![]() While (($row = $result->fetch_assoc()) != null) Luckily, we can use PHP to convert this binary form into a human readable string with the following logic (courtesy of a Stack Overflow post): $selectQuery = "SELECT * FROM `table1`" Unfortunately, when you select the data, you will get what appears to be junk out. We can create the table and then insert the data in binary format by using the unhex function after removing the hyphens: CREATE TABLE IF NOT EXISTS `table1` ( The easiest way to get started, would be to just use a varchar field like below CREATE TABLE `user`( $uuidString1 = Ramsey\Uuid\Uuid::uuid4()->toString() $factory->setRandomGenerator($generator) $codec = new Ramsey\Uuid\Codec\TimestampFirstCombCodec($factory->getUuidBuilder()) Installation composer require ramsey/uuid PHP - Doctrine ORM Good Practices and Tricks,This tutorial will show you how to generate UUIDs in PHP, and learn to store/retrieve them in either MySQL or PostgreSQL.,Please see the appendix if you would like grab an example script that uses all the code samples provided to test that using PHP or MySQL to convert the UUID string to binary and back again does work interchangeably.,Luckily, we can use PHP to convert this binary form into a human readable string with the following logic (courtesy of a Stack Overflow post):Ī universally unique identifier (UUID) is a 128 bit number used to identify information in computer systems.Īn example where you might see them is in Linux when you run blkid to identify your disks as shown below: /dev/sda1: UUID="039b9d65-373a-4a64-ba35-696198bc57f1" TYPE="ext4" PARTUUID="f7649116-01" There might be differences in the way this other language implements functions you rely on to generate key data, which lead to duplicate keys.,What is the best practices to generate UUID (PRIMARY KEY) You would then need to implement the same generator in that language. ,Let's say you decide to create an API in another language. ![]() Thats is my practise, for sure not the best. If I need the ID after interaction with a Database, I have had never problems in using a simple AutoIncrement ID. No expert, but if I use UUID or GUID I do it for scenarios, where I need an ID, before I interact with the Database. ![]() ![]() At the same time I would confirm that any pre-written UUID generators used be tested to confirm the that the least significant byte of the UUID changes faster than most significant byte (to accommodate database index clustering)., ![]() Using native database UUID functions will probably cause problems if the database is replicated. ![]()
