Document super globals

[kakserpom]

Description

Is there an idiomatic way to access superglobals?

I needed to access $_COOKIE and I've resorted to

let cookie = Function::try_from_function("filter_input")
    .ok_or_else(|| anyhow!("filter_input is not available"))?
    .try_call(vec![&INPUT_COOKIE, &self.cookie_name, &FILTER_DEFAULT])
    .map_err(|err| anyhow!("Could not call filter_input: {}", err))?
    .string();

It would be nice to access PHP constants, too. For now I am just defining them in Rust.

Additional Context

• I can try implementing this feature myself (please assign me to this issue)

Did you try

ext-php-rs/src/zend/globals.rs

Lines 424 to 434 in 1de4bee

	/// Get the HTTP Cookie variables. Equivalent of $_COOKIE.
	///
	/// # Panics
	///
	/// * If the cookie global is not found or fails to be populated.
	#[must_use]
	pub fn http_cookie_vars(&self) -> &ZendHashTable {
	self.http_globals[TRACK_VARS_COOKIE as usize]
	.array()
	.expect("Type is not a ZendArray")
	}

Yeah, my bad, this works:

 let cookie = ProcessGlobals::get()
      .http_cookie_vars()
      .get(self.cookie_name.as_str())
      .and_then(Zval::string);

I didn't look further than https://davidcole1340.github.io/ext-php-rs

So it's a doc issue.
