Answer 1

不确定这是否是您要找的，但我认为

<div id='1262730246668922885'>text</div>

比

<div id='1262730246668922885'></div> text

下面还根据要求删除了 ?s=20 。

这是我用来测试表达式的脚本：

<?php

$string= "

https://twitter.com/wheat_daddy/status/1262629949908885511?s=20

";

$pattern = "~(?:https?:\/\/)?(?:www\.)?twitter\.com\/[^\/]+/status/(\d+)(?:.+)?~";

echo preg_replace($pattern, "<div id='$1'></div>", $string);

echo "Version where the text is inside the div (Just thinking <div id='1262730246668922885'>text</div> is better than <div id='1262730246668922885'></div> text)";

$pattern = "~(?:https?:\/\/)?(?:www\.)?twitter\.com\/[^\/]+/status/(\d+)(?:.+)?\R(.+)?~m";

echo preg_replace($pattern, "<div id='$1'>$2</div>", $string);

?>

在命令行执行时的结果：

$ php -f test.php

Answer 2

可能有很多模式，取决于你的大脑是如何工作的。我只想寻找推特部分，然后在以下位置获取数字/status/：

$result = preg_replace('~https?://twitter\.com/.*?/status/(\d+).*~', "<div id='$1'></div>", $string);

Answer 3

为什么这么复杂？

$pattern = '#https?:\/\/|www\d{0,3}[.]|twitter\.com\/([^\/]+)\/status\/(.+)#';

$1 将是用户名，$2 是状态 ID。
