Can you explain the importance of error handling and transparency in PHP scripts that interact with databases for maintaining data integrity and user experience?

Error handling is crucial in PHP scripts that interact with databases to maintain data integrity and provide a good user experience. Proper error handling ensures that any issues with database queries or connections are caught and dealt with appropriately, preventing data corruption or loss. Transparency in error messages also helps users understand what went wrong and how to resolve the issue, improving the overall user experience. 

// Set up error handling for database interactions
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
try {
    $connection = new mysqli('localhost', 'username', 'password', 'database');
} catch (mysqli_sql_exception $e) {
    // Handle database connection errors
    echo 'Database connection error: ' . $e->getMessage();
    exit;
}

// Perform database queries
$query = "SELECT * FROM users";
$result = $connection->query($query);
if (!$result) {
    // Handle query execution errors
    echo 'Query execution error: ' . $connection->error;
    exit;
}

// Process query results
while ($row = $result->fetch_assoc()) {
    // Do something with the data
}

// Close database connection
$connection->close();
