What potential issue is the user facing with the sorting of the array in PHP?

The potential issue the user is facing with sorting the array in PHP is that the `sort()` function in PHP re-indexes the array numerically starting from 0 after sorting it. If the user wants to maintain the original keys of the array after sorting, they can use the `asort()` function instead, which sorts the array by values while maintaining the key-value associations. 

// Original array with keys
$array = array("b" => 2, "a" => 1, "c" => 3);

// Sort the array by values while maintaining keys
asort($array);

// Output the sorted array
print_r($array);
