ARRAYOBJECT.NATCASESORT(3) 1 ARRAYOBJECT.NATCASESORT(3) ArrayObject::natcasesort - Sort an array using a case insensitive "natural order" algorithm SYNOPSIS
public void ArrayObject::natcasesort (void ) DESCRIPTION
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 asso- ciations. This is described as a "natural ordering". PARAMETERS
This function has no parameters. RETURN VALUES
No value is returned. EXAMPLES
Example #1 ArrayObject.natcasesort(3) example <?php $array = array('IMG0.png', 'img12.png', 'img10.png', 'img2.png', 'img1.png', 'IMG3.png'); $arr1 = new ArrayObject($array); $arr2 = clone $arr1; $arr1->asort(); echo "Standard sorting "; print_r($arr1); $arr2->natcasesort(); echo " Natural order sorting (case-insensitive) "; print_r($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 ) For more information see: Martin Pool's Natural Order String Comparison page.
