php格式化时间戳显示友好的时间实现思路及代码_PHP
在项目中时间一律显示为2014-10-20 10:22显得很呆板。在微博、QQ空间等网站通常会显示为几秒前,几分钟前,几小时前等容易阅读的时间,我们称之为友好的时间格式。那么用php怎么实现呢?
大体思路如下:
如果是跨年并且大于3天就显示为具体的时间
如果是今天的
如果是一分钟内则显示几秒之前
如果是一小时内则显示几分钟前
如果是当天且大于一小时则显示为几小时前
如果是昨天则显示为昨天几点
如果是前天则显示为前天几点
如果大于三天(没有跨年)则显示为几月几号
根据以上思路就不难写出实现代码了:
实现代码如下:
//格式化友好显示时间 function formatTime($time){ $now=time(); $day=date('Y-m-d',$time); $today=date('Y-m-d'); $dayArr=explode('-',$day); $todayArr=explode('-',$today); //距离的天数,这种方法超过30天则不一定准确,但是30天内是准确的,因为一个月可能是30天也可能是31天 $days=($todayArr[0]-$dayArr[0])*365+(($todayArr[1]-$dayArr[1])*30)+($todayArr[2]-$dayArr[2]); //距离的秒数 $secs=$now-$time; if($todayArr[0]-$dayArr[0]>0 && $days>3){//跨年且超过3天 return date('Y-m-d',$time); }else{ if($days<1){//今天 if($secs<60)return $secs.'秒前'; elseif($secs<3600)return floor($secs/60)."分钟前"; else return floor($secs/3600)."小时前"; }else if($days<2){//昨天 $hour=date('h',$time); return "昨天".$hour.'点'; }elseif($days<3){//前天 $hour=date('h',$time); return "前天".$hour.'点'; }else{//三天前 return date('m月d号',$time); } } }

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
