PHP 日期加减的类,很不错
2015-01-24信息快讯网
PHP中对日期操作的函数功能强大,下面的代码是PHP对日期加减的类,很不错,有需要的朋友可以用一下。
如何使用这个类呢?请看下面的演示:$temptime = time(); echo strftime ( "%Hh%M %A %d %b" , $temptime ); $date = new DateAccount(); $temptime = $date ->DateAdd( "n" ,50, $temptime ); echo "<p>" ; echo strftime ( "%Hh%M %A %d %b" , $temptime );
$temptime = time(); echo strftime( "%Hh%M %A %d %b",$temptime); $date = new DateAccount(); $temptime = $date->DateAdd("n" ,50,$temptime); echo "<p>"; echo strftime( "%Hh%M %A %d %b",$temptime);
如果一切顺利,你可以看到以下结果:
15h41 Saturday 03 Jun
16h31 Saturday 03 Jun
$currenttime = time(); echo "Current time: " . strftime ( "%Hh%M %A %d %b" , $currenttime ). "<br>" ; $date = new DateAccount(); $newtime = $date ->DateAdd ( "n" ,50 , $currenttime ); echo "Time plus 50 minutes: " . strftime ( "%Hh%M %A %d %b" , $newtime ). "<br>" ; $temptime = $date ->DateDiff ( "n" , $currenttime , $newtime ); echo "Interval between two times: " . $temptime ;
$currenttime = time(); echo "Current time: ". strftime("%Hh%M %A %d %b" ,$currenttime)."<br>"; $date = new DateAccount(); $newtime = $date->DateAdd ("n",50 ,$currenttime); echo "Time plus 50 minutes: ". strftime("%Hh%M %A %d %b" ,$newtime)."<br>"; $temptime = $date->DateDiff ("n",$currenttime ,$newtime); echo "Interval between two times: ".$temptime;
如果一切顺利,你可以看到以下结果:
Current time: 16h23 Saturday 03 Jun
Time plus 50 minutes: 17h13 Saturday 03 Jun
Interval between two times: 50
<?php class DateAccount{ function __construct(){ } function DateAdd ( $interval , $number , $date ) { $date_time_array = getdate ( $date ); $hours = $date_time_array [ "hours" ]; $minutes = $date_time_array [ "minutes" ]; $seconds = $date_time_array [ "seconds" ]; $month = $date_time_array [ "mon" ]; $day = $date_time_array [ "mday" ]; $year = $date_time_array [ "year" ]; switch ( $interval ) { case "yyyy" : $year += $number ; break ; case "q" : $month +=( $number *3); break ; case "m" : $month += $number ; break ; case "y" : case "d" : case "w" : $day += $number ; break ; case "ww" : $day +=( $number *7); break ; case "h" : $hours += $number ; break ; case "n" : $minutes += $number ; break ; case "s" : $seconds += $number ; break ; } $timestamp = mktime ( $hours , $minutes , $seconds , $month , $day , $year ); return $timestamp ; } function DateDiff ( $interval , $date1 , $date2 ) { $timedifference = $date2 - $date1 ; switch ( $interval ) { case "w" : $retval = bcdiv ( $timedifference ,604800); break ; case "d" : $retval = bcdiv ( $timedifference ,86400); break ; case "h" : $retval = bcdiv ( $timedifference ,3600); break ; case "n" : $retval = bcdiv ( $timedifference ,60); break ; case "s" : $retval = $timedifference ; break ; } return $retval ; } } ?>
