How can PHP be used to create a search function that includes a wildcard character like %?

To create a search function in PHP that includes a wildcard character like %, you can use the SQL LIKE operator in conjunction with the wildcard character %. This allows you to search for partial matches in a database query. By concatenating the wildcard character with the search term before executing the query, you can retrieve results that match the search term with any characters before or after it. 

$search_term = $_GET['search_term'];
$search_query = "SELECT * FROM table_name WHERE column_name LIKE '%" . $search_term . "%'";
// Execute the query and fetch results
