Question

我希望正则表达式只用tweet id替换。我试过下面的正则表达式，但不起作用。

$string = "The meeting, which was also attended by Chief Bisi Akande, held at the Abuja House in London, a tweet from the presidency revealed.

[twt]https://twitter.com/NGRPresident/status/829704039952740352[/twt]

[twt]https://mobile.twitter.com/NGRPresident/status/829713387001114625[/twt]

President Buhari has been away from Nigeria since January when he departed for a 10-day medical vacation.";
$regex = '/\[twt\]\/https?://twitter\.com/(?:\#!/)?(\w+)/status(es)?/(\d+)[\/twt\]/';
$string = preg_replace("$regex", '$3', $string);
echo $string;'

我希望结果输出;
