echo $sa[1];                    // b
unset($sa[1]);
echo $sa;                       // {"0":"a","2":"c"}
$sa[1] = 'Foo';
echo $sa;                       // {"0":"a","2":"c","1":"Foo"}

$b = new xStringBuffer('abc');
$c = new xStringBuffer('a,b,c');

echo $b->length();                  // 3
echo $c->length();                  // 5
foreach($b as $i) echo $i;          // abc
