Question

如果我现在有了uuid就会出现像这样的42f704ab4ae141c78c185558f9447748但是有可能让它在这个42f704ab-4ae1-41c7-8c18-5558f9447748中串起来，所以在某些地方有破折号

<?php 
$playername = 'Vanture';
$url = "https://api.mojang.com/users/profiles/minecraft/" . urlencode($playername);
$result = file_get_contents($url);
$json = json_decode($result);
if ($json == NULL) {
    echo("NULL returned - probably invalid playername");
} else {
    $UUID = $json->id;
    echo "$UUID $playername";
}
?>

Answer 1

<?php 

//$UUID = 42f704ab-4ae1-41c7-8c18-5558f944774
$UUID = "42f704ab4ae141c78c185558f9447748";


$UUID = substr($UUID, 0, 8) . '-' . substr($UUID, 8, 4) . '-' . substr($UUID, 12, 4) . '-' . substr($UUID, 16, 4)  . '-' . substr($UUID, 20);
echo $UUID;

Answer 2

这是另一种方式：

$input = "42f704ab4ae141c78c185558f9447748";
$uuid = preg_replace("/(\w{8})(\w{4})(\w{4})(\w{4})(\w{12})/i", "$1-$2-$3-$4-$5", $input);
echo $uuid;

PHP添加破折号进行解码
