HH\Map::getIterator
Returns an iterator that points to beginning of the current Map
public function getIterator(): KeyedIterator<Tk, Tv>;
Returns
KeyedIterator<Tk,Tv>- AKeyedIteratorthat allows you to traverse the currentMap.
Examples
This example shows how to get a KeyedIterator from a Map and how to consume it:
$m = Map {
'red' => '#ff0000',
'green' => '#00ff00',
'blue' => '#0000ff',
'yellow' => '#ffff00',
};
// Get an iterator for the Map of colors to hex codes
$iterator = $m->getIterator();
// Print each color (key) and hex code (value) using the iterator
while ($iterator->valid()) {
echo $iterator->key().' => '.$iterator->current()."\n";
$iterator->next();
}
