What is the significance of using LOAD DATA LOCAL INFILE in PHP for importing CSV files into a database?

Using LOAD DATA LOCAL INFILE in PHP allows for efficient importing of CSV files into a database by directly loading the data from the file into the database table. This method is faster and more resource-efficient compared to manually parsing and inserting each row of data. However, it is important to note that using this method may pose security risks if not handled properly. 

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

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

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

$sql = "LOAD DATA LOCAL INFILE 'path/to/file.csv' 
        INTO TABLE table_name 
        FIELDS TERMINATED BY ',' 
        LINES TERMINATED BY '\n' 
        IGNORE 1 LINES";

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

$conn->close();
?>
