using preg_replace in php to remove space in php

Question

I have the following String + Example + Test + Test2 and using preg_replace I would like to get the following result +Example +Test +Test2

I have been trying to use the following code

preg_replace("/\s*([\+])\s*/", "$1", $string)

but this one is returning

+Example+Test+Test2

$output = str_replace('+ ', '+', $input);

or

$output = preg_replace('/\\+\\s+/', '+', $input);

What about multiple spaces before the +? I know the Q doesn't say it (but it implies it). Just being mischievous :)

$output = trim(preg_replace('/\s*+\s*/', ' +', $input));
