PHP: Adjust regex to add a character at the end of every word

I have following regex:

// Before: "Foo Bar Test";
$str = preg_replace( "/(^| )(\w)/", '$1+$2', $str );
// After: "+Foo +Bar +Test";

Is it possible to add the char "*" at the end of every word?

The result I am looking for is:

// +Foo* +Bar* +Test*

Is it possible to do it in the same regex? Or do I have to use a new one?

You can do:

$str = preg_replace( "/(^| )(\w+)\b/", '$1+$2*', $str );

echo "$str\n";
//=> +Foo* +Bar* +Test*

Making 2nd captured group as (\w+) will make it capture full word and putting * after $2 will place * at right place.

PS: You can also use lookbehind assertion:

$str = preg_replace( "/(?<= |^)(\w+)\b/", '+$1*', $str );

to get the same output.
