如何从数组键创建变量

Question

I am trying to extract the keys of an array as variables. I have following code for that:

01 |    $array = [
02 |        "bantya" => "BANTYA",
03 |        "sontya" => "SONTYA",
04 |        "niltya" => "NILTYA"
05 |    ];
06 |
07 |    function makeVar ($array) {
08 |        foreach ($array as $key => $value) {
09 |            $$key = $value;
10 |        }
11 |        echo $bantya;
12 |    }
13 |
14 |    makeVar($array);
15 |    echo $bantya;

The problem is, line 11 echoes "BANTYA" correctly, but the same about line 15 is not true. It says :

Notice: Undefined variable: bantya in file\path on line 15

My question is, why is it showing this error? How can I make line 15 to output "BANTYA" (which is outside of the scope of function makeVar($array)) globally after makeVar function is declared?

Thanks in advance..

I think that's will be helpful. Use extract() in PHP. See example below

$array = ( "bantya" => "BANTYA", "sontya" => "SONTYA", "niltya" => "NILTYA" ); extract($array); var_dump($bantya);

And you obtain new var: $bantya, $sontya, $niltya
