如何从Ramsey\Uuid\Codec\StringCodec中提取uuid?
How to extract uuid from Ramsey\Uuid\Codec\StringCodec?
到目前为止,从以下几行开始
$records = $this->entityManager->getRepository(Translation::class)->findBy([], ['id' => 'DESC'], 1, 0);
$uuid = $records[0]->getId();
我可以得到以下几行。
Ramsey\Uuid\Uuid {#131
#codec: Ramsey\Uuid\Codec\StringCodec {#86
-builder: Ramsey\Uuid\Builder\DefaultUuidBuilder {#383
-converter: Ramsey\Uuid\Converter\Number\DegradedNumberConverter {#390}
}
}
#fields: array:6 [
"time_low" => "1483fc71"
"time_mid" => "66e9"
"time_hi_and_version" => "4e21"
"clock_seq_hi_and_reserved" => "b9"
"clock_seq_low" => "50"
"node" => "c6e9e6405428"
]
#converter: Ramsey\Uuid\Converter\Number\DegradedNumberConverter {#390}
uuid: "1483fc71-66e9"
}
如何提取 uuid
?
class 实现了 PHP 的 __toString
方法,因此您可以将对象转换为字符串:
$uuid = (string) $records[0]->getId();
使用 Ramsey\Uuid\Uuid
您可以通过多种方式将 UUID 提取为字符串。基本方法是 Ramsey\Uuid\Uuid::toString()
,因此您的代码示例如下:
$uuid = $records[0]->getId()->toString();
对于命名约定,存在一些所有调用 Ramsey\Uuid\Uuid::toString()
:
的包装器方法
Ramsey\Uuid\Uuid::serialize()
Ramsey\Uuid\Uuid::jsonSerialize()
但是你当然可以将整个对象转换为字符串,就像之前提到的@iainn。
