How can dynamic data insertion into a database table be achieved in PHP when the number of values is not known beforehand?

When the number of values to be inserted into a database table is not known beforehand, we can use PHP arrays to dynamically generate the values and then insert them into the table using a prepared statement with placeholders. This allows for flexible insertion of data without knowing the exact number of values in advance. 

// Assume $values is an array containing the values to be inserted
// Assume $conn is the database connection object

// Generate placeholders for the values
$placeholders = implode(',', array_fill(0, count($values), '?'));

// Prepare the SQL statement with placeholders
$sql = "INSERT INTO table_name (column1, column2, ...) VALUES ($placeholders)";
$stmt = $conn->prepare($sql);

// Bind the values to the placeholders and execute the statement
$stmt->execute($values);
