    The get_attachment_icon_src() function in WordPress is used to retrieve the icon URL and the full path to the file associated with a media attachment. It's similar to the wp_get_attachment_image_src() function but specifically for icons. Here's a detailed explanation and sample usage:

    Function:

    get_attachment_icon_src( int $id, bool $fullsize = false ): array

    Description:

    • This function is designed to retrieve the URL of an icon representing a media attachment in WordPress and the full path to the corresponding file on the server.
    • It's particularly useful when you need to display an icon for a media file and know its server path.

    Parameters:

    1. $id (int, optional): The ID of the attachment post. This is the unique identifier for any media item in WordPress.
    2. $fullsize (bool, optional): A boolean value that determines whether to retrieve the full-size image or not. The default value is false.
      • If true, the function returns the full-size icon.
      • If false, it returns a thumbnail-sized icon.

    Return:

    • The function returns an array containing the icon URL and the full path to the file, respectively.
    • If the attachment ID doesn't exist or doesn't have an associated icon, the function may return false or a different response depending on the WordPress version and configurations.

    Sample Usage:

    $attachment_id = 123; // Replace with a valid attachment ID
    $fullsize = true; // Set to true if you want the full-size icon
    
    $icon_details = get_attachment_icon_src($attachment_id, $fullsize);
    
    if ($icon_details) {
        $icon_url = $icon_details[0]; // Icon URL
        $icon_path = $icon_details[1]; // Full path to the file
    
        // Output the icon URL and path
        echo "Icon URL: " . $icon_url . "<br>";
        echo "Icon Path: " . $icon_path;
    } else {
        echo "No icon found for this attachment.";
    }
    

    In this example:

    • Replace 123 with the actual ID of the media attachment.
    • If $fullsize is set to true, the full-size icon details are retrieved; otherwise, the thumbnail-size details are fetched.
    • The function's output includes the URL of the icon and its full path on the server. If no icon is associated with the given ID, a message indicating this is displayed.

    Note:

    • This function is part of WordPress's extensive media handling capabilities and interacts with WordPress's attachment and media functions.
    • Always ensure you're working with valid attachment IDs and consider permissions and security, especially when dealing with file paths.
