我有以下日期数组

array(5) { 
    [0]=> string(19) "2012-06-11 08:30:49" 
    [1]=> string(19) "2012-06-07 08:03:54" 
    [2]=> string(19) "2012-05-26 23:04:04" 
    [3]=> string(19) "2012-05-27 08:30:00" 
    [4]=> string(19) "2012-06-08 08:30:55" 
}

并且想知道 最近的日期 ,如下所示:最接近今天的日期。

我该怎么做?

使用max()array_map()strtotime()

$max = max(array_map('strtotime', $arr));
echo date('Y-m-j H:i:s', $max); // 2012-06-11 08:30:49

执行循环,将值转换为日期,并将最新的值存储在var。

$mostRecent= 0;
foreach($dates as $date){
  $curDate = strtotime($date);
  if ($curDate > $mostRecent) {
     $mostRecent = $curDate;
  }
}
这样的事情......你明白了 如果你今天最想要的话:

$mostRecent= 0;
$now = time();
foreach($dates as $date){
  $curDate = strtotime($date);
  if ($curDate > $mostRecent && $curDate < $now) {
     $mostRecent = $curDate;
  }
}

按日期对数组排序,然后获取数组的前值。

$dates = array(5) { /** omitted to keep code compact */ }
$dates = array_combine($dates, array_map('strtotime', $dates));
arsort($dates);
echo $dates[0];

$dates = [
    "2012-06-11 08:30:49" 
    ,"2012-06-07 08:03:54" 
    ,"2012-05-26 23:04:04" 
    ,"2012-05-27 08:30:00" 
    ,"2012-06-08 08:30:55" 
];
echo date("Y-m-d g:i:s",max(array_map('strtotime',$dates)));

这就是我的变种。它适用于未来的日期。

$Dates = array( 
    "2012-06-11 08:30:49", 
    "2012-06-07 08:03:54", 
    "2012-05-26 23:04:04",
    "2012-05-27 08:30:00",
    "2012-06-08 08:30:55",
    "2012-06-12 07:45:45"
);
$CloseDate = array();
$TimeNow = time();
foreach ($Dates as $Date) {
  $DateToCompare = strtotime($Date);
  $Diff = $TimeNow - $DateToCompare;
  if ($Diff < 0) $Diff *= -1;
  if (count($CloseDate) == 0) {
    $CloseDate['Date'] = $Date;
    $CloseDate['Diff'] = $Diff;
    continue;
  }
  if ($Diff < $CloseDate['Diff']) {
    $CloseDate['Date'] = $Date;
    $CloseDate['Diff'] = $Diff;
  }
}

var_dump($CloseDate);

我相信,以下是查找最近日期的最短代码。您可以更改它以查找最近日期的索引或查找将来或过去的最近日期。

$Dates = array( 
"2012-06-11 08:30:49", 
"2012-06-07 08:03:54", 
"2012-05-26 23:04:04",
"2012-05-27 08:30:00",
"2012-06-08 08:30:55",
"2012-06-22 07:45:45"
);

$close_date = current($Dates);
foreach($Dates as $date)
    if( abs(strtotime('now') - strtotime($date)) < abs(strtotime('now') - strtotime($close_date)))
        $close_date = $date;

echo $close_date;

这是我的建议:

$most_recent = 0;

foreach($array as $key => $date){
    if( strtotime($date) < strtotime('now') && strtotime($date) > strtotime($array[$most_recent]) ){
        $most_recent = $key;
    }
}

print $array[$most_recent]; //prints most recent day

    "2012-05-27 08:30:00","2012-06-08 08:30:55" 
);

function getMostRecent($array){
    $current = date("Y-m-d h:i:s");
    $diff1 = NULL;
    $recent = NULL;
    foreach($array as $date){
        if($diff = strcmp($current,$date)){
            if($diff1 == NULL){
                $diff1 = $diff;
                $recent = $date;
            }
            else{
                if($diff < $diff1){
                    $diff1 = $diff;
                    $recent = $date;
                }
            }
        }
    }
    return $recent;
}

试试这个:

public function getLargerDate(array $datas) {
    $newDates = array();
    foreach($datas as $data){
        $newDates[strtotime($data)] = $data;
    }
    return $newDates[max(array_keys($newDates))];
}
