• Application is using Composer.
• Classes can be autoloaded with Composer.
• PHP >= 5.3.0

^ Experimental.

* Planned.

** Not planned. Open an issue if you need this feature.

Examples

Standard Mode

<?php

require_once __DIR__ . '/vendor/autoload.php';

// Will default to ClassFinder::ALLOW_CLASSES
$classes = ClassFinder::getClassesInNamespace('TestApp1\Foo');
$classes = ClassFinder::getClassesInNamespace('TestApp1\Foo', ClassFinder::ALLOW_CLASSES);
$interfaces = ClassFinder::getClassesInNamespace('TestApp1\Foo', ClassFinder::ALLOW_INTERFACES);
$traits = ClassFinder::getClassesInNamespace('TestApp1\Foo', ClassFinder::ALLOW_TRAITS);
$funcs = ClassFinder::getClassesInNamespace('TestApp1\Foo', ClassFinder::ALLOW_FUNCTIONS);

// You can combine any of the flags
$interfacesTraits = ClassFinder::getClassesInNamespace('TestApp1\Foo', ClassFinder::ALLOW_TRAITS | ClassFinder::ALLOW_INTERFACES);

/**
 * array(
 *   'TestApp1\Foo\Bar',
 *   'TestApp1\Foo\Baz',
 *   'TestApp1\Foo\Foo'
 * )
 */
var_dump($classes);
/**
 * array(
 *   'TestApp1\Foo\BarInterface',
 *   'TestApp1\Foo\FooInterface'
 * )
 */
var_dump($interfaces);
/**
 * array(
 *   'TestApp1\Foo\BazTrait',
 * )
 */
var_dump($traits);
/**
 * array(
 *   'TestApp1\Foo\myFunc',
 * )
 */
var_dump($funcs);
/**
 * array(
 *   'TestApp1\Foo\BarInterface',
 *   'TestApp1\Foo\FooInterface',
 *   'TestApp1\Foo\BazTrait',
 * )
 */
var_dump($interfacesTraits);

Recursive Mode (in v0.3-beta)

<?php

require_once __DIR__ . '/vendor/autoload.php';

// As before, will default to ClassFinder::ALLOW_CLASSES
$classes = ClassFinder::getClassesInNamespace('TestApp1\Foo', ClassFinder::RECURSIVE_MODE);
$classes = ClassFinder::getClassesInNamespace('TestApp1\Foo', ClassFinder::RECURSIVE_MODE | ClassFinder::ALLOW_CLASSES);
$interfaces = ClassFinder::getClassesInNamespace('TestApp1\Foo', ClassFinder::RECURSIVE_MODE | ClassFinder::ALLOW_INTERFACES);
$traits = ClassFinder::getClassesInNamespace('TestApp1\Foo', ClassFinder::RECURSIVE_MODE | ClassFinder::ALLOW_TRAITS);
$funcs = ClassFinder::getClassesInNamespace('TestApp1\Foo', ClassFinder::RECURSIVE_MODE | ClassFinder::ALLOW_FUNCTIONS);


// You can combine any of the flags
$classesTraits = ClassFinder::getClassesInNamespace('TestApp1\Foo', ClassFinder::RECURSIVE_MODE | ClassFinder::ALLOW_CLASSS | ClassFinder::ALLOW_TRAITS);

/**
 * array(
 *   'TestApp1\Foo\Bar',
 *   'TestApp1\Foo\Baz',
 *   'TestApp1\Foo\Foo',
 *   'TestApp1\Foo\Box\Bar',
 *   'TestApp1\Foo\Box\Baz',
 *   'TestApp1\Foo\Box\Foo',
 *   'TestApp1\Foo\Box\Lon\Bar',
 *   'TestApp1\Foo\Box\Lon\Baz',
 *   'TestApp1\Foo\Box\Lon\Foo',
 * )
 */
var_dump($classes);

// You get the idea :)
var_dump($interfaces);
var_dump($traits);
var_dump($funcs);
var_dump($classesTraits);

Future Work

WARNING: Before 1.0.0, expect that bug fixes will not be backported to older versions. Backwards incompatible changes may be introduced in minor 0.X.Y versions, where X changes.

• psr0 support

• Additional features:

Various ideas:

• ClassFinder::getClassesInNamespace('TestApp1\Foo', ClassFinder::RECURSIVE_MODE). Providing classes multiple namespaces deep. (included v0.3-beta)

• ClassFinder::getClassesImplementingInterface('TestApp1\Foo', 'TestApp1\FooInterface', ClassFinder::RECURSIVE_MODE). Filtering classes to only classes that implement a namespace.

• ClassFinder::debugRenderReport('TestApp1\Foo\Baz') Guidance for solving "class not found" errors resulting from typos in namespaces, missing directories, etc. Would print an HTML report. Not intended for production use, but debugging.
