Php computing several minutes ago, several hours ago, several days ago, several functions and classes sharing _ PHP Tutorial

Php computing shares several functions and classes several minutes ago, several hours ago, and a few days ago. I. function implementation example 1: Copy the code as follows: functiontime_tran ($ the_time) {$ now_timedate (Y-m-dH: I: s, time () + 8*60*60); $ now_timestrtotime ($ now_time); $ show_time 1. function implementation
Instance 1:

The code is as follows:

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. 'seconds ago ';
} Else {
If ($ dur <3600 ){
Return floor ($ dur/60). 'minute ago ';
} Else {
If ($ dur <86400 ){
Return floor ($ dur/3600). 'hour ago ';
} Else {
If ($ dur <259200) {// within 3 days
Return floor ($ dur/86400). 'Days ago ';
} Else {
Return $ the_time;
}
}
}

Instance 2:

The code is as follows:

Function format_date ($ time ){
$ T = time ()-$ time;
$ F = array (
'20140901' => 'year ',
'000000' => 'month ',
'20140901' => 'week ',
'20140901' => 'day ',
'000000' => 'Hourly ',
'60' => 'mine ',
'1' => 'second'
);
Foreach ($ f as $ k => $ v ){
If (0! = $ C = floor ($ t/(int) $ k )){
Return $ c. $ v. 'pre ';
}
}
}
?>

Instance 3:

The code is as follows:

Function formatTime ($ date ){
$ Str = '';
$ Timer = strtotime ($ date );
$ Diff = $ _ SERVER ['request _ time']-$ timer;
$ Day = floor ($ diff/86400 );
$ Free = $ diff % 86400;
If ($ day> 0 ){
Return $ day. "days ago ";
} Else {
If ($ free> 0 ){
$ Hour = floor ($ free/3600 );
$ Free = $ free % 3600;
If ($ hour> 0 ){
Return $ hour. "hours ago ";
} Else {
If ($ free> 0 ){
$ Min = floor ($ free/60 );
$ Free = $ free % 60;
If ($ min> 0 ){
Return $ min. "minutes ago ";
} Else {
If ($ free> 0 ){
Return $ free. "seconds ago ";
} Else {
Return 'gang ';
}
}
} Else {
Return 'gang ';
}
}
} Else {
Return 'gang ';
}
}
}

Instance 4:

The code is as follows:

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. 'seconds ago ';
} Else {
If ($ dur <3600 ){
Return floor ($ dur/60). 'minute ago ';
} Else {
If ($ dur <86400 ){
Return floor ($ dur/3600). 'hour ago ';
} Else {
If ($ dur <259200) {// within 3 days
Return floor ($ dur/86400). 'Days ago ';
} Else {
Return $ the_time;
}
}
}
}
}
}

II. implementation of classes

The code is as follows:

/*
* Author: Solon Ring
* Time: 2011-11-02
* Sending time calculation (year, month, day, hour, minute, second)
* $ Createtime can be the current time
* $ Gettime the time you want to upload
*/

Class Mygettime {

Function _ construct ($ createtime, $ gettime ){
$ This-> createtime = $ createtime;
$ This-> gettime = $ gettime;
}

Function getSeconds ()
{
Return $ this-> createtime-$ this-> gettime;
}

Function getMinutes ()
{
Return ($ this-> createtime-$ this-> gettime)/(60 );
}

Function getHours ()
{
Return ($ this-> createtime-$ this-> gettime)/(60*60 );
}

Function getDay ()
{
Return ($ this-> createtime-$ this-> gettime)/(60*60*24 );
}

Function getMonth ()
{
Return ($ this-> createtime-$ this-> gettime)/(60*60*24*30 );
}

Function getYear ()
{
Return ($ this-> createtime-$ this-> gettime)/(60*60*24*30*12 );
}

Function index ()
{
If ($ this-> getYear ()> 1)
{
If ($ this-> getYear ()> 2)
{
Return date ("Y-m-d", $ this-> gettime );
Exit ();
}
Return intval ($ this-> getYear (). "years ago ";
Exit ();
}

If ($ this-> getMonth ()> 1)
{
Return intval ($ this-> getMonth (). "months ago ";
Exit ();
}

If ($ this-> getDay ()> 1)
{
Return intval ($ this-> getDay (). "days ago ";
Exit ();
}

If ($ this-> getHours ()> 1)
{
Return intval ($ this-> getHours (). "hours ago ";
Exit ();
}

If ($ this-> getMinutes ()> 1)
{
Return intval ($ this-> getMinutes (). "minutes ago ";
Exit ();
}

If ($ this-> getSeconds ()> 1)
{
Return intval ($ this-> getSeconds ()-1). "seconds ago ";
Exit ();
}

}

}
// Use instance of the class
/*
*
* Call class output method
*
* $ A = new Mygettime (time (), strtotime ('-25 month '));
* Echo iconv ('utf-8', 'gb2312 ', $ a-> index ())? Iconv ('utf-8', 'gb2312', $ a-> index (): iconv ('utf-8', 'gb2312', 'current ');
