NumberTwo

NumberTwo is a classy variable dumper.

When var_dump or print_r is too verbose or unpleasant to read, go for NumberTwo.

Scalars

echo NumberTwo::dump(null);
// null

echo NumberTwo::dump(true);
// true
echo NumberTwo::dump(false);
// false

echo NumberTwo::dump(1);
// 1

echo NumberTwo::dump('foo');
// "foo"

Arrays

echo NumberTwo::dump(array('foo', 'bar'));

[
    0 => "foo"
    1 => "bar"
]

echo NumberTwo::dump(array('foo' => 'bar'));

[
    "foo" => "bar"
]

Objects

echo NumberTwo::dump($object);

My\ClassWithPublicProperties {
    foo: "aaa"
    bar: "bbb"
}

You can configure the recursive depth:

echo NumberTwo::dump($otherObject, 2);

UnitTest\NumberTwo\PublicProperties {
    foo: UnitTest\NumberTwo\PublicProperties {
        foo: UnitTest\NumberTwo\PrivateProperties { ... }
        bar: null
    }
    bar: null
}

Filters

You may want to pre-process some objects that are to be dumped.

For that, you can use the filters:

$filters = array(new MyFilter());

echo NumberTwo::dump($otherObject, 2, $filters);

Doctrine Collection

NumberTwo provides a filter for Doctrine's collections:

use NumberTwo\Filter\DoctrineCollectionFilter;

$filters = array(new DoctrineCollectionFilter());

echo NumberTwo::dump($otherObject, 2, $filters);

This filter will turn any Collection (ArrayCollection, PersistentCollection, …) into a PHP array (using the toArray() method).

Doctrine proxies

NumberTwo provides a filter for Doctrine's proxies:

use NumberTwo\Filter\DoctrineProxyFilter;

$filters = array(new DoctrineProxyFilter());

echo NumberTwo::dump($otherObject, 2, $filters);

This filter will load uninitialized proxies and clean up properties.

Feel free to submit other filters in a pull request.
