[Making variable not echo...]

This should be simple -- I am BRAND NEW to PHP...

I have this code...

foreach ($result as $value) {

echo trim($value)."+";


this currently works as it should and let's say the input is hello -- the web output is "hello+helloa+hellob+helloc" as it should be (using the other code in the program before this...  But..  I need to make it the variable so that a variable such as $car = "hello+helloa+hellob+helloc"...

When I simply replace echo trim($value)."+"; with $car = trim($value)."+"; it keeps REPLACING the variable each time and not adding it onto the end.  ANy help would be greatly appreciated.
