Help with a regular routine?

Question

PHP

I'm bad at them.
In general, text is written to the database, it looks like this there:

Then I display it on the page, having previously processed the links in the form of links and using the nl2br function:

function changeTextToLink($text){
    $text = preg_replace("/(^|[\r\n ])([\w]*?)((www|ftp)\.[^ \,\"\t\n\r<]*[^ \.])/is", "$1$2<a href=\"http://$3\" >$3</a>", $text);
    $text = preg_replace("/(^|[\r\n ])([\w]*?)((ht|f)tp(s)?:\/\/[\w]+[^ \,\"\n\r\t<]*[^ \.])/is", "$1$2<a href=\"$3\" >$3</a>", $text);
    return($text);
}



$text = changeTextToLink($data["text"]);

$nl2 = nl2br($text);

echo $nl2;

Everything would be fine, but it turned out that the links are obtained in the form of:
http://mysite.ru/rules<br />- naturally incorrectly opening
Although the display seems to be normal:

Tell me where you screwed up, and if there is some kind of editing on this matter.
