php实现比较两个字符串日期大小的方法,php字符串
本文实例讲述了php实现比较两个字符串日期大小的方法。分享给大家供大家参考。具体如下:
<?php function dateBDate($date1, $date2) { // 日期1是否大于日期2 $month1 = date("m", strtotime($date1)); $month2 = date("m", strtotime($date2)); $day1 = date("d", strtotime($date1)); $day2 = date("d", strtotime($date2)); $year1 = date("Y", strtotime($date1)); $year2 = date("Y", strtotime($date2)); $from = mktime(0, 0, 0, $month1, $day1, $year1); $to = mktime(0, 0, 0, $month2, $day2, $year2); if ($from > $to) { return true; } else { return false; } } ?> $date1 = "2009-10-13"; $date= mktime(0, 0, 0, date("m", strtotime($date1)), date("d", strtotime($date1)), date("Y", strtotime($date1)));
最终取得一个日期的 Unix 时间戳$date=1255392000。
很多时候做搜索的时候,搜索的时间不能大于当前日期,比较函数的写法大致和上面一个函数相同,具体如下:
function dateBCurrent($date){ //日期是否大于当前日期 $currentDate=date("Y-m-d"); //获取当前日期 $cYear=date("Y",strtotime($currentDate)); $cMonth=date("m",strtotime($currentDate)); $cDay=date("d",strtotime($currentDate)); $year=date("Y",strtotime($date)); $month=date("m",strtotime($date)); $day=date("d",strtotime($date)); $currentUnix=mktime(0,0,0,$cMonth,$cDay,$cYear); //当前日期的 Unix 时间戳 $dateUnix=mktime(0,0,0,$month,$day,$year); //待比较日期的 Unix 时间戳 if($dateUnix<=$currentUnix){ return true; }else{ return false; } }
希望本文所述对大家的php程序设计有所帮助。
