str_replace with form help

[MDanz]

With this form... if i typed in "new test" in the search text field the url would come up as

 

test.php?search=new+test

 

How do i get the url to replace spaces as a dash instead of a plus sign?

 

<form action="test.php" method="GET" name="searchbar">

		<?php 


	$search = strtolower($_GET['search']);

	$formpage = $_SERVER['PHP_SELF'];

echo "<input type='text' size='40' name='search' style='font-size:16px; font-family:Arial;font-weight:bold;' />  <input type='submit'  value='Search' style='font-size:14px;' />";

		?>

			</div>

	</form>

a plus sign represents a space character in the url..why do you need to change the character?
