想把
//生成友好时间形式function friendly_date( $from ){ static $now = null; $now == null && $now = time(); ! is_numeric( $from ) && $from = strtotime( $from ); $seconds = $now - $from; $minutes = floor( $seconds / 60 ); $hours = floor( $seconds / 3600 ); $day = round( ( strtotime( date( 'y-m-d', $now ) ) - strtotime( date( 'y-m-d', $from ) ) ) / 86400 ); if( $seconds == 0 ){ return '刚刚'; } if( ( $seconds >= 0 ) && ( $seconds = 0 ) && ( $minutes = 0 ) && ( $hours 0 ) { return date( 'y-m-d', $from ); } switch( $day ){ case 0: return date( '今天h:i', $from ); break; case 1: return date( '昨天h:i', $from ); break; default: //$day += 1; return {$day} 天前; break; }}

放入函数库，怎么放呢

在app/helpers/(目录可以自己随便来) 下新建一个文件 functions.php
在functions.php 中加入这个方法
然后在
bootstrap/autoload.php 中添加
require __dir__.'/../app/helpers/functions.php';
或者在
composer.json 中的 autoload 下增加
files: [ app/helpers/functions.php]
...autoload: { classmap: [ database ], psr-4: { app\\: app/ }, files: [ app/helpers/functions.php ]},...
参考：creating a helpers file
自制函数一个，供大家参考和改进
