What is the difference between sort() and natcasesort() in PHP when sorting arrays?

The main difference between sort() and natcasesort() in PHP when sorting arrays is that sort() sorts the array in a case-sensitive manner, while natcasesort() sorts the array in a case-insensitive manner. This means that sort() will consider uppercase and lowercase letters as different when sorting, while natcasesort() will treat them as the same.

// Using sort() to sort an array in a case-sensitive manner
$array = ["apple", "Orange", "banana"];
sort($array);
print_r($array);

// Using natcasesort() to sort an array in a case-insensitive manner
$array = ["apple", "Orange", "banana"];
natcasesort($array);
print_r($array);
