The usual solution is to wrap it with a closure.
function($x) { return array_key_exists('needle', $x); }
Or using the arrow function syntax:
fn($x) => array_key_exists('needle', $x)
The same trick also helps when you need to use functions with mandatory extra parameters, functions with pass-by-value parameters, etc.
