A short code to get an array that gets keys from one array and values from another in php

Question

Is there any neat way to make an array that its keys comes from the first array and its values come from the second, and discarding any item in the second that does not have any corresponding key in the first? for example if:

 $keys = array('key1'=>1,'key2'=>2,'key3'=>3);
 $vals = array('key1'=>'val1', 'key4'=>'val4');

the result would be:

 $result=array('key1'=>'val1' , 'key2'=>2 , 'key3'=>3);

Currently, I am using these two lines:

 $result = array_intersect_key($vals, $keys);
 $result = array_merge($vals, $result);

Is there any cleaner way to do that?

Answer 1

You're doing it correctly as is. To reduce a line you could do away with reassigning the $result variable like

 $result = array_merge($vals, array_intersect_key($vals, $keys));
