php-wordpressHow to get post meta in WordPress using PHP?

Getting post meta in WordPress using PHP is a simple process. You can use the get_post_meta() function to retrieve post meta data.

$post_meta = get_post_meta( $post_id, $key, $single );

The get_post_meta() function takes three parameters:

• $post_id: The ID of the post to retrieve meta data from.
• $key: The meta key to retrieve.
• $single: Whether to return a single value or an array.

The output of the get_post_meta() function is an array of post meta data.

(
    [0] => post_meta_value
)
