简短的函数。PHP 5.3及更高版本。可以采用strtotime可以理解的任何日期格式的可选第三个参数。如果end < start自动反转方向。

function getDatesFromRange($start, $end, $format='Y-m-d') {
    return array_map(function($timestamp) use($format) {
        return date($format, $timestamp);
    },
    range(strtotime($start) + ($start < $end ? 4000 : 8000), strtotime($end) + ($start < $end ? 8000 : 4000), 86400));
}

测试:

date_default_timezone_set('Europe/Berlin');
print_r(getDatesFromRange( '2016-7-28','2016-8-2' ));
print_r(getDatesFromRange( '2016-8-2','2016-7-28' ));
print_r(getDatesFromRange( '2016-10-28','2016-11-2' ));
print_r(getDatesFromRange( '2016-11-2','2016-10-28' ));
print_r(getDatesFromRange( '2016-4-2','2016-3-25' ));
print_r(getDatesFromRange( '2016-3-25','2016-4-2' ));
print_r(getDatesFromRange( '2016-8-2','2016-7-25' ));
print_r(getDatesFromRange( '2016-7-25','2016-8-2' ));

输出:

      $sStartDate = gmdate("Y-m-d", strtotime($sStartDate));  
      $sEndDate = gmdate("Y-m-d", strtotime($sEndDate));  

      // Start the variable off with the start date  
     $aDays[] = $sStartDate;  

     // Set a 'temp' variable, sCurrentDate, with  
     // the start date - before beginning the loop  
     $sCurrentDate = $sStartDate;

     }  

     // Once the loop has finished, return the  
     // array of days.  
     return $aDays;  
   }  

使用像

GetDays('2007-01-01', '2007-01-31'); 

我喜欢一句俏皮话!

我今天的php发现是array_push()返回数组中元素的新数量。

我设法检查结束日期匹配，增加$x，并在空while循环的两部分条件语句中推入新元素。

function getDatesFromRange($a,$b,$x=0,$dates=[]){
    while(end($dates)!=$b && $x=array_push($dates,date("Y-m-d",strtotime("$a +$x day"))));
    return $dates;
}
var_export(getDatesFromRange('2010-10-01','2010-10-05'));

本页上与我的最相似的函数是drolex的函数(如果你相信我的话，我是在写完我的函数之后才发现的)。我做了一些大范围和小范围的速度测试，他们似乎经常击败对方——所以我称他们为平等的表演者。以下是其他一些比较:

我们都使用date()、strtotime()和两个数组函数。 Drolex只用了三个变量，我用了同样的三个加上$x。 因为我的函数不需要将开始日期加载到$date数组中，所以我可以在函数参数中声明它并保留该行(与$x类似)。

**只是一些重要的说明:

1-日期字符串在被输入到函数之前必须经过验证。

2-上述函数只能处理向前移动的日期范围。 如果希望向后移动日期范围，只需反转函数调用中的日期顺序，并在$x=后面添加减号。(很狡猾，是吧?)

function getDatesFromRange($a,$b,$x=0,$dates=[]){
    while(end($dates)!=$b && $x=-array_push($dates,date("Y-m-d",strtotime("$a +$x day"))));
    return $dates;
}
var_export(getDatesFromRange('2010-10-05','2010-10-01'));

还有一个延伸/考虑……

想象一下，您有一个多文化(或草率)的用户群，您的函数必须能够以不同的有效格式接收开始和结束日期，并且您需要能够以任何有效格式输出数组?通过细微的调整，我提供了一个解决方案。

我所说的“有效”是指YYYY-MM-DD, MM/DD/YYY和DD-MM- yyyy，这些都是全球范围内非常流行的标准，如果需要另一种格式，那么可用性将归结为strtotime对它的理解。

这里是演示。

代码:

function getDatesFromRange($a,$b,$format='Y-m-d',$dates=[],$x=0){
    while(date($format,strtotime(end($dates)))!=date($format,strtotime($b)) && $x=array_push($dates,date($format,strtotime("$a +$x day"))));
    return $dates;
}

$formats=array("Computer"=>'Y-m-d',"American"=>'m/d/Y','Non-American'=>'d-m-Y');
$start='15-02-2017';    // Non-American formatted start date
$end='2017-02-27';  // Computer formatted start date
foreach($formats as $label=>$format){
    echo "<br>$label<br>";
    var_export(getDatesFromRange($start,$end,$format));
    echo "<br>";
}

输出

Computer
array ( 0 => '2017-02-15', 1 => '2017-02-16', 2 => '2017-02-17', 3 => '2017-02-18',
        4 => '2017-02-19', 5 => '2017-02-20', 6 => '2017-02-21', 7 => '2017-02-22',

        12 => '2017-02-27', )

American
array ( 0 => '02/15/2017', 1 => '02/16/2017', 2 => '02/17/2017', 3 => '02/18/2017',
        4 => '02/19/2017', 5 => '02/20/2017', 6 => '02/21/2017', 7 => '02/22/2017',
        8 => '02/23/2017', 9 => '02/24/2017', 10 => '02/25/2017', 11 => '02/26/2017',
        12 => '02/27/2017', )

Non-American
array ( 0 => '15-02-2017', 1 => '16-02-2017', 2 => '17-02-2017', 3 => '18-02-2017',
        4 => '19-02-2017', 5 => '20-02-2017', 6 => '21-02-2017', 7 => '22-02-2017',
        8 => '23-02-2017', 9 => '24-02-2017', 10 => '25-02-2017', 11 => '26-02-2017',
        12 => '27-02-2017', )

现在有些人不100%信任strtotime()，因为一些错误的行为。我想我曾经读到过，当试图从闰日跳过一个月时，它会出错。然而，除非有人能复制它来证明我是错的，否则当你只增加一天时，strtotime()永远不会让你失望。

这是非常灵活的。
