How can special characters in search queries be properly handled in PHP forms without using urlencode and urldecode?

Special characters in search queries can be properly handled in PHP forms by using the htmlspecialchars function to encode the special characters before displaying them in the form, and then using the htmlspecialchars_decode function to decode the special characters before processing the search query. This approach helps prevent any potential security vulnerabilities and ensures that the special characters are handled correctly in the form. 

$search_query = isset($_POST['search_query']) ? htmlspecialchars($_POST['search_query']) : '';

// Display the search form with encoded special characters
echo '<form method="post" action="search.php">';
echo '<input type="text" name="search_query" value="' . $search_query . '">';
echo '<input type="submit" value="Search">';
echo '</form>';

// Decode the special characters before processing the search query
$decoded_search_query = htmlspecialchars_decode($search_query);

// Process the search query
// Example: perform search using $decoded_search_query
