strict comparison should be added to check the compare in wp-include comment.php

[deepakrohilla]

A strict comparison should be added in the pingback function within wp-includes/comment.php to ensure accurate ID matching. The url_to_postid function is used to fetch the ID and returns an integer value, and $post->ID also returns an integer. To improve precision, a strict comparison should be used when comparing these integer values.
and also in multiple palaces in comment.php strict comparison should be added.
