ArrayObject::natcasesort — Sort an array using a case insensitive "natural order" algorithm
public ArrayObject::natcasesort ( ) : void
This method is a case insensitive version of ArrayObject::natsort.
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".
This function has no parameters.
No value is returned.
Example #1 ArrayObject::natcasesort() example
<?php$array = array('IMG0.png', 'img12.png', 'img10.png', 'img2.png', 'img1.png', 'IMG3.png');$arr1 = new ArrayObject($array);$arr2 = clone $arr1;$arr1->asort();echo "Standard sorting\n";print_r($arr1);$arr2->natcasesort();echo "\nNatural order sorting (case-insensitive)\n";print_r($arr2);?>
The above example will output:
Standard sorting ArrayObject Object ( [0] => IMG0.png [5] => IMG3.png [4] => img1.png [2] => img10.png [1] => img12.png [3] => img2.png ) Natural order sorting (case-insensitive) ArrayObject Object ( [0] => IMG0.png [4] => img1.png [3] => img2.png [5] => IMG3.png [2] => img10.png [1] => img12.png )
