How can the issue of automatically redirecting to the search page before displaying the results page be resolved in PHP?

Issue: The problem of automatically redirecting to the search page before displaying the results page can be resolved by checking if the search form has been submitted. If it has, then the results should be displayed; otherwise, the search form should be shown. 

<?php
if(isset($_POST['search'])) {
    // Process search query and display results
    echo "Search results will be displayed here.";
} else {
    // Show search form
    echo "<form method='post'><input type='text' name='search'><input type='submit' value='Search'></form>";
}
?>
