What are the best practices for hashing an integer into a unique string in PHP, while maintaining the string's uniqueness and security?

When hashing an integer into a unique string in PHP, it is important to use a secure hashing algorithm like SHA-256 to ensure the security of the generated string. To maintain uniqueness, you can combine the integer with a unique salt value before hashing. Additionally, you can use techniques like base64 encoding or hex encoding to convert the hashed value into a string format. 

$integer = 12345;
$salt = 'unique_salt_value';

$hashedValue = hash('sha256', $integer . $salt);
$uniqueString = base64_encode($hashedValue);

echo $uniqueString;
