为什么即使在字符串上使用stripslashes和strip_tags后仍然会出现额外的斜杠？

I've one string in a variable titled $message.

After echo stripslashes(strip_tags($message)); I got following output.

Michael Clarke commented on Darren Lehmann's status update "ߘðߘİߘ0ߘʢغ️"

Now after executing the statement echo json_encode($message); I got following output :

Michael Clarke commented on Darren Lehmann's status update \"ߘðߘİߘ0ߘʢغ️\"

My concern is I won't want the extra backslash and also the garbage data appeared in the final output. How to remove them?

Please guide me where I'm making a mistake in my code?

Thanks in advance.
