What are the potential pitfalls of using the sort function in PHP for sorting arrays?

One potential pitfall of using the sort function in PHP for sorting arrays is that it only sorts the values of the array and does not maintain the key-value associations. To solve this issue, you can use the asort function instead, which sorts the array by values while keeping the key-value associations intact. 

$array = ['b' => 2, 'a' => 1, 'c' => 3];
asort($array);
print_r($array);
