Are there any best practices or specific tutorials available for integrating SQLite with mysqli in PHP?

To integrate SQLite with mysqli in PHP, you can follow best practices by using the SQLite3 class in PHP for SQLite database operations and the mysqli class for MySQL database operations. You can establish separate connections for SQLite and MySQL databases and handle them accordingly in your PHP code.

// SQLite connection
$sqliteConnection = new SQLite3('sqlite_database.db');

// MySQL connection
$mysqliConnection = new mysqli('localhost', 'username', 'password', 'mysql_database');

// Example query for SQLite
$sqliteQuery = "SELECT * FROM table_name";
$sqliteResult = $sqliteConnection->query($sqliteQuery);

// Example query for MySQL
$mysqliQuery = "SELECT * FROM table_name";
$mysqliResult = $mysqliConnection->query($mysqliQuery);

// Handle SQLite result
while ($row = $sqliteResult->fetchArray()) {
    // Process SQLite data
}

// Handle MySQL result
while ($row = $mysqliResult->fetch_assoc()) {
    // Process MySQL data
}

// Close connections
$sqliteConnection->close();
$mysqliConnection->close();
