now i want to store this in mysql database using angular and php

Answer 1

Although it's technically possible to store an image in a BLOB type, I totally discourage you to do it and rather use a could-based filesystem such as S3 or the local filesystem of the server. Just store on the DB the URI of the image.

Storing BLOBS in the DB will make it slower, the backups will take much longer and the queries must be optimized to avoid retrieving the BLOB. A simple SELECT * FROM users; can kill your DB if you have thousands of users.
