How can a PHP beginner troubleshoot and debug issues with reading CSV files into a database table?

When troubleshooting issues with reading CSV files into a database table in PHP, beginners can start by checking the file path, ensuring proper file permissions, and verifying the database connection. They can also use error handling techniques like try-catch blocks and var_dump() to identify any errors in the code or data. 

<?php
// Example PHP code snippet to read a CSV file into a database table

// Database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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

// Read CSV file
$file = fopen("data.csv", "r");

while (($data = fgetcsv($file, 1000, ",")) !== FALSE) {
    $sql = "INSERT INTO table_name (column1, column2, column3) VALUES ('$data[0]', '$data[1]', '$data[2]')";
    
    if ($conn->query($sql) === TRUE) {
        echo "Record inserted successfully";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
}

fclose($file);
$conn->close();
?>
