将 @ 开头的单词替换为推特链接


Replacing words starting with @ with a twitter link

我需要将文本中所有以@开头的单词替换为指向该Twitter帐户的相应链接。现在我正在使用这样的东西:

$tweet_text = preg_replace('/(@'w+)/', '<a href=''#''>'1</a>', $string);

这有效,但链接无处可去。我决定使用 strpos() 和 substr() 的组合来获取实际单词,然后能够链接到该 Twitter 帐户,但我想知道是否有更好的解决方案。有什么想法吗?

例子:

更换前:

'Imperfection is the new perfection... RT @xHausOfCandy: @katyperry i think your bottom teeth and your wonk eye make you even more adorable.'

更换后:

'Imperfection is the new perfection... RT <a href=''#''>@xHausOfCandy</a>: <a href=''#''>@katyperry</a> i think your bottom teeth and your wonk eye make you even more adorable.'

期望:

'Imperfection is the new perfection... RT <a href=''http://twitter.com/xHausOfCandy''>@xHausOfCandy</a>: <a href=''http://twitter.com/katyperry''>@katyperry</a> i think your bottom teeth and your wonk eye make you even more adorable.'

希望现在更清楚了!

将名称放在它自己的捕获组中,并在替换中引用它时使用 ''2。

$tweet_text = preg_replace('/(@('w+))/', '<a href="http://twitter.com/'2">'1</a>', $string);

您可以使用推特文本库

$string = 'Imperfection is the new perfection... RT @xHausOfCandy: @katyperry i think your bottom teeth and your wonk eye make you even more adorable.';
$tweet_text = preg_replace('/@('w+)/', '<a href="http://twitter.com/#'1">@'1</a>', $string);
