1.2.1232. Typehints/CouldBeResource

Mark arguments, properties and return types that can be set to resource.

resource is an internal PHP type, and it should be a scalar type, yet it is not implement yet (as of PHP 8.2). It is still used as such by Exakat.

<?php

class x {
    // $p holds a resource
    private $p;

    function __construct() {
        $this->p = fopen('/tmp/file.txt', 'w+');
    }
}
?>
