这篇文章主要介绍了php实现的DateDiff和DateAdd时间函数代码分享,DateDiff用来计算两个时间的间隔,DateAdd用来对两个时间进行相加,需要的朋友可以参考下
扩展php中的时间函数DateDiff和DateAdd
- function DateDiff($part, $begin, $end)
- {
- $diff = strtotime($end) - strtotime($begin);
- switch($part)
- {
- case "y": $retval = bcdiv($diff, (60 * 60 * 24 * 365)); break;
- case "m": $retval = bcdiv($diff, (60 * 60 * 24 * 30)); break;
- case "w": $retval = bcdiv($diff, (60 * 60 * 24 * 7)); break;
- case "d": $retval = bcdiv($diff, (60 * 60 * 24)); break;
- case "h": $retval = bcdiv($diff, (60 * 60)); break;
- case "n": $retval = bcdiv($diff, 60); break;
- case "s": $retval = $diff; break;
- }
- return $retval;
- }
- function DateAdd($part, $number, $date)
- {
- $date_array = getdate(strtotime($date));
- $hor = $date_array["hours"];
- $min = $date_array["minutes"];
- $sec = $date_array["seconds"];
- $mon = $date_array["mon"];
- $day = $date_array["mday"];
- $yar = $date_array["year"];
- switch($part)
- {
- case "y": $yar += $number; break;
- case "q": $mon += ($number * 3); break;
- case "m": $mon += $number; break;
- case "w": $day += ($number * 7); break;
- case "d": $day += $number; break;
- case "h": $hor += $number; break;
- case "n": $min += $number; break;
- case "s": $sec += $number; break;
- }
- return date("Y-m-d H:i:s", mktime($hor, $min, $sec, $mon, $day, $yar));
- }
- Function DateAdd($part, $n, $date)
- {
- switch($part)
- {
- case "y": $val = date("Y-m-d H:i:s", strtotime($date ." +$n year")); break;
- case "m": $val = date("Y-m-d H:i:s", strtotime($date ." +$n month")); break;
- case "w": $val = date("Y-m-d H:i:s", strtotime($date ." +$n week")); break;
- case "d": $val = date("Y-m-d H:i:s", strtotime($date ." +$n day")); break;
- case "h": $val = date("Y-m-d H:i:s", strtotime($date ." +$n hour")); break;
- case "n": $val = date("Y-m-d H:i:s", strtotime($date ." +$n minute")); break;
- case "s": $val = date("Y-m-d H:i:s", strtotime($date ." +$n second")); break;
- }
- return $val;
- }
