1. Regular Expression Route:
preg_match_all('/([^!=3D]+)=3D([^!=3D]+)!/',$cookiestring,$matches,PREG_=
PATTERN_ORDER);
$r =3D array_combine($matches[1],$matches[2]);
2. Exploding Route:
$values =3D explode('!',$cookiestring);
array_walk($values,create_function('$v,$k,&$array','list($key,$value) =3D=
=
explode(\'=3D\',$v);$array[$key] =3D [$values];));
Both untested, so there may be some typing errors.
