$angle
)Bu işlev DENEYSELDİR. Bu işlevin davranışı, ismi ve belgeleri PHP'nin sonraki sürümlerinde hiçbir duyuru yapılmaksızın değiştirilebilir. Bu riski göze alamayacaksanız bu işlevi kullanmayın.
swfdisplayitem::rotateto() set the current object
rotation to angle degrees in global coordinates.
The object may be a swfshape(), a swfbutton(), a swftext() or a swfsprite() object. It must have been added using the swfmovie::add().

This example bring three rotating string from the background to the foreground. Pretty nice.

// we can add properties just like a normal PHP var,
// as long as the names aren't already used.
// e.g., we can't set $i->scale, because that's a function
$i = $m->add($t);
$i->x = $x;

$i->rot = $rot;
$i->s = $scale;

// but the changes are local to the function, so we have to
// return the changed object. kinda weird..
