下面是一个函数,它将从两个方向返回日期范围,适用于PHP >=5.2.2:
function createRange($start, $end, $format = 'Y-m-d') {
$start = new DateTime($start);
$end = new DateTime($end);
$invert = $start > $end;
$dates = array();
$dates[] = $start->format($format);
while ($start != $end) {
$start->modify(($invert ? '-' : '+') . '1 day');
$dates[] = $start->format($format);
}
return $dates;
}
使用的例子:
print_r(createRange('2010-10-01', '2010-10-05'));
/*Array
(
[0] => 2010-10-01
[1] => 2010-10-02
[2] => 2010-10-03
[3] => 2010-10-04
[4] => 2010-10-05
)*/
print_r(createRange('2010-10-05', '2010-10-01', 'j M Y'));
/*Array
(
[0] => 5 Oct 2010
[1] => 4 Oct 2010
[2] => 3 Oct 2010
[3] => 2 Oct 2010
[4] => 1 Oct 2010
)*/
demo
function createDateRangeArray($start, $end) {
// Modified by JJ Geewax
$range = array();
if (is_string($start) === true) $start = strtotime($start);
if (is_string($end) === true ) $end = strtotime($end);
if ($start > $end) return createDateRangeArray($end, $start);
do {
$range[] = date('Y-m-d', $start);
$start = strtotime("+ 1 day", $start);
}
while($start < $end);
return $range;
}

// Specify the start date. This date can be any English textual format
$date_from = "2018-02-03";
$date_from = strtotime($date_from); // Convert date to a UNIX timestamp
// Specify the end date. This date can be any English textual format
$date_to = "2018-09-10";
$date_to = strtotime($date_to); // Convert date to a UNIX timestamp
// Loop from the start date to end date and output all dates inbetween
for ($i=$date_from; $i<=$date_to; $i+=86400) {
echo date("Y-m-d", $i).'<br />';
}
function GetDays($sStartDate, $sEndDate){
// Firstly, format the provided dates.
// This function works best with YYYY-MM-DD
// but other date formats will work thanks
// to strtotime().
$sStartDate = gmdate("Y-m-d", strtotime($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 = $sStartDate;
// While the current date is less than the end date
while($sCurrentDate < $sEndDate){
// Add a day to the current date
$sCurrentDate = gmdate("Y-m-d", strtotime("+1 day", strtotime($sCurrentDate)));
// Add this new day to the aDays array
$aDays[] = $sCurrentDate;
}
// 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',
8 => '2017-02-23', 9 => '2017-02-24', 10 => '2017-02-25', 11 => '2017-02-26',
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',

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。
