4 min readIn Laravel, you can limit the depth of reply comments by defining a maximum depth level in your comment model or controller. This can be achieved by adding a depth column to your comment table and setting a maximum depth value (e.g. 3 levels deep).When inserting a new reply comment, you can check the depth level of the parent comment and increment it by one. If the depth level exceeds the maximum limit, you can prevent the new comment from being added or display an error message to the user.

Alternatively, you can use the create() method of the model to save the array data directly to the database. Remember to properly validate and sanitize the array data before saving it to prevent any security vulnerabilities.
