How to make comparison on two parameters?

Question

PHP

Good day, please tell me how to compare 2 parameters with a POST request from the database? For example, if the First Name, Last Name and Date of Birth match, then do not write down the data, and if not, then write it down. Here's how I compare the data from the POST request with the data from the database. Tell me please!

Answer 1

in the end, while waiting for an answer, I solved this problem myself, I don’t know if it will come in handy for someone:

if( R::exec('SELECT * FROM `dlepisode1` WHERE `nickname` = ? AND `games` = ?', array($data['nickname'], $data['gamesname'])) > 0)

Answer 2

Create a composite key on the fields Last Name, First Name, Date of Birth, and use INSERT ... ON DUPLICATE KEY UPDATE:
