php 获取当前时间戳、日期并精确到毫秒

首先，我们封装一个获取时间戳的方法：

第一种方法：时间戳13位

/**
 * 获取时间戳到毫秒
 * @return bool|string
 */
public static function getMillisecond(){
    list($msec, $sec) = explode(&#39; &#39;, microtime());
    $msectime =  (float)sprintf(&#39;%.0f&#39;, (floatval($msec) + floatval($sec)) * 1000);
    return $msectimes = substr($msectime,0,13);
}

其次，调用这个方法，并打印结果：

PHP gets the current timestamp, date and is accurate to milliseconds (three methods)

看看结果：

PHP gets the current timestamp, date and is accurate to milliseconds (three methods)

成功获取到了，时间戳且精确到了毫秒！---- 13位，自己数数。

第二种方法：时间戳浮点型

/**
 * 时间戳 - 精确到毫秒
 * @return float
 */
public static function getMillisecond() {
    list($t1, $t2) = explode(&#39; &#39;, microtime());
    return (float)sprintf(&#39;%.0f&#39;,(floatval($t1)+floatval($t2))*1000);
}

调用：

//时间戳
$_t  = self::getMillisecond();
dd($_t);

打印结果：

PHP gets the current timestamp, date and is accurate to milliseconds (three methods)

第三种方法：14位年月日时分秒+3位毫秒数

/**
 * 年月日、时分秒 + 3位毫秒数
 * @param string $format
 * @param null $utimestamp
 * @return false|string
 */
public static function ts_time($format = &#39;u&#39;, $utimestamp = null) {
    if (is_null($utimestamp)){
        $utimestamp = microtime(true);
    }
 
    $timestamp = floor($utimestamp);
    $milliseconds = round(($utimestamp - $timestamp) * 1000);
 
    return date(preg_replace(&#39;`(?<!\\\\)u`&#39;, $milliseconds, $format), $timestamp);
}

调用：

/**
     * @param array       $reqData 接口传递的参数
     * @param PayMerchant $payConf object PayMerchant类型的对象
     * @return array
     */
    public static function getAllInfo($reqData, PayMerchant $payConf)
    {
        /**
         * 参数赋值，方法间传递数组
         */
        $order     = $reqData[&#39;order&#39;];
        $amount    = $reqData[&#39;amount&#39;];
        $bank      = $reqData[&#39;bank&#39;];
        $ServerUrl = $reqData[&#39;ServerUrl&#39;]; // 异步通知地址
        $returnUrl = $reqData[&#39;returnUrl&#39;]; // 同步通知地址
        //TODO: do something
        $data = array(
            &#39;mchntCode&#39;         => $payConf[&#39;business_num&#39;],
            &#39;channelCode&#39;       => $bank,
            &#39;mchntOrderNo&#39;      => $order,
            &#39;orderAmount&#39;       => $amount * 100,
            &#39;clientIp&#39;          => request()->ip(),
            &#39;subject&#39;           => &#39;goodsName&#39;,
            &#39;body&#39;              => &#39;goodsName&#39;,
            &#39;notifyUrl&#39;         => $ServerUrl,
            &#39;pageUrl&#39;           => $returnUrl,
            &#39;orderTime&#39;         => date(&#39;YmdHis&#39;),
            &#39;description&#39;       => $order,
            &#39;orderExpireTime&#39;   => date(&#39;YmdHis&#39;,time()+300),
            &#39;ts&#39;                => self::ts_time(&#39;YmdHisu&#39;),
