$array =3D preg_split('/\W+/',$string,-1,PREG_SPLIT_NO_EMPTY);

"A "word" character is any letter or digit or the underscore character, =

that is, any character which can be part of a Perl "word". The definitio=
n =
of letters and digits is controlled by PCRE's character tables, and may =

vary if locale-specific matching is taking place. For example, in the "f=
r" =
(French) locale, some character codes greater than 128 are used for =
accented letters, and these are matched by \w."
