What is the difference between standard sorting and natural sorting in PHP when sorting arrays?

Standard sorting in PHP uses algorithms like quicksort or mergesort to sort arrays based on numerical or alphabetical order. Natural sorting, on the other hand, sorts arrays in a way that is more human-friendly, taking into account numbers within strings and sorting them in a way that makes sense to humans (e.g., 'file1.txt' comes before 'file2.txt'). To perform natural sorting in PHP, you can use the `natsort()` function. 

// Standard sorting
$numbers = array(1, 5, 3, 2, 4);
sort($numbers);
print_r($numbers); // Output: Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 )

// Natural sorting
$files = array("file2.txt", "file10.txt", "file1.txt");
natsort($files);
print_r($files); // Output: Array ( [2] => file1.txt [0] => file2.txt [1] => file10.txt )
