How to display random articles correctly?

Question

PHP

Hello.
I want to display other random articles on the article page, I did it as follows:

$randomId = [];

$res = $dbh->query("SELECT * FROM goods WHERE id");
foreach ($res as $key) {
     $randomId[] = $key["id"];
}

I entered all IDs with articles into an array and displayed random ones.
How correct is this approach and how much will it load the database?
ps I have 150 IDs (they don't go one by one)

Answer 1

1 request!
2. Option 2 (faster with a large number of entries): https://stackoverflow.com/a/4329447

Answer 2

SELECT * FROM `goods` ORDER BY RAND() LIMIT 10
Do you have more than 500 requests per second to the database? What load are we talking about?
