PHP add values from multidimensional array into one array-CodePudding

If I have an array $array like this:

Array ( 
    [0] => Array ( 
        [id] => 11 
        [name] => scifi 
        ) 
    [1] => Array (
         [id] => 12 
         [name] => documetary 
     ) 
    [2] => Array ( 
        [id] => 10 
        [name] => comedy 
    ) 
)

How could I turn it into simply:

Array ( 11, 12, 10 ) with no key value pairs.

I am trying to extract only the id from each array and add them into 1 array. I am trying it with a foreach;

$ids = [];

if ( $array ) {
  foreach ( $array as $item ) {
    $ids[] = $term->id;
  }
}

print_r($ids);

It just returns 3 empty arrays Array ( [0] => [1] => [2] => )

CodePudding user response：

Using a loop, you can do this:

$arr1 = [
 ['id'=>11,'name'=>'scifi'],
 ['id'=>12,'name'=>'documentry'],
 ['id'=>10,'name'=>'comedy'],
];

$arr2 = [];
foreach($arr1 as $internal){
  array_push($arr2,$internal['id']);
}

print_r($arr2);

Here we access all internal array's ID's and insert them into a new array.
