php-laravelHow do I generate a UUID using Laravel and PHP?

UUID stands for Universally Unique Identifier and is a 128-bit number used to identify information in computer systems. In Laravel and PHP, UUIDs can be generated using the Ramsey\Uuid\Uuid class.

Example code

use Ramsey\Uuid\Uuid;

$uuid = Uuid::uuid4();
echo $uuid->toString();

Output example

d6e3c3d8-e7b3-4caf-8c3f-7bb3b881b863

Code explanation

• use Ramsey\Uuid\Uuid; - This line imports the Uuid class from the ramsey/uuid package.
• $uuid = Uuid::uuid4(); - This line generates a version 4 UUID.
• echo $uuid->toString(); - This line outputs the UUID as a string.
