PHP がミリ秒のタイムスタンプを取得、PHP がミリ秒を取得_PHP チュートリアル-PHPチュートリアル-php.cn

PHP はミリ秒のタイムスタンプを取得し、php はミリ秒を取得します

PHP の time() 関数によって取得されるタイムスタンプは秒単位であることがわかっています。

ただし、フロントエンド JS によって取得されるタイムスタンプはミリ秒単位です。では、実際のアプリケーションでは、JS と PHP のタイムスタンプを統合する方法、つまり、PHP を使用してミリ秒のタイムスタンプを取得する方法については、次の例を参照してください。 <?php //函数,获取毫秒时间戳

3 番目のタイムスタンプ値が最初の 2 つよりわずかに大きいことがわかります。これはコードの実行にかかる時間であり、これは正常です。
