Question

I can’t use simply get_class_vars() because I need it to work with PHP version earlier than 5.0.3 (see http://pl.php.net/get_class_vars Changelog)

Alternatively: How can I check if property is public?

Answer 1

This is possible by using reflection.

<?php

class Foo {
  public $alpha = 1;
  protected $beta = 2;
  private $gamma = 3;
}

$ref = new ReflectionClass('Foo');
print_r($ref->getProperties(ReflectionProperty::IS_PUBLIC));

the result is:

Array
(
    [0] => ReflectionProperty Object
        (
            [name] => alpha
            [class] => Foo
        )

)
