Change ereg_replace to preg_replace syntax

[halosinfire]

I've never quite understood the syntax of preg_replace and now I need to convert the following line of code from ereg_replace to preg_replace because ereg_replace is deprecated.  Can anyone help?

$qstr = ereg_replace("&page=[0-9]+","",$_SERVER['QUERY_STRING']);

Any help would be greatly appreciated.

For a lot of expressions all you need to do is add delimiters. Most anything will do but / and # are most common.

/&page=[0-9]+/

For eregi methods use the /i flag like /&page=[0-9]+/i.
