php-symfonyHow to generate UUIDs in PHP Symfony?

UUIDs (Universally Unique Identifiers) can be generated in PHP Symfony using the Ramsey\Uuid\Uuid class.

Example code

use Ramsey\Uuid\Uuid;

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

Output example

f3c9c2f2-f9f2-4f1f-b9f2-9f2f3f2f3f2f

Code explanation

• use Ramsey\Uuid\Uuid; - imports the Uuid class from the Ramsey\Uuid namespace
• Uuid::uuid4() - generates a version 4 (random) UUID
• $uuid4->toString() - returns the UUID as a string
