php計算幾分鐘前、幾小時前、幾天前的幾個函數(shù)、類分享
一、函數(shù)實現(xiàn)
實例1:
function time_tran($the_time){
$now_time = date("Y-m-d H:i:s",time()+8*60*60);
$now_time = strtotime($now_time);
$show_time = strtotime($the_time);
$dur = $now_time - $show_time;
if($dur < 0){
return $the_time;
}else{
if($dur < 60){
return $dur.'秒前';
}else{
if($dur < 3600){
return floor($dur/60).'分鐘前';
}else{
if($dur < 86400){
return floor($dur/3600).'小時前';
}else{
if($dur < 259200){//3天內(nèi)
return floor($dur/86400).'天前';
}else{
return $the_time;
}
}
}
實例2:
function format_date($time){
$t=time()-$time;
$f=array(
'31536000'=>'年',
'2592000'=>'個月',
'604800'=>'星期',
'86400'=>'天',
'3600'=>'小時',
'60'=>'分鐘',
'1'=>'秒'
);
foreach ($f as $k=>$v) {
if (0 !=$c=floor($t/(int)$k)) {
return $c.$v.'前';
}
}
}
?>
實例3:
function formatTime($date) {
$str = '';
$timer = strtotime($date);
$diff = $_SERVER['REQUEST_TIME'] - $timer;
$day = floor($diff / 86400);
$free = $diff % 86400;
if($day > 0) {
return $day."天前";
}else{
if($free>0){
$hour = floor($free / 3600);
$free = $free % 3600;
if($hour>0){
return $hour."小時前";
}else{
if($free>0){
$min = floor($free / 60);
$free = $free % 60;
if($min>0){
return $min."分鐘前";
}else{
if($free>0){
return $free."秒前";
}else{
return '剛剛';
}
}
}else{
return '剛剛';
}
}
}else{
return '剛剛';
}
}
}
實例4:
function time_tran($the_time){
$now_time = date("Y-m-d H:i:s",time()+8*60*60);
$now_time = strtotime($now_time);
$show_time = strtotime($the_time);
$dur = $now_time - $show_time;
if($dur < 0){
return $the_time;
}else{
if($dur < 60){
return $dur.'秒前';
}else{
if($dur < 3600){
return floor($dur/60).'分鐘前';
}else{
if($dur < 86400){
return floor($dur/3600).'小時前';
}else{
if($dur < 259200){//3天內(nèi)
return floor($dur/86400).'天前';
}else{
return $the_time;
}
}
}
}
}
}
二、類的實現(xiàn)

}
}
}
//類的使用實例
