NATSORT(3)								 1								NATSORT(3)

natsort - Sort an array using a ";natural order" algorithm

SYNOPSIS
bool natsort (array &$array) DESCRIPTION
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(3)) can be seen in the example below. PARAMETERS
o $array - The input array. RETURN VALUES
Returns TRUE on success or FALSE on failure. CHANGELOG
+--------+---------------------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------------------+ |5.2.10 | | | | | | | Zero padded numeric strings (e.g., '00005') now | | | essentially ignore the 0 padding. | | | | +--------+---------------------------------------------------+ EXAMPLES
Example #1 natsort(3) examples demonstrating basic usage <?php $array1 = $array2 = array("img12.png", "img10.png", "img2.png", "img1.png"); asort($array1); echo "Standard sorting "; print_r($array1); natsort($array2); echo " Natural order sorting "; print_r($array2); ?> 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(3) examples demonstrating potential gotchas <?php echo "Negative numbers "; $negative = array('-5','3','-2','0','-1000','9','1'); print_r($negative); natsort($negative); print_r($negative); echo "Zero padding "; $zeros = array('09', '8', '10', '009', '011', '0'); print_r($zeros); natsort($zeros); print_r($zeros); ?> 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 ) SEE ALSO
