What is the best practice for hiding content on a frontend page based on user input in a form field in PHP?

When hiding content on a frontend page based on user input in a form field in PHP, the best practice is to use JavaScript to dynamically show or hide the content based on the value of the form field. This can be achieved by attaching an event listener to the form field, such as onchange, and then toggling the visibility of the content based on the input value. 

<!DOCTYPE html>
<html>
<head>
  <title>Hide Content based on Form Input</title>
  <script>
    function toggleContent() {
      var inputValue = document.getElementById('inputField').value;
      var content = document.getElementById('contentToHide');

      if (inputValue === 'secret') {
        content.style.display = 'none';
      } else {
        content.style.display = 'block';
      }
    }
  </script>
</head>
<body>

<form>
  <label for="inputField">Enter 'secret' to hide content:</label>
  <input type="text" id="inputField" oninput="toggleContent()">
</form>

<div id="contentToHide">
  <p>This is the content that will be hidden if user inputs 'secret'.</p>
</div>

</body>
</html>
