What are the potential drawbacks of reading data directly from a CSV file instead of using MySQL?

One potential drawback of reading data directly from a CSV file instead of using MySQL is that CSV files may not be as efficient for handling large datasets or complex queries compared to a database management system like MySQL. Additionally, CSV files do not support advanced features such as indexing, transactions, or data integrity constraints that are commonly used in MySQL databases. To address this issue, consider importing the data from the CSV file into a MySQL database for better performance and scalability. 

// Connect to MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Import data from CSV file into MySQL table
$csvFile = 'data.csv';
$tableName = 'my_table';

$sql = "LOAD DATA INFILE '$csvFile' INTO TABLE $tableName FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n' IGNORE 1 LINES";

if ($conn->query($sql) === TRUE) {
    echo "Data imported successfully";
} else {
    echo "Error importing data: " . $conn->error;
}

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