boolhasNumericKeys(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'

boolisHashTable(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
boolIs an empty array() a valid hash table?
boolisList(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' ),
);

boolIs an empty list a valid list?
booliteratorToArray(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.

arraymerge(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.
