Need some help please

[Vizionz]

I need to replace characters. Now if i launch a url something.php?id=My name Is
it is replaced by %20 something.php?id=My%20name%20Is but for one script i am running on my forum. it is throwing it out as something.php?id=My_name_Is

i need to be able to Take _ and replace with %20 for all urls ?

Can you post the script and I'll fix it.
