Question

I’m trying to use this line of code to accept URL variables with spaces replaced by ‘%20’ but it also has to go through a regex

$type=urldecode(ereg_replace("[^a-zA-Z0-9%]+", "", @$_REQUEST['type']));

The result is just the %20 removed instead of replacing with a space e.g JohnDoe not John Doe, from John%20Doe

Answer 1

You have the order wrong and note that ereg_replace is depreciated .. preg_replace is a better option

Try

 $type  = ereg_replace("[^a-zA-Z0-9%]+", "", urldecode(@$_REQUEST['type']));

Better Approch

$type = @$_REQUEST['type'] ; 
$type = urldecode($type);
$type = str_replace(" ","",$type) ;

Thanks
