The metadata function

The metadata() function is used to add metadata to a page easily and quickly.

This function must be called on every page.

Metadata are used by applications to preview a webpage with a link, for example, in Discord, if you send, this will appear:

It takes a single argument which is a dictionary of metadata.

// This code will give the same result as the above image.
    "title" => "",
    "description" => " forum is a safe, welcoming and caring place to discover cool stuff, share your knowledge and get help from other users",
    "image" => "/assets/logo.png",
    "large" => false,
    "url" => $_SERVER['REQUEST_URI'],
    "site_name" => "© 2018-" . date('Y') . ", Léopold Koprivnik Ibghy"
  • title: The title of the page.
  • description: The description of the page.
  • image: The icon or banner of the page.
  • url: The URL opened when the user clicks the icon or banner.
  • large: Whether the image will be considered as icon or banner.
  • site_name: The little text that will be shown on the top of the preview

Each key of the dictionary is optional, if it is not set, the default value will be used.

Default values are the same as the code snippet above.

This function also prints other metadata :

<meta name='referrer' content='no-referrer'>
<meta name='theme-color' content='#CE6B82'>
<link rel='icon' type='image/ico' href='/favicon.ico'>
<meta name='viewport' content='width=device-width, initial-scale=1.0'>
<meta charset='UTF-8'>
