Composer - class not found after autoloading - php

Question

my class structure is as followed:
myproject
|
-------src (namespace PicoCore;)
|
-----objects (namespace PicoCore\Objects;)
-----tests (namespace PicoCore\Tests;)
I've created composer.json from autoloading:
{
"autoload": {
"psr-0": {
"PicoCore": "src",
"PicoCore\\Objects" : "src/objects",
"PicoCore\\Tests" : "src/tests"
}
}
}
I've created a testing script after installing:
<?php
require_once "../../vendor/autoload.php";
use PicoCore\Objects\User;
$user = new User();
$user->name = "asaf";
echo $user->name;
?>
User Class:
<?php
/**
* Created by PhpStorm.
* User: avivpaz
* Date: 12/25/14
* Time: 12:07 PM
*/
namespace PicoCore\Objects;
class User extends APIUser implements ConvertibleObjects
{
/**
* #var string User's Name
*/
public $name;
/**
* #var string User's Push Id
*/
public $pushId;
/**
* #var UserDevice User's device type
*/
public $userDevice;
/**
* #var double The location latitude
*/
public $latitude;
/**
* #var double The location longitude
*/
public $longitude;
public function __construct()
{
$this->label = USER_LABEL;
}
/**
* init with APIUser
* #param $APIUser APIUser
* #return User type
*/
public static function withAPIUser($APIUser)
{
$user = new User();
$user->label=USER_LABEL;
$user->id = $APIUser->id;
$user->facebookAccessToken = $APIUser->facebookAccessToken;
$user->picoAccessToken = $APIUser->picoAccessToken;
$user->accessTokenExpires = $APIUser->accessTokenExpires;
return $user;
}
public function ConvertObjectToCypherSyntax()
{
return '{id:"' . $this->id . '",name:"' . $this->name . '",picoAccessToken:"' . $this->picoAccessToken . '",accessTokenExpires:"' . $this->accessTokenExpires->getTimestamp() . '",latitude:' . $this->latitude . ',longitude:' . $this->longitude . '}';
}
static public function ConvertNodeToObject($results)
{
$user = new User();
if (is_null($results))
return $user;
$user->id = $results->getProperty('id');
$user->name = $results->getProperty('name');
$user->picoAccessToken = $results->getProperty('picoAccessToken');
$user->latitude = $results->getProperty('latitude');
$user->longitude = $results->getProperty('longitude');
// $user->userDevice = UserDevice::ConvertNodeToObject($results['userDevice']);
if (!$results->getProperty('accessTokenExpires') == "")
$user->accessTokenExpires = getDateTimeFromTimeStamp($results->getProperty('accessTokenExpires'));
return $user;
}
static public function ConvertArrayToObject($array) {
$user = new User();
if (array_key_exists("id", $array))
$user->id = $array["id"];
if (array_key_exists("name", $array))
$user->name = $array["name"];
if (array_key_exists("pico_access_token", $array))
$user->picoAcceessToken = $array["pico_access_token"];
if (array_key_exists("access_token_expires", $array))
$user->accessTokenExpires = getDateTimeFromString($array["access_token_expires"]);
if (array_key_exists("device_type", $array))
$user->deviceType = $array["device_type"];
if (array_key_exists("latitude", $array))
$user->latitude = $array["latitude"];
if (array_key_exists("longitude", $array))
$user->longitude = $array["longitude"];
if (array_key_exists("userDevice", $array))
$user->userDevice = UserDevice::ConvertArrayToObject($array["userDevice"]);
return $user;
}
public function toArray()
{
$user = array();
if (!empty($this->id))
$user["id"] = $this->id;
if (!empty($this->name))
$user["name"] = urldecode($this->name);
if (!empty($this->picoAccessToken))
$user["pico_access_token"] = $this->picoAccessToken;
if (!empty($this->accessTokenExpires))
$user["access_token_expires"] = getMysqlDateTime($this->accessTokenExpires);
if (!empty($this->latitude))
$user["latitude"] = $this->latitude;
if (!empty($this->longitude))
$user["longitude"] = $this->longitude;
if (isset($this->userDevice)) {
$userDevice = $this->userDevice->toArray();
if (!empty($userDevice))
$user["userDevice"] = $userDevice;
}
if (count($user) > 0)
return $user;
return null;
}
}
I get a can't find class exception.. any ideas ?

Answer 1

With PSR-0
In order to use PSR-0, you need to change your structure layout to:
src/
└── PicoCore
├── Objects
│   └── User.php
└── Tests
And in your composer.json you need to add PicoCore namespace:
"psr-0": {
"PicoCore\\": "src"
}
Alternative with PSR-4
If you want to keep your current file system layout, you can use PSR-4 instead of PSR-0. In order to use PSR-4, you need to update composer.json:
"autoload": {
"psr-4": {
"PicoCore\\": "src",
"PicoCore\\Objects\\" : "src/objects",
"PicoCore\\Tests\\" : "src/tests"
}
}
After you made your changes, run composer dumpautoload to regenerate autoload files.

Answer 2

If it's a namespace without class, it's must finish with \\
So :
"autoload": {
"psr-0": {
"PicoCore\\": "src",
"PicoCore\\Objects\\" : "src/objects",
"PicoCore\\Tests\\" : "src/tests"
}
}
and check file autoload
composer/autoload_namespaces.php
see https://getcomposer.org/doc/04-schema.md#psr-0
