请帮我编写 php 代码

Answer 1

这应该可以帮助您开始:

function convert_date($hit)
{
    $date = DateTime::createFromFormat("y-m-d", $hit[0]);

    if (!$date) //invalid date supplied, return original string
        return $hit[0]; 

    return $date->format("jS F Y");
}

$string = "this is my message in 12-10-12, Orlando or maybe 13-11-21";
$string = preg_replace_callback("~(\d{2}-\d{2}-\d{2})~", "convert_date", $string);
echo $string; //this is my message in 12th October 2012, Orlando or maybe 21st November 2013

看看php date modifiers ，DateTime extension和 preg_replace_callback欲了解更多信息。
