How to change the field value depending on the input value?

Question

PHP

Friends, help with advice ..
The essence of the task: to receive incoming data and change to others. For example:
If we get "Select size", then we need to change to "Size".
If we get "Select color", then we need to change it to "Color".
And now in detail. I'm working on a shopping cart in opencart. There, the selected option is attached to the selected product, for example: Select size - 43. The source code is as follows:

<?php foreach ($product['option'] as $option) { ?>
    <?php echo $option['name']; ?>: - <?php echo $option['value']; ?>
<?php } ?>

The value is "Choose Size". And there are many such options. <?php echo $option['name']; ?>

Answer 1

switch ($option['name']) {
    case "Выберите размер":
        echo "Размер";
        break;
    case 1:
        echo "i равно 1";
        break;
    case 2:
        echo "i равно 2";
        break;
    default:
       echo $option['name'];
}

Answer 2

In the most primitive version:

if($_POST['data']==="Выбрать размер") $_POST['data']= "Размер";

Answer 3

In <?php echo $option['name']; ?> is set to "Choose Size".

ok, where should i replace it? what is the principle of replacement? a list in the database, just written out on a piece of paper, an array, is there anything to replace with?
