Check out the ereg_replace in the manual.
Here's what it looks like using a preg.
But, you'll have to change those double quotes in the $str
assignment to single quotes. Well, only way I could get it to
work. Anyone? It's that '$' for the var that causes probs.
$pat = '/<:\$(\w+):>/';
$replace = '\\1';
$new_str = preg_replace($pat, $replace, $str);
$print $new_str;
?>
</HTML>
It should work on your example string. No guarantee on other
input.
