Question

I have two arrays like this

 $arr1 = Array('fn', 'ln', 'em');
 $arr2 = Array('fn'=>'xyz',  'ano' => 'abc', 'ln'=>'122', 'em' => '[e-mail]', 'db'=>'xy');

I want to create an array from arr2 with all the elements from $arr1. So the result should be like this.

 $result = Array( 'fn'=>'xyz', 'ln'=>'122', 'em'='[e-mail]');

Don’t want to loop.

Any idea?

Answer 1

The order of arguments is important here

 print_r(array_intersect_key($arr2, array_flip($arr1)));
