I have following arrays:
$keys
array (size=2)
0 => string 'foo' (length=3)
1 => string 'buz' (length=3)
$data
array (size=3)
'foo' => int 1
'bar' => int 2
'buz' => int 3
How to get $data array filtered by $keys values ? Desired output:
array (size=3)
'foo' => int 1
'buz' => int 3
array_intersect_key should be able to help you out here
array_intersect_key($data, array_flip($keys));
The array_flip is needed because array_intersect_key operates on keys, so this makes sure both arrays are in the right format.
