Error: Strict Standards:

Hi, i get this error:
Strict Standards: Only variables should be passed by reference in C:\www\sgo\manager\lib\string_delimiter.class.php on line 27

26 $pedacosStringOriginal = explode(" ", $string);
27 $tamUltimaPalavraCortada = strlen(end(explode(" ", $novaString)));

fix after change the code like this:

26 $pedacosStringOriginal = explode(" ", $string);
27 $arr = explode(" ", $novaString);
28 $tamUltimaPalavraCortada = strlen(end($arr));
