Question

I want to match twitter usernames and replace it with a string. This is with PHP

This is the regex I have

/(^|[^a-z0-9_])[@＠]([a-z0-9_]{1,20})([@＠\xC0-\xD6\xD8-\xF6\xF8-\xFF]?)/iu

I have a string like

RT @omglol I am hungry @lolomg bla

I want to replace every username there with a html tag like

<a href="http://lol.com">@omglol</a>

How can I do this? Thaks for answers

Answer 1

$s = "RT @omglol I am hungry @lolomg bla";
$p = "/(@\w+)/";
$r = '<a href="http://lol.com">$1</a>';
print preg_replace($p, $r, $s);

=> RT <a href="http://lol.com">@omglol</a> I am hungry <a href="http://lol.com">@lolomg</a> bla
