Natsort example

Shows the advantages of natsort() in comparison to sort().

// create a example array
$array_1 = array(
    'pic10.jpg', 'pic3.jpg', 'pic1.jpg',
    'pic7.jpg', 'pic99.jpg', 'pic127.jpg'
);

// copy array 1
$array_2 = $array_1;


sort($array_1);

print "Standard sorting algorithm:<br/>\n";
print_r($array_1);
print "\n\n";


natsort($array_2);

print "Natural order sorting:<br/>\n";
print_r($array_2);

/*
Output:

Standard sorting algorithm

    [0] => pic1.jpg
    [1] => pic10.jpg
    [2] => pic127.jpg
    [3] => pic3.jpg
    [4] => pic7.jpg
    [5] => pic99.jpg
)


Natural order sorting
