PHP function to generate v4 UUID

Question

So I\'ve been doing some digging around and I\'ve been trying to piece together a function that generates a valid v4 UUID in PHP. This is the closest I\'ve been able to come

Answer 1

How about using mysql to generate the uuid for you?

$conn = new mysqli($servername, $username, $password, $dbname, $port);

$query = 'SELECT UUID()';
echo $conn->query($query)->fetch_row()[0];
