PHP 格式化时间显示刚刚、几分钟前、昨天、前天

PetitQ HTML/CSS 2019-3-12 2.33K 0 1

PHP 把时间转换为友好时间段，如刚刚、几分钟前、几小时前、几天前的简单函数代码。通过把时间格式转换为时间戳，并把当前的时间戳减去之前时间的时间戳，相减后的时间戳除以相对应的秒数得到刚刚、几分钟前、几小时前、几天前的展示，需要的朋友可以参考下：

```
//时间格式化（时间戳）
```
```
function uc_time_ago($ptime) {
```
```
	date_default_timezone_set('PRC');
```
```
	//$ptime = strtotime($ptime);
```
```
	$etime = time() - $ptime;
```
```
	switch ($etime){
```
```
		case $etime <= 60:
```
```
			$msg = '刚刚';
```
```
			break;
```

		case $etime > 60 && $etime <= 60 * 60:

			$msg = floor($etime / 60) . ' 分钟前';

```
			break;
```

		case $etime > 60 * 60 && $etime <= 24 * 60 * 60:

			$msg = date('Ymd',$ptime)==date('Ymd',time()) ? '今天 '.date('H:i',$ptime) : '昨天 '.date('H:i',$ptime);

```
			break;
```

		case $etime > 24 * 60 * 60 && $etime <= 2 * 24 * 60 * 60:

			$msg = date('Ymd',$ptime)+1==date('Ymd',time()) ? '昨天 '.date('H:i',$ptime) : '前天 '.date('H:i',$ptime);

```
			break;
```

		case $etime > 2 * 24 * 60 * 60 && $etime <= 12 * 30 * 24 * 60 * 60:

			$msg = date('Y',$ptime)==date('Y',time()) ? date('m-d H:i',$ptime) : date('Y-m-d H:i',$ptime);

```
			break;
```

		default: $msg = date('Y-m-d H:i',$ptime);

```
	}
```
```
	return $msg;
```
```
}
```
