Sure, here is how to fetch the value of the selected options in a dropdown in PHP:

PHP

// Get the value of the selected option
$selected_option = $_POST['select_list_name'];

// Check if the selected option is not empty
if (!empty($selected_option)) {
  // Get the value of the selected option
  $selected_option_value = $selected_option['value'];
} else {
  // The selected option is empty
  $selected_option_value = '';
}

The $_POST['select_list_name'] variable will contain the name of the dropdown list. The selected_option variable will contain an array of objects, where each object represents a selected option. The value property of each object will contain the value of the selected option.

If the selected_option variable is empty, then the user has not selected any option from the dropdown list. In this case, the selected_option_value variable will be set to an empty string.

Here is an example of how to use this code:

PHP

<html>
<body>

<form action="index.php" method="post">
  <select name="select_list_name">
    <option value="1">Option 1</option>
    <option value="2">Option 2</option>
    <option value="3">Option 3</option>
  </select>
  <input type="submit" value="Submit">
</form>

<?php
// Get the value of the selected option
$selected_option = $_POST['select_list_name'];

// Check if the selected option is not empty
if (!empty($selected_option)) {
  // Get the value of the selected option
  $selected_option_value = $selected_option['value'];
  echo "The selected option value is: $selected_option_value";
} else {
  // The selected option is empty
  echo "No option selected";
}
?>

</body>
</html>

This code will create a dropdown list with three options. When the user submits the form, the value of the selected option will be displayed.
