If you want an associative version of this you can do the following:
function array_slice_assoc($array,$keys) {
return array_intersect_key($array,array_flip($keys));
}
However, if you want an inverse associative version of this, just use array_diff_key instead of array_intersect_key.
function array_slice_assoc_inverse($array,$keys) {
return array_diff_key($array,array_flip($keys));
}
Example:
$arr = [
'name' => 'Nathan',
'age' => 20,
'height' => 6
];
array_slice_assoc($arr, ['name','age']);
will return
Array (
'name' = 'Nathan',
'age' = 20
)
Where as
array_slice_assoc_inverse($arr, ['name']);
will return
Array (
'age' = 20,
'height' = 6
)
