natsort Sort an array using a "natural order" algorithm boolnatsort arrayarray This function 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 sort) can be seen below: &return.success; ]]> &example.outputs; img1.png [1] => img10.png [2] => img12.png [3] => img2.png ) Natural order sorting Array ( [3] => img1.png [2] => img2.png [1] => img10.png [0] => img12.png ) ]]> For more information see: Martin Pool's Natural Order String Comparison page.
