What are the potential pitfalls of using the sort() function in PHP for sorting alphanumeric strings with mixed characters?

When using the sort() function in PHP for sorting alphanumeric strings with mixed characters, the function may not sort the strings as expected. This is because the sort() function treats strings as purely numeric values and may not handle alphanumeric characters correctly. To solve this issue, you can use the natsort() function in PHP, which sorts alphanumeric strings naturally. 

$strings = ["apple", "banana", "100 oranges", "2 apples", "10 bananas"];
natsort($strings);

foreach ($strings as $string) {
    echo $string . "\n";
}
