PHP | Ds\Map putAll()函数
Ds\Map::putAll()函数是PHP中的一个内置函数,用于关联可遍历对象或数组的所有键值对。
句法:
void public Ds\Map::putAll( mixed $pairs )
参数:此函数接受单个参数$pairs是遍历对象或数组。
返回值:不返回任何值。
下面的程序说明了PHP中的Ds\Map::putAll()函数:
方案一:
putAll([
"a" => "Geeks",
"b" => "for",
"c" => "Geeks"
]);
print_r($map);
// Declare a new map
$map = new \Ds\Map();
$map->putAll([
"b" => "Computer",
"e" => "Science",
"f" => "Portal"
]);
print_r($map);
?>
输出:
Ds\Map Object
(
[0] => Ds\Pair Object
(
[key] => a
[value] => Geeks
)
[1] => Ds\Pair Object
(
[key] => b
[value] => for
)
[2] => Ds\Pair Object
(
[key] => c
[value] => Geeks
)
)
Ds\Map Object
(
[0] => Ds\Pair Object
(
[key] => b
[value] => Computer
)
[1] => Ds\Pair Object
(
[key] => e
[value] => Science
)
[2] => Ds\Pair Object
(
[key] => f
[value] => Portal
)
)
方案二:
putAll([
"Geeks1" => "computer",
"Geeks2" => "science",
"Geeks3" => 5,
"Geeks4" => 20
]);
var_dump($map);
// Declare a new map
$map = new \Ds\Map();
$map->putAll([
"x" => "A",
"y" => "B",
"z" => "C"
]);
var_dump($map);
?>
输出:
object(Ds\Map)#1 (4) {
[0]=>
object(Ds\Pair)#2 (2) {
["key"]=>
string(6) "Geeks1"
["value"]=>
string(8) "computer"
}
[1]=>
object(Ds\Pair)#3 (2) {
["key"]=>
string(6) "Geeks2"
["value"]=>
string(7) "science"
}
[2]=>
object(Ds\Pair)#4 (2) {
["key"]=>
string(6) "Geeks3"
["value"]=>
int(5)
}
[3]=>
object(Ds\Pair)#5 (2) {
["key"]=>
string(6) "Geeks4"
["value"]=>
int(20)
}
}
object(Ds\Map)#5 (3) {
[0]=>
object(Ds\Pair)#1 (2) {
["key"]=>
string(1) "x"
["value"]=>
string(1) "A"
}
[1]=>
object(Ds\Pair)#4 (2) {
["key"]=>
string(1) "y"
["value"]=>
string(1) "B"
}
[2]=>
object(Ds\Pair)#3 (2) {
["key"]=>
string(1) "z"
["value"]=>
string(1) "C"
}
}
