preg_replace() 的正则表达式推文 url 到 id 标签不起作用

Question

我有下一个字符串

 $string= "

https://twitter.com/AdamaUK_/status/1262730246668922885 

text

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

text

https://twitter.com/AdamaUK_/status/1262730246668922885

text

https://twitter.com/wheat_daddy/status/1262629949908885511?s=30

";

我想preg_replace()通过

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

      <div id='1262629949908885511'></div> text

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

        <div id='1262629949908885511'></div> text

到目前为止我试过没有成功

       $pattern = "/(?i)\b((?:https?:\/\/|www\d{0,3}[.]|twitter+[.][a-z]{2,4}\/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s`!()\[\]{};:'\".,<>?«»“”‘’]))/";

  function getTweet($string) {

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

        }

如何从推特网址获取 ID 并用标签成功替换它div？谢谢。

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$string= "https://twitter.com/AdamaUK_/status/1262730246668922885texthttps://twitter.com/wheat_daddy/status/1262629949908885511?s=20texthttps://twitter.com/AdamaUK_/status/1262730246668922885texthttps://twitter.com/wheat_daddy/status/1262629949908885511?s=30# Also caters for optional http, https and www:https://www.twitter.com/AdamaUK_/status/1262730246668922885texthttp://www.twitter.com/AdamaUK_/status/1262730246668922885texthttp://twitter.com/AdamaUK_/status/1262730246668922885textwww.twitter.com/AdamaUK_/status/1262730246668922885texttwitter.com/AdamaUK_/status/1262730246668922885text";$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&nbsp;<div id='1262730246668922885'></div>text<div id='1262629949908885511'></div>text<div id='1262730246668922885'></div>text<div id='1262629949908885511'></div># Also caters for optional http, https and www:<div id='1262730246668922885'></div>text<div id='1262730246668922885'></div>text<div id='1262730246668922885'></div>text<div id='1262730246668922885'></div>text<div id='1262730246668922885'></div>textVersion where the text is inside the div (Just thinking <div id='1262730246668922885'>text</div> is better than <div id='1262730246668922885'></div> text)<div id='1262730246668922885'>text</div><div id='1262629949908885511'>text</div><div id='1262730246668922885'>text</div><div id='1262629949908885511'></div># Also caters for optional http, https and www:<div id='1262730246668922885'>text</div><div id='1262730246668922885'>text</div><div id='1262730246668922885'>text</div><div id='1262730246668922885'>text</div><div id='1262730246668922885'>text</div>

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

Answer 3

为什么这么复杂？$pattern&nbsp;=&nbsp;'#https?:\/\/|www\d{0,3}[.]|twitter\.com\/([^\/]+)\/status\/(.+)#';$1 将是用户名，$2 是状态 ID。
