how do i remove underscores from data from a form

hello,

when i receive a form request, the text field name data in the e-mail shows an underscore everywhere a space should be. how do i fix this so that the text field name data is shown without the underscores?

example: this_is_a_sample

thanks

 

$variablename= str_replace("_", " ", $variablename); 

Code (markup):

 

thanks mad4, you rock

 

And if you want to get a little fancier:

$variablename= str_replace("_", " ", $variablename); 
$variablename = ucwords(strtolower($variablename));

Code (markup):

Turns "foo_bar" into "Foo Bar"
