Using Composer s Autoload

Question

I have been looking around the net with no luck on this issue  I am using composer s autoload with this code in my composer json    autoload          psr-0     AppName    src        But I need to autoload at a higher level than the vendor folder   Doing something like this does not work    autoload          psr-0     AppName       src        Does anyone know a fix or how I can do this

The autoload config does start below the vendor dir. So you might want change the vendor dir, e.g.

{
    "config": {
        "vendor-dir": "../vendor/"
    },
    "autoload": {
        "psr-0": {"AppName": "src/"}
    }
}

Or isn't this possible in your project?

The composer documentation states that      After adding the autoload field  you have to re-run install to   re-generate the vendor autoload php file    Assuming your  src  dir resides at the same level as  vendor  dir    src   AppName  vendor composer json   the following config is absolutely correct          autoload              psr-0     AppName    src              but you must re-update install dependencies to make it work for you  i e  run   php composer phar update   This command will get the latest versions of the dependencies and update the file  vendor composer autoload namespaces php  to match your configuration   Also as noted by  Dom  you can use composer dump-autoload to update the autoloader without having to go through an update

Just create a symlink in your src folder for the namespace pointing to the folder containing your classes     ln -s    src AppName   src AppName   Your autoload in composer will look the same      autoload          psr-0     AppName    src        And your AppName namespaced classes will start a directory up from your current working directory in a src folder now    that should work

Every package should be responsible for autoloading itself  what are you trying to achieve with autoloading classes that are out of the package you define   One workaround if it s for your application itself is to add a namespace to the loader instance  something like this    lt  php   loader   require  vendor autoload php    loader- gt add  AppName     DIR        src

In my opinion  Sergiy s answer should be the selected answer for the given question  I m sharing my understanding   I was looking to autoload my package files using composer which I have under the dir structure given below    lt web-root gt       --------src                   --------App                                     --------Test             ---------library             ---------vendor                                     ---------composer                               ---------autoload psr4 php                                               ----------autoload php            -----------composer json         I m using psr-4 autoloading specification   Had to add below lines to the project s composer json  I intend to place my class files inside src App   src Test and library directory    autoload              psr-4                  OrgName  AppType  AppName       src App    src Test    library                       This is pretty much self explaining  OrgName AppType AppName is my intended namespace prefix  e g for class User in src App Controller Provider User php -  namespace OrgName AppType AppName Controller Provider     namespace declaration  use OrgName AppType AppName Controller Provider User     when using the class   Also notice  src App    src Test     are from your web-root that is where your composer json is  Nothing to do with the vendor dir  take a look at vendor autoload php   Now if composer is installed properly all that is required is  composer update  After composer update my classes loaded successfully  What I observed is that composer is adding a line in vendor composer autoload psr4 php   vendorDir   dirname dirname   FILE       baseDir   dirname  vendorDir    return array       Monolog      gt  array  vendorDir     monolog monolog src Monolog         OrgName  AppType  AppName      gt  array  baseDir     src App    baseDir     src Test    baseDir     library         This is how composer maps  For psr-0 mapping is in vendor composer autoload classmap php

There also other ways to use the composer autoload features  Ways that can be useful to load packages without namespaces or packages that come with a custom autoload function   For example if you want to include a single file that contains an autoload function as well you can use the  files  directive as follows    autoload          psr-0                  src             SymfonyStandard    app               files     vendor wordnik wordnik-php wordnik Swagger php        And inside the Swagger php file we got   function swagger autoloader  className         currentDir   dirname   FILE         if  file exists  currentDir          className     php              include  currentDir          className     php         elseif  file exists  currentDir     models      className     php              include  currentDir     models      className     php           spl autoload register  swagger autoloader      https   getcomposer org doc 04-schema md files  Otherwise you may want to use a classmap reference          autoload              classmap     src     lib     Something php             https   getcomposer org doc 04-schema md classmap  Note  during your tests remember to launch the composer dump-autoload command or you won t see any change     composer phar dump-autoload   Happy autoloading
