Converts the map to an array.
Maps where non-scalar keys are can't be converted to an array.
An array will treat all numeric keys as integers,
eg. "1" and 1 as keys in the map
will only result in 1 being included in the array.
Note:
Casting to an array is not supported yet.
此函数没有参数。
An array containing all the values in the same order as the map.
Example #1 Ds\Map::toArray() example
<?php
$map = new \Ds\Map([
"a" => 1,
"b" => 2,
"c" => 3,
]);
var_dump($map->toArray());
?>
以上例程的输出类似于：
array(3) {
["a"]=>
int(1)
["b"]=>
int(2)
["c"]=>
int(3)
}
