如何在php中更改日期格式2015年12月21日至21-12-2015

Question

我想更改日期格式，如

$date ="21 dec '15";

到

$date ="21-12-2015";

如何在php中实现。

Answer 1

$date = DateTime::createFromFormat('!m', $result['month']);

echo $date->format('F');

F stands for "month name",

Answer 2

使用此

$date = "21 dec '2015"; #your date 
$replaced_date = str_replace("'","",$date);
$new = date_create($replaced_date);
$new_date = date_format($new, "d-m-Y"); # restructer the date
echo $new_date ;

Answer 3
