How can errors be effectively debugged when trying to save multiple values from an array to a database in PHP?

When saving multiple values from an array to a database in PHP, errors can be effectively debugged by checking for any syntax errors in the SQL query, ensuring that the database connection is established correctly, and validating the data being inserted into the database. Additionally, using error handling techniques such as try-catch blocks can help in identifying and resolving any issues that may arise during the data insertion process.

// Assuming $values is an array containing the values to be saved to the database

// Establish a database connection
$connection = new mysqli('localhost', 'username', 'password', 'database');

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

// Prepare and execute the SQL query to insert values from the array into the database
foreach ($values as $value) {
    $sql = "INSERT INTO table_name (column_name) VALUES ('$value')";
    
    if ($connection->query($sql) === TRUE) {
        echo "Record inserted successfully";
    } else {
        echo "Error: " . $sql . "<br>" . $connection->error;
    }
}

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