Access object protected properties

adnan - 2 months ago

Well, sometimes you just needed to access the value of a protected property of a class that you can't modify, .. out of absolute necessity,

Here's one one way of doing it,

 /**
  * Read a protected property value in a class instance
  *
  * @param    string or object $instance, the class string or an instance
  * @param    string $property, property name
  * @return    mixed
  */

    function read_protected_property($instance, $property)
    {
      return ((array) is_string($instance) ? app($instance) : $instance)[chr(0).'*'.chr(0) . $property];
    }

You can pass it either an object or a class string,

$IconRegistry = read_protected_property('Anomaly\Streams\Platform\Ui\Icon\IconRegistry', 'icons');

I'm writing a simple module that would allow users to easily extend the Icons Registry, will announce soon,

You can extend the icon registry yourself by resolving and using: https://github.com/anomalylabs/streams-platform/blob/master/src/Ui/Icon/IconRegistry.php#L175

Silly goose.

app(\ Anomaly\Streams\Platform\Ui\Icon\IconRegistry::class)->register('silly-goose', 'fa fa-silly');

Stuff it into a service provider or something somewhere.

Thanks for that Ryan, love the silly goose example, hh ..

What I wanted was to manage the Icons Registry from the Database, so a Module would need access to the list of icons in IconRegistry when running the seeder, .. for that, there's no other way than having to access a protected property,

Well, you don't want to see my initial attempts at this, .. file_get_contents, eval, regx would give you an idea of how messy that was hh
