How can the name attribute of a select field be used to differentiate between different select fields in PHP form processing?

When processing a form with multiple select fields in PHP, the name attribute of each select field can be used to differentiate between them. By giving each select field a unique name attribute, you can access the selected value of each field individually in the PHP form processing code. This allows you to handle each select field separately and perform any necessary actions based on the selected values. 

// HTML form with two select fields
<form method="post" action="process_form.php">
  <select name="select_field1">
    <option value="option1">Option 1</option>
    <option value="option2">Option 2</option>
  </select>
  
  <select name="select_field2">
    <option value="option3">Option 3</option>
    <option value="option4">Option 4</option>
  </select>
  
  <input type="submit" value="Submit">
</form>

// PHP form processing code (process_form.php)
<?php
$select_field1 = $_POST['select_field1'];
$select_field2 = $_POST['select_field2'];

// Process selected values from select_field1 and select_field2
// Perform actions based on the selected values
?>
