What are the best practices for assigning fixed IDs in PHP when working with MySQL databases?

When working with MySQL databases in PHP, it is important to assign fixed IDs to ensure consistency and avoid conflicts. One common practice is to use auto-increment primary keys in MySQL tables to automatically generate unique IDs for each record. Another approach is to manually assign fixed IDs based on a specific pattern or algorithm to maintain control over the ID values. 

// Using auto-increment primary key in MySQL table
$query = "CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(50)
)";

// Manually assigning fixed IDs based on a specific pattern
$id = 1001; // Starting ID value
$query = "INSERT INTO products (id, name) VALUES ('$id', 'Product A')";
$id++; // Increment ID value for the next record
$query = "INSERT INTO products (id, name) VALUES ('$id', 'Product B')";
