hasNumericKeys(mixed $value, bool $allowEmpty) : bool
A numeric key can be one of the following: - an integer 1, - a string with a number '20' - a string with negative number: '-1000' - a float: 2.2120, -78.150999 - a string with float: '4000.99999', '-10.10'

isHashTable(mixed $value, bool $allowEmpty) : bool
An array is a hash table if:
For example:
$hash = array(
'foo' => 15,
'bar' => false,
);
$hash = array(
1995 => 'Birth of PHP',
2009 => 'PHP 5.3.0',
2012 => 'PHP 5.4.0',
);
$hash = array(
'formElement,
'options' => array( 'debug' => true ),
);
mixed
bool
Is an empty array() a valid hash table?
bool
isList(mixed $value, bool $allowEmpty) : bool
A list is a collection of values assigned to continuous integer keys starting at 0 and ending at count() - 1.
For example:
$list = array( 'a','b','c','d' );
$list = array(
0 => 'foo',
1 => 'bar',
2 => array( 'foo' => 'baz' ),
);
mixed
bool
Is an empty list a valid list?
bool
iteratorToArray(array | \Traversable $iterator, bool $recursive) : array
Converts an iterator to an array. The $recursive flag, on by default, hints whether or not you want to do so recursively.
array\Traversable
The array or Traversable object to convert
bool
Recursively check all nested structures
\Zend\Stdlib\Exception\InvalidArgumentException |
if $iterator is not an array or a Traversable object |

array
merge(array $a, array $b) : array
If an integer key exists in both arrays, the value from the second array will be appended the the first array. If both values are arrays, they are merged together, else the value of the second array overwrites the one of the first array.
