Yes, it is possible to modify the code to use the same table but different data values from the form. Here are the steps to modify the code:

1. Remove the existing table display code inside the if statement that checks the value of $plan.
2. Add a new variable $table_data as an empty array before the if statement that checks the value of $plan.
3. Inside the if statement that checks the value of $plan, use the $table_data array to store the data for the table based on the selected age, sex, and plan.
4. Use a loop to iterate through the $table_data array and display the table data.

To use the same table but different data values, you can modify the code as follows:

// Display a table for each plan
if ($plan == 1 || $plan == 2 || $plan == 3 || $plan == 4) {
    echo "<table>";
    foreach ($value_pairs[$plan] as $age => $values) {
        if ($plan == 1) {
            $age_label = $age1;
            $male_value = $values['male1'];
            $female_value = $values['female1'];
        } elseif ($plan == 2) {
            $age_label = $age2;
            $male_value = $values['male2'];
            $female_value = $values['female2'];
        } elseif ($plan == 3) {
            $age_label = $age3;
            $male_value = $values['male3'];
            $female_value = $values['female3'];
        } elseif ($plan == 4) {
            $age_label = $age4;
            $male_value = $values['male4'];
            $female_value = $values['female4'];
        }
        echo "<tr><td>Age: ".$age_label."</td><td>Male Value: ".$male_value."</td><td>Female Value: ".$female_value."</td></tr>";
    }
    echo "</table>";
} else {
    echo "Invalid plan selected.";
}

we can use a single table for all plans and just update the column headings based on the selected plan. Here’s an example of how to modify the code:

// Display a table for each plan
if ($plan >= 1 && $plan <= 4) {
    echo '<table>';
    foreach ($value_pairs[$plan] as $age => $values) {
        $male_col = 'male' . $plan;
        $female_col = 'female' . $plan;
        echo "<tr><td>Age: $age</td><td>Male Value: $values[$male_col]</td><td>Female Value: $values[$female_col]</td></tr>";
    }
    echo '</table>';
} else {
    echo 'Invalid plan selected.';
}

This code checks if the selected plan is between 1 and 4 (inclusive), and then loops through the data to display a table with the appropriate column headings based on the selected plan. We can use string concatenation to dynamically build the column names based on the selected plan number.
