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 ) && ( $seconds <= 60 ) ){
return "{$seconds}秒前";
}
if( ( $minutes >= 0 ) && ( $minutes <= 60 ) ){
return "{$minutes}分钟前";
}
if( ( $hours >= 0 ) && ( $hours <= 24 ) ){
return "{$hours}小时前";
}
if( ( date( 'Y' ) - date( 'Y', $from ) ) > 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
