	/**
	 * Attempts to convert a URL into embed HTML.
	 *
	 * In non-raw mode, starts by checking the URL against the regex of the registered embed handlers.
	 * If none of the regex matches and it's enabled, then the URL will be given to the WP_oEmbed class.
	 *
	 * In raw mode, checks the providers directly and returns the data.
	 *
	 * ## OPTIONS
	 *
	 * <url>
	 * : URL to retrieve oEmbed data for.
	 *
	 * [--width=<width>]
	 * : Width of the embed in pixels.
	 *
	 * [--height=<height>]
	 * : Height of the embed in pixels.
	 *
	 * [--post-id=<id>]
	 * : Cache oEmbed response for a given post.
	 *
	 * [--discover]
	 * : Enable oEmbed discovery. Defaults to true.
	 *
	 * [--skip-cache]
	 * : Ignore already cached oEmbed responses. Has no effect if using the 'raw' option, which doesn't use the cache.
	 *
	 * [--skip-sanitization]
	 * : Remove the filter that WordPress from 4.4 onwards uses to sanitize oEmbed responses. Has no effect if using the 'raw' option, which by-passes sanitization.
	 *
	 * [--do-shortcode]
	 * : If the URL is handled by a registered embed handler and returns a shortcode, do shortcode and return result. Has no effect if using the 'raw' option, which by-passes handlers.
	 *
	 * [--limit-response-size=<size>]
	 * : Limit the size of the resulting HTML when using discovery. Default 150 KB (the standard WordPress limit). Not compatible with 'no-discover'.
	 *
	 * [--raw]
	 * : Return the raw oEmbed response instead of the resulting HTML. Ignores the cache and does not sanitize responses or use registered embed handlers.
	 *
	 * [--raw-format=<json|xml>]
	 * : Render raw oEmbed data in a particular format. Defaults to json. Can only be specified in conjunction with the 'raw' option.
	 * ---
	 * options:
	 *   - json
	 *   - xml
	 * ---
	 *
	 * ## EXAMPLES
	 *
	 *     # Get embed HTML for a given URL.
	 *     $ wp embed fetch https://www.youtube.com/watch?v=dQw4w9WgXcQ
	 *     <iframe width="525" height="295" src="https://www.youtube.com/embed/dQw4w9WgXcQ?feature=oembed" ...
	 *
	 *     # Get raw oEmbed data for a given URL.
	 *     $ wp embed fetch https://www.youtube.com/watch?v=dQw4w9WgXcQ --raw
	 *     {"author_url":"https:\/\/www.youtube.com\/user\/RickAstleyVEVO","width":525,"version":"1.0", ...
