【中文标题】致命错误：无法声明类 ProductFilterIterator，因为该名称已在

【英文标题】：Fatal error: Cannot declare class ProductFilterIterator, because the name is already in use in

【问题描述】：

借助 ProductFilterIterator 类想要获取数据

class ProductFilterIterator extends \FilterIterator

    protected $filter;
    protected $length;

    public function __construct(\Iterator $iterator,  $filter)
    
        $this->filter = $filter;
        $this->length = -strlen($filter);
        parent::__construct($iterator);
    

    public function accept() : bool
    
        $current = $this->getInnerIterator()->current();
        return substr($current['Товар'], $this->length) == $this->filter;
    



$iterator = (new \ArrayObject($obj['items']))->getIterator();
$filter = new ProductFilterIterator($iterator, $arPart['ARTICLE']);

foreach ($filter as $obj) 
   echo "<pre>";

我收到一个错误 - 使用中

【问题讨论】：

你能指定你正在使用的框架吗？

你看过之前的教程了吗？ blog.floriancourgey.com/2018/05/…

因此，如果您在没有 Prestashop 的情况下工作，您需要将 Smarty 集成到您的系统中。

包括依赖packagist.org/packages/smarty/smarty和设置smarty.net/docs/en/installing.smarty.basic.tpl

这很难解释...

【参考方案1】：

尝试使用命名空间，

namespace Custom;
class ProductFilterIterator extends \FilterIterator

    protected $filter;
    protected $length;

    public function __construct(\Iterator $iterator,  $filter)
    
        $this->filter = $filter;
        $this->length = -\strlen($filter);
        parent::__construct($iterator);
    

    public function accept() : bool
    
        $current = $this->getInnerIterator()->current();
        return \substr($current['Товар'], $this->length) == $this->filter;
    



$iterator = (new \ArrayObject($obj['items']))->getIterator();
$filter = new ProductFilterIterator($iterator, $arPart['ARTICLE']);

foreach ($filter as $obj) 
   echo "<pre>";
