FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package composer-autoload
Composer Autoload Tools
Provide a standard interface for accessing and reading Composer autoloaders.
WARNING: This API is not yet stable and may be subject to change.
Why Does This Library Exist?
While it is generally not considered best practice for an application to be aware of underlying autoloaders, accessing the autoloader is sometimes a necessity.
The primary use case behind the creation of this library was providing a Composer implementation of the PSR-0 Resource Locator.
Usage
Installation
Through Composer as dflydev/composer-autoload.
Requirements
- PHP 5.3+
API
ClassLoaderLocator Class
Class Loaders
Direct access to Composer Class Loaders.
- Composer\Autoload\ClassLoader[] getClassLoaders(): Get all Composer Autoload Class Loader instances.
- Composer\Autoload\ClassLoader|null getFirstClassLoader(): Get the first Class Loader registered.
- Composer\Autoload\ClassLoader|null getFirstClassLoader(): Get the last Class Loader registered.
Class Loader Readers
Access to underlying Class Loaders through the Class Loader Reader Interface.
-
ClassLoaderReaderInterface getReader(): Get a ClassLoader Reader.
If multiple ClassLoaders or no Class Loaders are registered a Composite Class Loader Reader will be returned.
- ClassLoaderReaderInterface[] getReaders(): Get Class Loader Readers for each registered Class Loader.
- ClassLoaderReaderInterface getFirstReader(): Get the Class Loader Reader for the first Class Loader registered.
- ClassLoaderReaderInterface getFirstReader(): Get the Class Loader Reader for the last Class Loader registered.
Static Methods
-
init(): Initialize static instance.
Can be used to ensure that everything is setup before it is actually used at a later time. For example, if something may be going to modify the list of registered autoloaders, this will ensure that the Composer ones can be found and recorded right away.
-
reset(): Reset the static instance.
This effectively clears the located Class Loader instances. The next time something tries to access the class loaders the list of registered autoloaders will be scanned again.
-
set(array $classLoaders): Set the list of Class Loaders.
This is here primarily for testing purposes.
ClassLoaderReaderInterface
Mimics the data methods from Composer\Autoload\ClassLoader.
-
array getPrefixes(): Get namespace to directory mapping
-
array getFallbackDirs(): Get list of fallback directories
-
array getClassMap(): Get class mapping
- string|null findFile($class): Find the file for a specific class.
Gotchas
In some cases Composer's Class Loader may be replaced by another
autoload implementation. The common example for this is when a
specialized Debug Class Loader is registered on top of Composer.
In these cases it is advised to call init() immediately after
autload.php is required to ensure that Composer's Class Loader can
be located.
