, the dot (.) operator is used to concatenate (join) strings. So, base_url('read-blog/') is joined with the value of the $id variable.
