php组合数组本身

Question

why is php combining array when I do foreach. see below

If I enter the following code, I will get id1 id2 individually.

foreach($array as $value){
    $id = $value->id;
    echo $id;
}

now if I try to use the ids to do a query

foreach($array as $value){
    $id = $value->id;
    $result = $this->model->run_some_query($id);
    var_dump($result);
}

for the above code. Since I am foreach looping not passing in an array of ids, I expect to get 2 sets of seperate array. array1 with result from id1, array2 with result from id2. but instead I get 1 array with result from both id merged together.

How to make it so the array is seperated.

Answer 1

您可以通过这样做获得二维数组：

$result[id] = $this->model->run_some_query($id);

Answer 2

Is $this->model->run_some_query($id) returning an array reference, maybe? http://php.net/manual/en/language.references.php

Answer 3

you can try this code on your loop statement

foreach($array as $value){
  $id = $value->id;
  $result[] = $this->model->run_some_query($id);

}
var_dump($result);
