How can one properly handle column count mismatches in SQL queries in PHP?

When handling column count mismatches in SQL queries in PHP, one solution is to use the `rowCount()` method to check the number of columns returned by the query result before attempting to fetch the data. This way, you can avoid errors caused by inconsistent column counts in the result set. 

// Execute the SQL query
$stmt = $pdo->query("SELECT column1, column2 FROM table");

// Check if the number of columns in the result set matches the expected count
if ($stmt->columnCount() == 2) {
    // Fetch the data from the result set
    while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
        // Process the data
        echo $row['column1'] . ' ' . $row['column2'] . '<br>';
    }
} else {
    // Handle the column count mismatch error
    echo "Error: Column count mismatch in SQL query result";
}
