找不到類/無法重新聲明類

Question

您好，我嘗試在我的laravel項目中包含某個文件中的某些類時遇到了一個奇怪的問題。這是文件：

<?php namespace Libraries\MPowerLib; 

require("mpower/dependency_check.php"); 

set_include_path(get_include_path() . PATH_SEPARATOR . realpath(dirname(__FILE__))); 

abstract class MPower { 
    const VERSION = "1.2.0"; 
} 

if (strnatcmp(phpversion(),'5.3.0') >= 0) { 
    define('JSON_ENCODE_PARAM_SUPPORT', true); 
}else{ 
    define('JSON_ENCODE_PARAM_SUPPORT', false); 
} 

require_once("mpower/setup.php"); 
require_once("mpower/customdata.php"); 
require_once("mpower/checkout.php"); 
require_once("mpower/checkout/store.php"); 
require_once("mpower/checkout/checkout_invoice.php"); 
require_once("mpower/checkout/onsite_invoice.php"); 
require_once("mpower/direct_pay.php"); 
require_once("mpower/direct_card.php"); 
require_once("mpower/libraries/Requests.php"); 
require_once("mpower/utilities.php"); 

現在，當我使用require_once我得到：

Class 'Libraries\MPowerLib\MPower_Checkout_Invoice' not found 

然而，當我只是需要它的工作原理使用，但我不斷收到此錯誤：

Cannot redeclare class libraries\mpowerlib\mpower_checkout 

我我完全爲此感到困惑，曾嘗試使用include和include_once代碼，但仍然沒有改變。

Answer 1

1.Add the mpower composer package to your composer.json file instead of adding the library manually 

    "require": { 
     "laravel/framework": "5.2.*", 
     "sirakoff/mpower_php":"dev-master" 
    }, 

2.Autoload the package by adding this to your composer.json file 

    "psr-0": { 
     "Sirakoff\\":["src/"] 
    } 

3. Set Mpower keys and Tokens in your controllers constructor method 

    public function __construct(){ 
     \MPower_Setup::setMasterKey("dd6f2c90-f075-012f-5b69-00155d866600"); 
     \MPower_Setup::setPublicKey("test_public_oDLVlm1eNyh0IsetdhdJvcl0ygA"); 
     \MPower_Setup::setPrivateKey("test_private_zzF3ywvX9DE-OSDNhUqKoaTI4wc"); 
     \MPower_Setup::setMode("test"); 
     \MPower_Setup::setToken("ca03737cf942cf644f36"); 

    } 


4. Now you can make use of the package in your controller 
    public function makePayment(Request $request) 
{ 
     $co = new \MPower_Checkout_Invoice(); 

     //addItem(name_of_item,quantity,unit_price,total_price,optional_description) 
     $co->addItem("13' Apple Retina 500 HDD",1,1.99,1.99); 
     $co->addItem("Case Logic laptop Bag",2,1.50,3.00,"Black Color with white stripes"); 
     $co->addItem("Mordecai's Bag",2,1.99,3.98); 

     $co->setTotalAmount(8.97); 

     $co->setDescription("Payment for general goods."); 

     $co->addTax("VAT (15)",50); 
     $co->addTax("NHIL (10)",50) 

     $co->addCustomData("Firstname","Alfred"); 
     $co->addCustomData("Lastname","Rowe"); 
     $co->addCustomData("CartId",929292872); 

     if($co->create()) { 
      //Your code here 
     } 


}
