Description
bool
natcasesort ( 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".
Returns TRUE on success or FALSE on failure.
natcasesort() is a case insensitive version of
natsort().
Example 1. natcasesort() example
<?php
$array1 = $array2 = array('IMG0.png', 'img12.png', 'img10.png', 'img2.png', 'img1.png', 'IMG3.png');
sort($array1);
echo "Standard sorting\n";
print_r($array1);
natcasesort($array2);
echo "\nNatural order sorting (case-insensitive)\n";
print_r($array2);
?>
|
The above example will output: Standard sorting
Array
(
[0] => IMG0.png
[1] => IMG3.png
[2] => img1.png
[3] => img10.png
[4] => img12.png
[5] => img2.png
)
Natural order sorting (case-insensitive)

(
[0] => IMG0.png
[4] => img1.png
[3] => img2.png
[5] => IMG3.png
[2] => img10.png
