如何使用 PHP 获取特定日期的日期

Question

我想得到 10 月 22 日的那一天（星期日、星期一……）。我该怎么做？

Answer 1

You can use the date function. I'm using strtotime to get the timestamp to that day ; there are other solutions, like mktime , for instance.

For instance, with the 'D' modifier, for the textual representation in three letters :

$timestamp = strtotime('2009-10-22');

$day = date('D', $timestamp);
var_dump($day);

You will get :

string 'Thu' (length=3)

And with the 'l' modifier, for the full textual representation :

$day = date('l', $timestamp);
var_dump($day);

You get :

string 'Thursday' (length=8)

Or the 'w' modifier, to get to number of the day (0 to 6, 0 being sunday, and 6 being saturday) :

$day = date('w', $timestamp);
var_dump($day);

You'll obtain :

string '4' (length=1)

Answer 2

$date = '2014-02-25';
date('D', strtotime($date));

Answer 3

$datetime = DateTime::createFromFormat('Ymd', '20151102');

echo $datetime->format('D');

Answer 4

$date = '2009-10-22';
$sepparator = '-';
$parts = explode($sepparator, $date);
$dayForDate = date("l", mktime(0, 0, 0, $parts[1], $parts[2], $parts[0]));

Answer 5

$date = strtotime('2016-2-3');
$date = date('l', $date);
var_dump($date)

(i added format 'l' so it will return full name of day)

Answer 6

$timestamp = strtotime('2009-10-22');
$day = date('D', $timestamp);
var_dump($day);
