HH\Vector::get
Returns the value at the specified key in the current Vector
public function get(
int $key,
): ?Tv;
If the key is not present, null is returned. If you would rather have an
exception thrown when a key is not present, use at()
instead.
Parameters
int $key
Returns
?Tv
- The value at the specified key; ornull
if the key does not exist.
Examples
This example shows how get
can be used to access an index that may not exist:
$v = Vector {'red', 'green', 'blue', 'yellow'};
// Index 0 is the element 'red'
\var_dump($v->get(0));
// Index 10 doesn't exist
\var_dump($v->get(10));
