How can inconsistencies between local and server databases impact the functionality of PHP scripts?

Inconsistencies between local and server databases can impact the functionality of PHP scripts by causing data discrepancies and errors. To solve this issue, it is important to ensure that the databases are synchronized and updated regularly to maintain consistency. 

// Connect to local database
$local_host = 'localhost';
$local_username = 'root';
$local_password = '';
$local_dbname = 'local_database';

$local_conn = new mysqli($local_host, $local_username, $local_password, $local_dbname);

// Connect to server database
$server_host = 'server_host';
$server_username = 'server_username';
$server_password = 'server_password';
$server_dbname = 'server_database';

$server_conn = new mysqli($server_host, $server_username, $server_password, $server_dbname);

// Check if connection is successful
if ($local_conn->connect_error || $server_conn->connect_error) {
    die("Connection failed: " . $local_conn->connect_error . $server_conn->connect_error);
}

// Perform data synchronization between local and server databases
// Example: Update server database with data from local database
$query = "UPDATE server_table 
          SET column_name = (SELECT column_name FROM local_table WHERE condition) 
          WHERE condition";

if ($server_conn->query($query) === TRUE) {
    echo "Data synchronized successfully";
} else {
    echo "Error synchronizing data: " . $server_conn->error;
}

// Close database connections
$local_conn->close();
$server_conn->close();
