Here's a PHP function that generates a unique 12-character code following your specified format and checks for uniqueness in a MySQL database: ```php function generateUniqueCode($conn) { do { // Generate code parts $letters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'; // Generate letter sections $letterPart1 = substr(str_shuffle($letters), 0, 3); $letterPart2 = substr(str_shuffle($letters), 0, 3); // Generate number sections with leading zeros $numberPart1 = str_pad(mt_rand(0, 999), 3, '0', STR_PAD_LEFT); $numberPart2 = str_pad(mt_rand(0, 999), 3, '0', STR_PAD_LEFT); // Combine parts $code = $letterPart1 . $numberPart1 . $letterPart2 . $numberPart2; // Check database for existing code $stmt = $conn->prepare("SELECT code FROM codes WHERE code = ?"); $stmt->bind_param("s", $code); $stmt->execute(); $result = $stmt->get_result(); $exists = $result->num_rows > 0; $stmt->close(); } while ($exists); return $code; } ``` **Key features:** 1. Generates code in `LLLNNNLLLNNN` format (3 letters, 3 numbers, 3 letters, 3 numbers) 2. Uses secure random generation with `mt_rand()` and `str_shuffle()` 3. Ensures number sections always have 3 digits with leading zeros 4. Checks for existing codes in the database using prepared statements 5. Guarantees unique code through a loop until a non-existing code is found **Usage:** ```php // Database connection (example using MySQLi) $conn = new mysqli("host", "username", "password", "database"); // Generate unique code $uniqueCode = generateUniqueCode($conn); // Use the generated code echo "Generated Code: " . $uniqueCode; ``` **Required database structure:** ```sql CREATE TABLE codes ( code VARCHAR(12) PRIMARY KEY ); ``` **Notes:** - The code uses MySQLi prepared statements to prevent SQL injection - The loop will continue generating codes until a unique one is found - The function assumes a valid MySQLi connection is passed as a parameter - Character generation uses cryptographically safe methods suitable for most applications - The probability of collision is extremely low (1 in 308 trillion possible combinations)

*You are walking down the streets of loguetown, it's a beautiful day, the sun is shining and the air is warm, you feel a sense of peace and freedom as you walk around, the people are friendly and the town is lively*

Sanji: "What do you mean? I know I'm hot."

*The group bursts out laughing. Brook is on the ground, rolling around and holding his stomach.* Brook: "That's the best comeback I've ever heard!"

*The group goes silent again. Luffy seems a bit disappointed, but then he shrugs it off.* Luffy: "Oh well. Your loss." Sanji: "But you do have to admit, I'm still pretty handsome."

Val: Sanji who lied to you?

*"(start however you want)"*

LUFFY I'm bored.

Luffy: what do you wanna do?
