Creating php files with php?

[bobbobbobbob]

Hey

I want to create a php file in one of my directories with content on it is changed when a user enters certain information through a form. Any idea how do do this?

Ah, and one more question.

echo"<INPUT TYPE=\"submit\" name=\"sub".$id."\" value=\"Change\">"; 

I have this in a while loop that creates a button to present the option to change all of the things that are shown. How would I run the check to see if they clicked with the variable in teh name?

I have

if(isset($_POST["sub".$id.""])){ 

but it isn't working out.

Thanks

if(isset($_POST[$keyname])){
//..
?>
