Add links to PHP that pulls latest tweet from Twitter Account - php

Question

I've got a nice little twitter widget on my website that was created using php. I'd like to be able to make sure that when a link appears it is clickable or when I #reply someone it links to their profile. Any help is greatly appreciated.
<?php
function getTwitterStatus($userid){
$url = "http://twitter.com/statuses/user_timeline/$userid.xml?count=1";
$xml = simplexml_load_file($url) or die("could not connect");
foreach($xml->status as $status){
$text = $status->text;
}
echo $text;
}
getTwitterStatus("UltanKC");
?>

Answer 1

I have a function which I use for this - it will make links for URLs, twitter user names and twitter hashtags.
function auto_link_twitter ($text)
{
// properly formatted URLs
$urls = "/(((http[s]?:\/\/)|(www\.))?(([a-z][-a-z0-9]+\.)?[a-z][-a-z0-9]+\.[a-z]+(\.[a-z]{2,2})?)\/?[a-z0-9._\/~#&=;%+?-]+[a-z0-9\/#=?]{1,1})/is";
$text = preg_replace($urls, " <a href='$1'>$1</a>", $text);
// URLs without protocols
$text = preg_replace("/href=\"www/", "href=\"http://www", $text);
// Twitter usernames
$twitter = "/#([A-Za-z0-9_]+)/is";
$text = preg_replace ($twitter, " <a href='https://twitter.com/$1'>#$1</a>", $text);
// Twitter hashtags
$hashtag = "/#([A-Aa-z0-9_-]+)/is";
$text = preg_replace ($hashtag, " <a href='https://twitter.com/hashtag/$1'>#$1</a>", $text);
return $text;
}
to use it with your code, edit the line which echoes out the status:
echo auto_link_twitter ($text);

Looks like this one is pretty comprehensive via googling 'twitter php automatic links'
(from http://www.snipe.net/2009/09/php-twitter-clickable-links/):
function twitterify($ret) {
$ret = preg_replace("#(^|[\n ])([\w]+?://[\w]+[^ \"\n\r\t< ]*)#", "\\1\\2", $ret);
$ret = preg_replace("#(^|[\n ])((www|ftp)\.[^ \"\t\n\r< ]*)#", "\\1\\2", $ret);
$ret = preg_replace("/#(\w+)/", "#\\1", $ret);
$ret = preg_replace("/#(\w+)/", "#\\1", $ret);
return $ret;
}
