php - Composer, PSR-4 Autoloading Itteration -

i running slim , twig, folder construction follow

/application/modules

in composer.json have

"autoload": { "psr-4": { "application\\": "application/modules/", "core\\": "application/", "middleware\\": "application/slim/middleware/" } }

my issue is in application\modules\ have directory each module. question is, possible create composer iterate through sub directories when using psr-4 autoload?

i see issue psr-4 declaration.

you shouldn't place "core" classes within folder has subfolders other namespaces.

psr-4 autoloading in composer works this: if qualified class name of class load matches prefix declared in of psr-4 definitions, prefix mentioned in prefix removed class name, , remaining class name mapped filename , beingness searched.

if have classes named application\ in folder application/modules, , have classes named core\ in folder application, technically composer might find files match class name core\modules\whatever, although these file contain class application\whatever instead.

i recommend moving core classes own folder , point in psr-4 declaration.

the problem original question omit of import information: class , file construction modules?

composer's autoloader happily resolve class starts namespace prefix application, remove prefix classname, convert remainders path name , search file in application/modules/. given have module class application\mymodule\foobar, searched in application/modules/mymodule/foobar.php. why? because prefix application removed allow shorter path names in psr-4. (using psr-0 mean have have folder every level of namespace in classname.)

note recommended optimum performance create prefix namespaces long possible, because composer allows have more 1 directory given prefix, has search right file in more 1 directory. searching files time consuming!

php composer-php autoload slim
