How can PHP beginners learn to create a search feature for their website?

PHP beginners can learn to create a search feature for their website by utilizing PHP's built-in functions for handling form submissions and querying a database. They can start by creating a search form on their website where users can input keywords. Then, they can use PHP to process the form submission, sanitize the input, and construct a SQL query to search for relevant results in the database. Finally, they can display the search results on their website in a user-friendly format. 

<?php
// Check if the search form is submitted
if(isset($_POST['search'])) {
    // Sanitize the search query
    $search_query = htmlspecialchars($_POST['search']);
    
    // Connect to the database
    $conn = new mysqli('localhost', 'username', 'password', 'database_name');
    
    // Construct the SQL query
    $sql = "SELECT * FROM table_name WHERE column_name LIKE '%$search_query%'";
    
    // Execute the query
    $result = $conn->query($sql);
    
    // Display the search results
    while($row = $result->fetch_assoc()) {
        echo $row['column_name'];
    }
    
    // Close the database connection
    $conn->close();
}
?>
