Need Some PhpHelp Urgent

I am using a script

which replaces "." in the output as "_"

i want "." to stay as it is

Smarty is used in the script

how can i get this problem solved

 

Without seeing the script we can't help.

Base don extreme guesswork, look for str_replace(".", "_"); and delete it.

 

Its A Paid script so im not sure if i can share the source

but here is 1 code i think needs to be changed is it this or some other

  $s = preg_replace('/[^\w]/','_', $s);
  $s = preg_replace(
    array('/[\xf1]/','/[\xe0\xe1]/','/[\xe8\xe9]/','/[\xec\xed]/','/[\xf2\xf3]/','/[\xf9\xfa]/'),
    array('n','a','e','i','o','u'),
    $s );
  $s = urlencode($s);
  $s = preg_replace('/%[A-F0-9]{2}/','_',$s);
  $s = preg_replace('/_{2,}/','_',$s);
  $s = trim($s,'_');
  return $s;

Code (markup):

anything to change in this code

 

I hate Reg Exp so badly I'll pass. It doesn't just replace dots but more. You'll have to add an exception to it somehow (don't know how).

 

oh shits its tough work who is gonna help me solve this
