The goal of the Verify library is to provide a structure for good authorization and authentication practices using your own data sources. Verify provides interfaces you can program to and inject your own objects and data into the tool for evaluation.

Example Code

First off, we're going to make a user based on an object we already have. In most cases the values on a user (model or otherwise) are referenced as properties. To make this creation easier, Verify has a Simple subject class you can use. You'll see this in the example below:

<?php

$user = (object)[
  'username' => 'ccornutt',
  'password' => password_hash('test1234', PASSWORD_DEFAULT),
  'permissions' => ['test1', 'test2', 'edit']
];
$subject = new \Psecio\Verify\Subject\Simple($user);

// Now we'll set up our Gateway to work with our user and run some checks
$gate = new Gateway($subject);

// We can see if the password they entered matches
echo 'Password match? '.var_export($gate->authorize($_POST['password']), true);

// And we can check their permissions with the "can" and "cannot" checks
if ($gate->can('edit') && $gate->cannot('delete')) {
    echo "We're here!";
}

// Or we can make it a bit more complex and include multiple
if ($gate->can(['edit', 'test1']) && $gate->cannot(['bar', 'test2'])) {
    /* Won't get here, the user has "test" so it fails */
} else {
    echo "This one fails!";
}

// Or, if you'd like to build up more of a policy:
$gate->allow('edit')->deny('test1234');
if ($gate->evaluate() === true) {
    echo 'Pass with flying colors!';
}

?>

The Verify library makes use of the PropAuth library behind the scenes. This library has a much more powerful engine than is just used here. If you have more "power" needs, check it out.
