How to read a post in WordPress PHP

Here’s an example of how you can use get_post() to read a post in WordPress:

$post_id = 1; // the ID of the post you want to read
$post = get_post( $post_id );

// access the post data
$title = $post->post_title;
$content = $post->post_content;
$date = $post->post_date;

// display the post data
echo '<h1>' . $title . '</h1>';
echo '<p>' . $content . '</p>';
echo '<p>' . $date . '</p>';

This code will retrieve the post with the specified ID, and then access the post’s title, content, and date using the post_title, post_content, and post_date properties of the post object. Finally, it will display the post data on the page.

You can also use the WP_Query class to retrieve and display posts in WordPress. This allows you to specify additional parameters, such as the number of posts to retrieve, the order in which the posts should be displayed, and which categories or tags the posts should belong to.

For example, the following code will retrieve and display the most recent 10 posts in WordPress:

$args = array(
    'posts_per_page' => 10, // number of posts to retrieve
    'order' => 'DESC', // show the most recent posts first
);
$query = new WP_Query( $args );

if ( $query->have_posts() ) {
    while ( $query->have_posts() ) {
        $query->the_post();
        // display the post data here
    }
}

This code creates a new WP_Query object and passes in an array of arguments to specify the number of posts to retrieve and the order in which they should be displayed. The have_posts() function is used to check if there are any posts to display, and the the_post() function is used to iterate through the posts and display their data.
