Since you need a function reference for the callback, you'd actually need a
closure to capture the options:
$decode = function($data) { return json_decode($data, true); };
This is actually more effort and code than the existing version, so I'm not
sure what is gained.
Either way, the likelihood is you'd want to wrap this into a user function. As
I mentioned earlier, making it into an Iterator is often useful, and
potentially as simple as a generator function a bit like this:
function fjsoniterator($fh) {
if ( ! feof($fh) ) {
yield json_decode(fgets($fh), true);
}
}
$fh = fopen(...);
foreach ( fjsoniterator($fh) as $data ) { ... }
