出现错误：将变量传递到 Octobercms 闭包 function 时出现“未定义变量：var”

Question

I have looking a way to pass a variable inside a http client method. For example:

$response_send_email = Http::get('some url',function($http){
   $http->data(['id'=>$var]);
});

I have tried to pass the variable, but it always showed an error "Undefined Variable: var" . Before that, I have tried another way like this and it works:

$response_send_email = Http::get('some url',function($http){
       $http->data(['id'=>1]);
});

But I won't do that way because I will pass a random id. Thank You!

Answer 1

you need to use use keyword use ($var)

$var = 1; // <- outside scope variable
$response_send_email = Http::get('some url',function($http) use ($var) {
   $http->data(['id' => $var]);
});

if any doubt please comment.
