What are the potential pitfalls of not matching the number of variables with the number of parameters in a prepared statement in PHP?

If the number of variables does not match the number of parameters in a prepared statement in PHP, it can lead to errors such as SQL syntax errors or unexpected behavior. To solve this issue, make sure that the number of variables passed to the `bind_param()` method matches the number of placeholders in the SQL query. 

// Correcting the number of variables to match the number of parameters in the prepared statement
$stmt = $mysqli->prepare("INSERT INTO table_name (column1, column2) VALUES (?, ?)");
$stmt->bind_param("ss", $variable1, $variable2);
$stmt->execute();
