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
)
