\Composer\AutoloadClassLoader

ClassLoader implements a PSR-0, PSR-4 and classmap class loader.

$loader = new \Composer\Autoload\ClassLoader();

// register classes with namespaces
$loader->add('Symfony\Component', __DIR__.'/component');
$loader->add('Symfony',           __DIR__.'/framework');

// activate the autoloader
$loader->register();

// to enable searching the include path (eg. for PEAR packages)
$loader->setUseIncludePath(true);

In this example, if you try to use a class in the Symfony\Component namespace or one of its children (Symfony\Component\Console for instance), the autoloader will first look for the class under the component/ directory, and it will then fallback to the framework/ directory if not found before giving up.

This class is loosely based on the Symfony UniversalClassLoader.

Parameters

array $classMap

add()

add(string  $prefix, array|string  $paths, boolean  $prepend = false)

Registers a set of PSR-0 directories for a given prefix, either appending or prepending to the ones previously set for this prefix.

Parameters

The prefix
array|string $paths

The PSR-0 root directories
boolean $prepend

Whether to prepend the directories

addPsr4()

addPsr4(string  $prefix, array|string  $paths, boolean  $prepend = false)

Parameters

string $prefix

The prefix/namespace, with trailing '\'
array|string $paths

The PSR-4 base directories
boolean $prepend

Whether to prepend the directories

Throws

\InvalidArgumentException

set()

set(string  $prefix, array|string  $paths)

Registers a set of PSR-0 directories for a given prefix, replacing any others previously set for this prefix.

Parameters

string $prefix

The prefix
array|string $paths

The PSR-0 base directories

setPsr4()

setPsr4(string  $prefix, array|string  $paths)

Registers a set of PSR-4 directories for a given namespace, replacing any others previously set for this namespace.

Parameters

string $prefix

The prefix/namespace, with trailing '\'
array|string $paths

The PSR-4 base directories

Throws

\InvalidArgumentException

setUseIncludePath()

setUseIncludePath(boolean  $useIncludePath)

Turns on searching the include path for class files.

Parameters

boolean $useIncludePath

getUseIncludePath()

getUseIncludePath() : boolean

Can be used to check if the autoloader uses the include path to check for classes.

Returns

boolean

setClassMapAuthoritative()

setClassMapAuthoritative(boolean  $classMapAuthoritative)

Turns off searching the prefix and fallback directories for classes that have not been registered with the class map.

Parameters

boolean $classMapAuthoritative

isClassMapAuthoritative()

isClassMapAuthoritative() : boolean

Should class lookup fail if not found in the current class map?

Returns

boolean

setApcuPrefix()

setApcuPrefix(string|null  $apcuPrefix)

APCu prefix to use to cache found/not-found classes, if the extension is enabled.

Parameters

string|null $apcuPrefix

getApcuPrefix()

getApcuPrefix() : string|null

The APCu prefix in use, or null if APCu caching is not enabled.

Returns

string|null

register()

register(boolean  $prepend = false)

Registers this instance as an autoloader.

Parameters

boolean $prepend

Whether to prepend the autoloader or not

unregister()

unregister()

Unregisters this instance as an autoloader.

loadClass()

loadClass(string  $class) : boolean|null

Loads the given class or interface.

Parameters

string $class

The name of the class

The name of the class

Returns

string|false —

The path if found, false otherwise

getRegisteredLoaders()

getRegisteredLoaders() : array<mixed,self>

Returns the currently registered loaders indexed by their corresponding vendor directories.

Returns

array<mixed,self>
