格式为“原始"在PHP中将字符串转换为Java UUID [英] Format "raw" string to Java UUID in PHP

问题描述

在PHP中，是否存在更有效，简化的方法，可以将格式"的Java UUID(不带破折号)转换为Java兼容格式(带破折号)，并且最终:我将如何做?

Is there a more effective, simplified means of converting a "formatted" Java UUID - without dashes - to a Java compatible format - with dashes - in PHP, and ultimately: How would I do it?

我有已经执行此操作的代码，但似乎并不专业，我认为它可能可以更有效地完成.

I have code that already performs this action, but it seems unprofessional and I feel that it could probably be done more effectively.

[... PHP code ...]
$uuido = $json['id'];

$uuidx = array();
$uuidx[0] = substr( $uuido, 0, 8 );
$uuidx[1] = substr( $uuido, 8, 4 );
$uuidx[2] = substr( $uuido, 12, 4);
$uuidx[3] = substr( $uuido, 16, 4);
$uuidx[4] = substr( $uuido, 20, 12);

$uuid = implode( "-", $uuidx );
[... PHP code ...]

Input:  f9e113324bd449809b98b0925eac3141
Output: f9e11332-4bd4-4980-9b98-b0925eac3141

$json['id']中的数据是从以下 Mojang配置文件API 调用的使用file_get_contents( $url )函数和json_decode( $file )结合使用，也可以通过cURL完成-但由于最终最终一次请求最多2048个配置文件的任何内容，因此我认为它会变慢.

The data from $json['id'] is called from the following Mojang Profile API using the file_get_contents( $url ) function combined with a json_decode( $file ), which could alternatively be done through cURL - but since it would eventually be requesting anything up to 2048 profiles at once, I figured it would become slow.

我确实通过以下

I do have my code in use, and public, through the following ProjectRogue Server Ping API, which usually contains a list of online players.

注意:有几个与此相关的问题，但据我所知，没有一个问题适用于PHP.我看过了.

Note: There are several questions related to this, but none apply to PHP as far as I am aware. I have looked.

我提到Java UUID，因为解析后的输出应有效地转换为Player UUID，以便在1.7.X之后在Spigot或Craftbukkit的基于Java的插件中使用.

I mention Java UUID as the parsed output should effectively translate to a Player UUID for use in a Java-Based plugin for Spigot or Craftbukkit after 1.7.X.

推荐答案

您的问题没有多大意义，但是假设您想以Java正确的格式读取UUID，则可以执行以下操作:

Your question doesn't make much sense but assuming you want to read the UUID in the correct format in Java you can do something like this:

import java.util.UUID;
class A
{
    public static void main(String[] args){


        String input = "f9e113324bd449809b98b0925eac3141";                         
        String uuid_parse = input.replaceAll(                                            
                        "(\\w{8})(\\w{4})(\\w{4})(\\w{4})(\\w{12})",                            
                        "$1-$2-$3-$4-$5");                                                      

        UUID uuid = UUID.fromString(uuid_parse);
        System.out.println(uuid);
    }
}

或者在PHP中，您可以执行以下操作:

Or in PHP you can do something like:

<?php 
    $UUID = "f9e113324bd449809b98b0925eac3141";
    $UUID = substr($UUID, 0, 8) . '-' . substr($UUID, 8, 4) . '-' . substr($UUID, 12, 4) . '-' . substr($UUID, 16, 4)  . '-' . substr($UUID, 20);
    echo $UUID;
?>

从fico7489借来的: https://stackoverflow.com/a/33484855/4195825

然后可以将其发送到Java，在其中可以使用fromtString()创建UUID对象.

And then you can send that to Java where you can create a UUID object using fromtString().
