简介： PHP/Python/js/Golang/Java：时间转为人类可读的字符串格式：刚刚、几分钟前、几小时前、几天前

将时间转换为为刚刚、几分钟前、几小时前、几天前，有两种思路：

例如

2000-01-01 23:00:00  （需要格式化的时间）
2000-01-02 01:00:00   (此刻)

1、按照天、时、分逐个比较：不看时分秒，就是1天前

2、按照时间戳毫秒之差：要看时分秒，就是2小时前

为了更精确，本例采用方式2：按照时间戳毫秒之差的思路实现

PHP 代码实现

<?php
/**
 * @param $time_value int|string 时间戳
 * @return false|string
 *
 * 时间格式化为：
 * 刚刚
 * 1分钟前-56分钟前
 * 1小时前-23小时前
 * 1天前-7天前
 * 2022-10-09 13:33
 */
function timeForHuman($time_value)
{
    // 兼容传入字符串
    if (is_string($time_value)) {
        $time_value = strtotime($time_value);
    }
    $second = 1;
    $minute = $second * 60;
    $hour   = $minute * 60;
    $day    = $hour * 24;
    $day_8  = $day * 8;
    $now_time = time();
    $duration = $now_time - $time_value;
    if ($duration < $minute) {
        return '刚刚';
    } else if ($duration < $hour) {
        return floor($duration / $minute) . '分钟前';
    } elseif ($duration < $day) {
        return floor($duration / $hour) . '小时前';
    } else if ($duration < $day_8) {
        return floor($duration / $day) . '天前';
    } else {
        return date("Y-m-d H:i", $time_value);
    }
}

测试示例

$now_time = time();
$now_str  = date('Y-m-d H:i:s', $now_time);
echo $now_time . PHP_EOL;
// 1665381270
echo $now_str . PHP_EOL;
// 2022-10-10 13:54:30
echo timeForHuman($now_time) . PHP_EOL;
// 刚刚
echo timeForHuman($now_str) . PHP_EOL;
// 刚刚
echo timeForHuman('2022-10-10 13:33:11') . PHP_EOL;
// 21分钟前

JavaScript实现版本

/**
 * 格式化时间为人类可读的字符串格式
 * @param {number|string|Date} time_value 13位时间戳
 * @returns {string}
 *
 * 时间格式化为：
 * 刚刚
 * 1分钟前-56分钟前
 * 1小时前-23小时前
 * 1天前-7天前
 * 2022-10-09 13:33
 */
function timeForHuman(time_value) {
  // 兼容其他类型的参数
  if (typeof time_value != 'number') {
    time_value = Date.parse(time_value)
  }
  // 进制转换
  let millisecond = 1
  let second = millisecond * 1000
  let minute = second * 60
  let hour = minute * 60
  let day = hour * 24
  let day_8 = day * 8
  now_time = Date.now()
  duration = now_time - time_value
  if (duration < minute) {
    return '刚刚'
  } else if (duration < hour) {
    return Math.floor(duration / minute) + '分钟前'
  } else if (duration < day) {
    return Math.floor(duration / hour) + '小时前'
  } else if (duration < day_8) {
    return Math.floor(duration / day) + '天前'
  } else {
    let date = new Date(time_value)
    return [
      [
        date.getFullYear(),
        ('0' + (date.getMonth() + 1)).slice(-2),
        ('0' + date.getDate()).slice(-2),
      ].join('-'),
      [
        ('0' + date.getHours()).slice(-2),
        ('0' + date.getMinutes()).slice(-2),
      ].join(':'),
    ].join(' ')
  }
}

测试

console.log(new Date());
// 2022-10-12T02:45:06.286Z
console.log(timeForHuman(new Date()))
// 刚刚
console.log(timeForHuman(1635476685643))
// 2021-10-29 11:04
console.log(timeForHuman('2021-10-29T03:04:45.640Z'))
// 2021-10-29 11:04
console.log(timeForHuman('2022-10-12'))
// 2小时前

Python实现版本

    second = 1

示例

print(time_for_human(1665381270))
# 2天前
print(time_for_human(datetime.now()))
# 刚刚
print(time_for_human(time.time() - 100))
# 1分钟前
print(time_for_human('2022-10-10 13:33:11'))
# 2天前

Golang代码实现

package timeutil
import (
  "fmt"
  "time"
)
// 格式化
const DATE_LAYOUT = "2006-01-02"
// 以秒为基本单位的时间枚举常量
const (
  SECOND = 1
  MINUTE = SECOND * 60
  HOUR   = MINUTE * 60
  DAY    = HOUR * 24
  DAY_8  = DAY * 8
)
/**
* 格式化日期
* timeValue 10位时间戳
 */
func TimeForHuman(timeValue int64) string {
  nowTime := time.Now().Unix()
  diffTime := nowTime - timeValue
  if diffTime <= MINUTE {
    return "刚刚"
  } else if diffTime < HOUR {
    return fmt.Sprintf("%d分钟前", int(diffTime/MINUTE))
  } else if diffTime <= DAY {
    return fmt.Sprintf("%d小时前", int(diffTime/HOUR))
  } else if diffTime <= DAY_8 {
    return fmt.Sprintf("%d天前", int(diffTime/DAY))
  } else {
    return time.Unix(timeValue, 0).Format(DATE_LAYOUT)
  }

  "fmt"
  "testing"
  "time"
)
