[RESOLVED] variable value question

[kpowning]

I have the following variable:

$test = "9400 1159 0104 8662 0769 40";

How can I add a (+) symbol between all the spaces in the value for $test?
It should end up like this: "9400+1159+0104+8662+0769+40"

I appreciate any help on this...

I used str_replace(" ", "+", $string);
sorry for this post...
