ArrayObject::natsort — Sort entries using a "natural order" algorithm
Beschreibung
void ArrayObject::natsort ( void )
This method implements a sort algorithm that orders alphanumeric strings in the way a human being would while maintaining key/value associations. This is described as a "natural ordering". An example of the difference between this algorithm and the regular computer string sorting algorithms (used in ArrayObject::asort) method can be seen in the example below.

echo "\nNatural order sorting\n";
print_r($arr2);
