How can PHP beginners effectively fill their own WordPress content without using xmlrpc or plugins?

PHP beginners can effectively fill their own WordPress content by using the built-in WordPress functions like wp_insert_post(). This function allows users to programmatically create new posts with specified content, title, and other parameters. By utilizing this function, beginners can easily add new content to their WordPress site without the need for xmlrpc or additional plugins.

// Create a new post
$new_post = array(
    'post_title' => 'New Post Title',
    'post_content' => 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.',
    'post_status' => 'publish',
    'post_author' => 1
);

// Insert the post into the database
$post_id = wp_insert_post($new_post);

if ($post_id) {
    echo "Post created successfully with ID: " . $post_id;
} else {
    echo "Error creating post";
}
