& issue in link

[TheAdminMarket]

Hello,

All suddently, something that was working on other cases, does not works now. I've in my code:

PHP Code:

$title = '[URL='.$site_url.'/pms.php?do=index&pmid='.$pmid.']'.htmlspecialchars_uni($pm["title"]).'[/URL]'; 


When user clicks it (in PM) the actual link in the broser becomes:

www.domain.com/pms.php?do=index&&pmid=2

If I change it to:

PHP Code:

$title = '[URL='.$site_url.'/pms.php?do=index&pmid='.$pmid.']'.htmlspecialchars_uni($pm["title"]).'[/URL]'; 


the url in the browser is:

www.domain.com/pms.php?do=index&pmid=2

but still does not works unless if I manually change in the browser & to &

Any ideas?

Thank you
