natsortSort an array using a "natural order" algorithm Description
true natsort(array
&$array )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".

Example #1 natsort examples demonstrating basic usage
The above example will output: Standard sorting Array ( [3] => img1.png [1] => img10.png [0] => img12.png [2] => 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. Example #2 natsort examples demonstrating potential gotchas
The above example will output: Negative numbers Array ( [0] => -5 [1] => 3 [2] => -2 [3] => 0 [4] => -1000 [5] => 9 [6] => 1 ) Array ( [2] => -2 [0] => -5 [4] => -1000 [3] => 0 [6] => 1 [1] => 3 [5] => 9 ) Zero padding Array ( [0] => 09 [1] => 8 [2] => 10 [3] => 009 [4] => 011 [5] => 0 ) Array ( [5] => 0 [1] => 8 [3] => 009 [0] => 09 [2] => 10 [4] => 011 ) |
