用于生成随机ID的PHP库，并避免像Nodejs帽子模块那样的冲突 - PHP library for Generating random IDs and avoid collisions like Nodejs hat module

PHP library for Generating random IDs and avoid collisions like Nodejs hat module

是否有任何库可用于在PHP中生成随机ID。在 Nodejs 中，我们有hat模块来生成随机 ID

节点 js.

var hat = require('hat');
var rack = hat.rack();
console.log(rack());
console.log(rack());

任何 PHP 库？

使用生成唯一 ID 的uniqid()

试试这个：

<?php
echo uniqid().'<br>';
echo uniqid().'<br>';
echo uniqid().'<br>';
echo uniqid().'<br>';
?>

我推荐 https://github.com/ramsey/uuid

<?php
require 'vendor/autoload.php';
use Ramsey'Uuid'Uuid;
use Ramsey'Uuid'Exception'UnsatisfiedDependencyException;
try {
    // Generate a version 1 (time-based) UUID object
    $uuid1 = Uuid::uuid1();
    echo $uuid1->toString() . "'n"; // i.e. e4eaaaf2-d142-11e1-b3e4-080027620cdd
    // Generate a version 3 (name-based and hashed with MD5) UUID object
    $uuid3 = Uuid::uuid3(Uuid::NAMESPACE_DNS, 'php.net');
    echo $uuid3->toString() . "'n"; // i.e. 11a38b9a-b3da-360f-9353-a5a725514269
    // Generate a version 4 (random) UUID object
    $uuid4 = Uuid::uuid4();
    echo $uuid4->toString() . "'n"; // i.e. 25769c6c-d34d-4bfe-ba98-e0ee856f3e7a
    // Generate a version 5 (name-based and hashed with SHA1) UUID object
    $uuid5 = Uuid::uuid5(Uuid::NAMESPACE_DNS, 'php.net');
    echo $uuid5->toString() . "'n"; // i.e. c4a760a8-dbcf-5254-a0d9-6a4474bd1b62
} catch (UnsatisfiedDependencyException $e) {
    // Some dependency was not met. Either the method cannot be called on a
    // 32-bit system, or it can, but it relies on Moontoast'Math to be present.
    echo 'Caught exception: ' . $e->getMessage() . "'n";
}

请注意，通过随机生成 ID，总是有发生冲突的机会（即使它几乎等于 0）。

你应该擅长 GUIDS。

试试 uniqid（）。它基于microtime（）生成唯一标识符，并在Unix和Windows上运行。
