What potential pitfalls should be considered when using a do-while loop to generate unique keys in PHP?

One potential pitfall when using a do-while loop to generate unique keys in PHP is the possibility of generating duplicate keys if the generation logic is not carefully implemented. To avoid this, you can store generated keys in an array and check if a newly generated key already exists in the array before using it. If a duplicate is found, regenerate the key until a unique one is generated. 

$keys = [];
do {
    $key = generateKey(); // Your key generation logic here
} while (in_array($key, $keys));

$keys[] = $key;
// Use the unique key here
