HTML/PHP - Form - Input as array

To create an HTML form that submits an array as a form parameter, you can use the name attribute of the input element and give it a value in the form of an array.

For example:

<form method="POST">
  <input type="text" name="colors[]" value="red">
  <input type="text" name="colors[]" value="green">
  <input type="text" name="colors[]" value="blue">
  <input type="submit" value="Submit">
</form>

This will create an HTML form that submits an array called colors when the form is submitted. The values of the colors array will be the values of the input elements in the form.

In PHP, you can access the colors array like this:

$colors = $_POST['colors'];

This will assign the colors array to the $colors variable. You can then loop through the array and access the individual values like this:

<?php

foreach ($colors as $color) {
  echo $color;
}

This will output the values of the colors array (i.e., "red", "green", and "blue") one at a time.
