         * ## Example Usage
         * 1. **Local Connection:**
         * 
         *    Establishing a connection to a local database is straightforward with LibSQL. You have three options:
         * 
         *    a. **Standard DSN Connection:** If you're using a DSN string, use the following format:
         *       ```
         *       $db = new LibSQL("libsql:dbname=database.db", LibSQL::OPEN_READWRITE | LibSQL::OPEN_CREATE, "");
         *       ```
         *       
         *    b. **Standard SQLite Connection:** For direct SQLite connections, simply provide the database file name:
         *       ```
         *       $db = new LibSQL("database.db", LibSQL::OPEN_READWRITE | LibSQL::OPEN_CREATE, "");
         *       ```
         *       
         *    c. **Standard LibSQL Connection:** Alternatively, you can specify the file protocol explicitly:
         *       ```
         *       $db = new LibSQL("file:database.db", LibSQL::OPEN_READWRITE | LibSQL::OPEN_CREATE, "");
         *       ```
         * 
         * 2. **Remote Connection:**
         * 
         *    Connecting to a remote database is equally effortless. Choose between two options:
         * 
         *    a. **Standard DSN Connection with 'libsql://':**
         *       ```
         *       $db = new LibSQL("libsql:dbname=libsql://database-org.turso.io;authToken=random-token");
         *       ```
         *       
         *    b. **Standard DSN Connection with 'https://':**
         *       ```
         *       $db = new LibSQL("libsql:dbname=https://database-org.turso.io;authToken=random-token");
         *       ```
         * 
         * 3. **Remote Replica Connection:**
         * 
         *    To set up a replica connection for distributed systems, follow these steps:
         * 
         *    a. Define the configuration array with the required parameters:
         *       ```
         *       $config = [
         *          "url" => "file:database.db",
         *          "authToken" => "secrettoken",
         *          "syncUrl" => "libsql://database-org.turso.io",
         *          "syncInterval" => 5,
         *          "read_your_writes" => true,
         *          "encryptionKey" => "",
         *       ];
         *       ```
         * 
         *    b. Instantiate a new LibSQL object with the configuration array:
         *       ```
         *       $db = new LibSQL($config);
         *       ```
         * 
         * With this Quick Start guide, you're ready to seamlessly integrate LibSQL PHP Extension into your projects, whether for local, remote, or distributed database connections.
