Get URL of Featured Image After wp_insert_post()

Question

I want to get the url of a featured image.

I've created a function with wp_insert_post to post data and set a featured image for them. Everything works fine except displaying the url of featured image.

Here is my code :

$newpostname = $movie['title'];

global $wpdb;

$id_ofpost_name     = $wpdb->get_var( "SELECT ID FROM $wpdb->posts WHERE post_name = '$newpostname'" );
$id_ofpost_title    = $wpdb->get_var( "SELECT ID FROM $wpdb->posts WHERE post_title = '$newpostname'" );

if( $id_ofpost_name || $id_ofpost_title ) { echo 'post Exist'; } 
else {
    // Register Post Data
    $post                   = array();
    $post['post_status']    = 'publish';
    $post['post_type']      = 'post';               // can be a CPT too
    $post['post_title']     = $newpostname;
    $post['post_content']   = '';
    $post['post_author']    = 1;

    // Create Post
    $post_id = wp_insert_post( $post );

    // Add Featured Image to Post
    $image_url  = $movie['urlPoster'];
    $upload_dir = wp_upload_dir();                  // Set upload folder
    $image_data = file_get_contents( $image_url );  // Get image data
    $filename   = basename( $image_url );           // Create image file name

    // Check folder permission and define file location
    if( wp_mkdir_p( $upload_dir['path'] ) ) {
        $file = $upload_dir['path'] . '/' . $filename;
    } else {
        $file = $upload_dir['basedir'] . '/' . $filename;
    }

    // Create the image  file on the server
    file_put_contents( $file, $image_data );

    // Check image file type
    $wp_filetype = wp_check_filetype( $filename, null );

    // Set attachment data
    $attachment = array(
        'post_mime_type' => $wp_filetype['type'],
        'post_title'     => sanitize_file_name( $filename ),
        'post_content'   => '',
        'post_status'    => 'inherit'
    );

    // Create the attachment
    $attach_id = wp_insert_attachment( $attachment, $file, $post_id );

    // Include image.php
    require_once(ABSPATH . 'wp-admin/includes/image.php');

    // Define attachment metadata
    $attach_data = wp_generate_attachment_metadata( $attach_id, $file );

    // Assign metadata to attachment
    wp_update_attachment_metadata( $attach_id, $attach_data );

    // And finally assign featured image to post
    set_post_thumbnail( $post_id, $attach_id );
}

The post inserting works perfectly! The problem is that I want to get the url of featured image after upload. How can I do that?

Well you have the ID as $attach_id so you can use a function such as wp_get_attachment_url() where you can pass $attach_id and get a url returned:

$featured_url = wp_get_attachment_url( $attach_id );

Or if you want more information such as width, height, etc. you can use functions like wp_get_attachment_image_src() or wp_get_attachment_metadata().
