PHPは秒を時間（年、日、時、分、秒）に変換します

$t=1637544;

$d=Sec2Time($t);

$d は 0 年、18 日、22 時間、52 分 24 秒です

//秒を時間に変換します (年、日) 、時、分、秒)

<span>function</span> Sec2Time(<span>$time</span><span>){
    </span><span>if</span>(<span>is_numeric</span>(<span>$time</span><span>)){
    </span><span>$value</span> = <span>array</span><span>(
      </span>"years" => 0, "days" => 0, "hours" => 0,
      "minutes" => 0, "seconds" => 0,<span>
    );
    </span><span>if</span>(<span>$time</span> >= 31556926<span>){
      </span><span>$value</span>["years"] = <span>floor</span>(<span>$time</span>/31556926<span>);
      </span><span>$time</span> = (<span>$time</span>%31556926<span>);
    }
    </span><span>if</span>(<span>$time</span> >= 86400<span>){
