/// A PHP hashtable.
///
/// In PHP, arrays are represented as hashtables. This allows you to push values
/// onto the end of the array like a vector, while also allowing you to insert
/// at arbitrary string key indexes.
///
/// A PHP hashtable stores values as [`Zval`]s. This allows you to insert
/// different types into the same hashtable. Types must implement [`IntoZval`]
/// to be able to be inserted into the hashtable.
///
/// # Examples
///
/// ```no_run
/// use ext_php_rs::types::ZendHashTable;
///
/// let mut ht = ZendHashTable::new();
/// ht.push(1);
/// ht.push("Hello, world!");
/// ht.insert("Like", "Hashtable");
///
/// assert_eq!(ht.len(), 3);
/// assert_eq!(ht.get_index(0).and_then(|zv| zv.long()), Some(1));
/// ```
