composer autoloader psr-0 namespaces

问题

I have create a custom composer package but I am having troubles to set the correct autoload options for it.

All my classes are under MyNamespace/Common namespace. So for example for including my ArrayHelper class I do use Mynamespace/Common/Helper/ArrayHelper.

This is the relevant part of my composer.json:

"autoload": {
    "psr-0": { "MyNamespace\\": "" }
} 

I have read this: composer.json / autoload

Any help?

回答1:

You have to navigate the file location of your namespace.

"autoload": {
    "psr-0": { "MyNameSpace": "./<path to your parent directory>" }
}

For example, this is my directory structure:

composer.json
source
  \-Data
    |-Controller
    \-Repository

Then, in the composer.json file:

"autoload": {
    "psr-0": { "MyNameSpace": "source/Data" }
}

Then, I can call the namespace from PHP by

/* namespace for classes in controller directory */
namespace MyNameSpace\Controller
/* namespace for classes in repository directory */
namespace MyNameSpace\Repository
