PHP获取毫秒时间戳

时间:2021-07-01 10:21:17 帮助过:16人阅读

我们知道,PHP中time()函数获取的时间戳,其单位是秒.

但是,前端JS获取的时间戳,单位是毫秒.

那么,在实际应用中,如何将JS和PHP的时间戳统一,即如何使用PHP获取毫秒时间戳呢,请看下例:

php

//函数,获取毫秒时间戳

function getMillisecond() {

list($t1, $t2) = explode(' ', microtime());

return (float)sprintf('%.0f', (floatval($t1) + floatval($t2)) * 1000);

}

//上面的函数是百度出来的,我刚开始看着也不是很明白.

//现分开详细讲解如下:

function getMillisecond_new(){

//使用microtime()获取微秒时间戳,格式(中间空格隔开):'秒的小数部分 秒的整数部分',例如'0.69718900 1420440552'

//将微秒字符串explode炸开,接收$t1=0.69718900 $t2=1420440552

list($t1, $t2) = explode(' ', microtime());

//转成浮点数

$t1=floatval($t1);

$t2=floatval($t2);

//相加×1000

$total=( $t1+ $t2) * 1000;

//四舍五入

$total=round($total,0);

//返回结果

return $total;

}

echo getMillisecond()," PHP毫秒-getMillisecond()
";

echo getMillisecond_new().' PHP毫秒-getMillisecond_new()';

/*

* 思路:

* 1.使用microtime()获取微秒时间戳,格式:0.69718900 1420440552

* 2.前后两部分相加×1000,然后四舍五入round($float,0)

* 秒time()-->毫秒-->微秒microtime(),两两之间是1000进制

* 这样,就可以与前端JS的时间戳保持一致

* JS : new Date().getTime()获得毫秒时间戳
