$wpdb->get_results() in WordPress: How to Retrieve Multiple Rows from a Database Table

$wpdb->get_results() is a method in WordPress that is used to retrieve multiple rows from a database table. It returns an array of objects or arrays representing the rows fetched from the database.\n\nHere is an example of using $wpdb->get_results():\n\nphp\nglobal \$wpdb;\n\n// Retrieve all rows from the 'wp_posts' table\n\$results = \$wpdb->get_results( "SELECT * FROM wp_posts" );\n\n// Loop through the results and display the post titles\nforeach ( \$results as \$post ) {\n echo \$post->post_title . "<br>";\n}\n\n\nIn this example, we are using $wpdb->get_results to fetch all rows from the 'wp_posts' table in the WordPress database. We then loop through the results and display the post titles for each row fetched.
