How can the sum be calculated with both texts and numbers in a PHP form?

To calculate the sum of both text and numbers in a PHP form, you can use the `$_POST` superglobal to retrieve the values entered by the user in the form fields. You can then convert the text input to a number using `intval()` or `floatval()` functions before adding them together to get the sum. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $textValue = $_POST['text_input'];
    $numberValue = $_POST['number_input'];
    
    $textValueAsNumber = floatval($textValue);
    $sum = $textValueAsNumber + $numberValue;
    
    echo "The sum of the text and number is: " . $sum;
}
?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    Text Input: <input type="text" name="text_input"><br>
    Number Input: <input type="number" name="number_input"><br>
    <input type="submit" value="Calculate Sum">
</form>
