PHP Get time difference

PHP Gets the time difference, we are in the process of development, this is a frequently used function, for example, we want to check the data for a certain period, it is necessary to use this function.

Example one:

/** * Function: Get time difference * @param int $time * @return string time difference value */function trantime ($time) {    $rtime = date ("m-d h:i", $time); 
   $htime = Date ("H:i", $time);     $time = Time ()-$time;     if ($time <) {        $str = ' just ';    }    ElseIf ($time <) {        $min = floor ($time/60);        $str = $min. ' Minutes ago ';    }    ElseIf ($time < *) {        $h = floor ($time/(60*60));        $str = $h. ' Hour ago '. $htime;    }    ElseIf ($time < * 3) {        $d = floor ($time/(60*60*24));        if ($d ==1)           $str = ' Yesterday '. $rtime;        else           $str = ' The day before yesterday '. $rtime;    }    else {        $str = $rtime;    }    return $STR;}

Example two:

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 <) {     return $dur. ' seconds ago ';    } else{     if ($dur < 3600) {      return floor ($dur/60). ' Minutes ago ';     } else{      if ($dur < 86400) {       return floor ($dur/3600). ' Hours ago ';      } else{       if ($dur < 259200) {//3 days        return floor ($dur/86400). ' Days ago ';       } else{        return $the _time;}}}      

Example three:

function Format_date ($time) {    $t =time ()-$time;    $f =array (        ' 31536000 ' = ' year ',        ' 2592000 ' + ' month ', '        604800 ' + ' ' Week ',        ' 86400 ' and ' Day ',        ' 3600 ' = ' + ' hours ', ' + '        = ' minutes ',        ' 1 ' = ' s '    ;    foreach ($f as $k = + $v)    {        if (0! = $c =floor ($t/(int) $k)) {            return $c. $v. ' ago ';        }    }

Example four:

function Formattime ($date) {$str = '; $timer = Strtotime ($date); $diff = $_server[' Request_time ']-$timer; $day = Floor ($di ff/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 ' just ';}}} Else{return ' just ';}}} Else{return ' just ';}}}

Example five:

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 <) {    return $dur. ' seconds ago ';} else{    if ($dur < 3600) {   return floor ($dur/60). ' Minutes ago ';     } else{   if ($dur < 86400) {   return floor ($dur/3600). ' Hours ago ';    } else{   if ($dur < 259200) {//3 days       return floor ($dur/86400). ' Days ago ';   } else{       return $the _time;}}}}}    

Example SIX:

/* * Author:solon Ring * time:2011-11-02 * bo Time calculation (year, month, day, hour, minute, seconds) * $createtime can be the current time * $gettime you want to pass in the time */class Mygetti            Me{function __construct ($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 () &G T           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 instances of the}}}//class/* * Call class Output mode * * $a = new Mygettime (Time (), Strtotime (' -25 month ')); * ECHo iconv (' utf-8 ', ' gb2312 ', $a->index ())?
