What are potential pitfalls when using PHP to import CSV files into a MySQL database?

One potential pitfall when using PHP to import CSV files into a MySQL database is not properly handling errors or exceptions during the import process. To solve this issue, you should implement error handling to catch any potential issues that may arise during the import process and handle them appropriately. 

<?php
// 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 CSV file into MySQL database
$csvFile = 'example.csv';
$handle = fopen($csvFile, "r");

if ($handle !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        // Process and insert data into MySQL database
        $sql = "INSERT INTO table_name (column1, column2, column3) VALUES ('" . $data[0] . "', '" . $data[1] . "', '" . $data[2] . "')";

        if ($conn->query($sql) === FALSE) {
            echo "Error: " . $sql . "<br>" . $conn->error;
        }
    }

    fclose($handle);
} else {
    echo "Error opening file";
}

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