如何将日期和时间字符串转换成不同的格式?

尝试

$dt = '2015-04-15 13:22:58';

echo date("jS F Y h:i a", strtotime($dt)); 
//Result is 15th April 2015 01:22 pm

echo date("jS F Y g:i a", strtotime($dt)); 
// Result is 15th April 2015 1:22 pm

改变 "jS F Y" 到 "js F Y g:i a"

$dt = '2015-04-15 13:22:58';
echo date("jS F Y g:i a", strtotime($dt));

15th April 2015 1:22 pm

date_format 这样地。

echo date_format(strtotime($dt), "jS F Y g:i A");
