strip_tags question

[Pobega]

When using strip tags, how would I combine a variable and a string? Where would the comma go exactly? I've tried many things, but nothing seems to work

(I want whatever tags used to be admin controllable, but I ALWAYS want <a> activated since the script needs <a> to work).

do you mean something like

$text = "<a href='nextpage.php'>Test link.</a>";
echo strip_tags($text, '<a>');//allow the <a> tag
