What is the potential issue with sorting an associative array in PHP?

When sorting an associative array in PHP using functions like `ksort()` or `asort()`, the keys and values get rearranged based on the sorting criteria. This can lead to a mismatch between keys and values if they are not properly re-associated after sorting. To solve this issue, you can use `uksort()` or `uasort()` functions with a custom comparison function that maintains the key-value association during sorting. 

$assocArray = ['b' => 2, 'a' => 1, 'c' => 3];

uksort($assocArray, function($a, $b) {
    return $a <=> $b;
});

print_r($assocArray);
