When the amount of concurrency is high, millisecond-level operations need to be enabled!

mysql Support:

PHP code implementation:

<?php
    $a =  get_msectime();
    $b = get_microtime_format($a*0.001);
    $c = get_data_format($b);
    echo $a;
    echo "<pre class="brush:php;toolbar:false">";
    echo $b;
    echo "<pre class="brush:php;toolbar:false">";
    echo $c;
    //返回当前的毫秒时间戳
    function get_msectime() {
        list($msec, $sec) = explode(&#39; &#39;, microtime());
        $msectime =  (float)sprintf(&#39;%.0f&#39;, (floatval($msec) + floatval($sec)) * 1000);
        return $msectime;
 
     }
     
     /** 
      *时间戳 转   日期格式 ： 精确到毫秒，x代表毫秒
      */
     function get_microtime_format($time)
     {  
        if(strstr($time,&#39;.&#39;)){
            sprintf("%01.3f",$time); //小数点。不足三位补0
            list($usec, $sec) = explode(".",$time);
            $sec = str_pad($sec,3,"0",STR_PAD_RIGHT); //不足3位。右边补0
        }else{
            $usec = $time;
            $sec = "000"; 
        }
        $date = date("Y-m-d H:i:s.x",$usec);
        return str_replace(&#39;x&#39;, $sec, $date);
     }
      /** 时间日期转时间戳格式，精确到毫秒，
      *     
      */
     function get_data_format($time)
     {
        list($usec, $sec) = explode(".", $time);
        $date = strtotime($usec);
        $return_data = str_pad($date.$sec,13,"0",STR_PAD_RIGHT); //不足13位。右边补0
        return $return_data;
