你好，我在laravel项目的文件中尝试包含一些类时遇到了一个奇怪的问题。这是文件：
<?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");
现在，当我使用require_aonce时，我得到：
Class 'Libraries'MPowerLib'MPower_Checkout_Invoice' not found
然而，当我使用just-request时，它是有效的，但我一直得到这个错误：
Cannot redeclare class libraries'mpowerlib'mpower_checkout
我对此感到非常困惑，我曾经尝试过include和include_one的代码，但仍然没有改变。
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
}
}
