Question

我有一个PHP应用程序，它在输入中使用CSV;在第一列中，我将类别和子类别分为“|”。我必须把这些东西放在一个Open Cart DB中，它有Category和Subcategory相同的表（列“parent_id”表示Category的category_id）。我想要构建一个包含所需字段的类，如下所示：

class Categorie {
    public $category_id;
    public $parent_id;
    public $image;
    public $top;
    public $column;
    public $sort_order;
    public $status;
    public $date_modified;
    public $date_added;
    public $language_id;
    public $name;
    public $description;
    public $meta_description;
    public $meta_keywords;
}

然后我分析数据：

$categorie = array();
while ( ( $riga_file = fgetcsv( $file, 100000, "\t" ) ) !== false )
{
     $array_el = count( $riga_file );
     for( $el_cur = 0; $el_cur < $array_el; $el_cur++ )
     {
         switch ( $el_cur )
         {
             case 0:
             $colonne = explode( "|", $riga_file[$el_corr] );
             $categoria = new Categorie();
             $categoria->image = "";
             $categoria->top = 1;
             $categoria->column = 1;
             // ... bla adding description data
             if( $categorie[$colonne[0]] == NULL ) // (1)
             {
                 $categoria->name = $colonne[0];
                 $categoria->category_id = $id_categoria;
                 $categoria->parent_id = 0;
                 $categorie[$colonne[0]] = $categoria;
                 $id_categoria++;
             }
             if( $colonne[1] != NULL ) // (2)
             {
                 $categoria->name = $colonne[1];
                 if( $categorie[$colonne[1]] == NULL )
                 {
                     $categoria->category_id = $id_categoria;
                     $categoria->parent_id = $categorie[$colonne[0]]->category_id;
                     $categorie[$colonne[1]] = $categorie;
                     $id_categoria++;
                 }
             }
             break;
         }

我应该有一个数组，里面填充了一系列独特的对象，如：

  // OUT(3)
  Category 1
  Subcategory 1
  Category 2
  Subcategory 2...

如果我在（1）和（2）中放入$ categoria（不是$ categorie）的回声，我会看到我在OUT（3）中记下的确切内容，这让我认为我的“引擎”是正确的。当我尝试搜索数组时会出现问题：

echo "<table border='1'>";
            foreach( $categorie as $value )
            {
                echo "<tr>
                           <td>$value->category_id</td>
                           <td>$value->parent_id</td>
                           <td>$value->name</td>
                      </tr>";
            }
            echo "</table>";

因为我根本没有获得类别，而且大多数但并非所有子类别。我在使用“搜索引擎”做错了什么，或者我误解了PHP Arrays的某些东西（可能是因为我来自C ++而且这个PHP是我的脑海中的一部分）？

Answer 1

我解决了问题，或更好：问题。

1）我拼错了变量：在（2）中我写道：

$categorie[$colonne[1]] = $categorie;

正确的写作是：

$categorie[$colonne[1]] = $categoria;

2）更大的问题来自于我对PHP的“不知情”，实际上修复了问题1，我得到了如下输出：

subcategory1
subcategory1
subcategory2
subcategory2

等等。这导致我在做的时候猜测：

$categorie[$colonne[1]] = $categoria;

PHP不会复制里面的值，而是使用地址。遵循正确的代码：

switch ( $el_corr )
                    {
                        case 0:                                                 // Categorie e sottocategorie
                            $colonne = explode( "|", $riga_file[$el_corr] );
                            $categoria = new Categorie();
                            $categoria->image = "";
                            $categoria->top = 1;
                            $categoria->column = 1;
                            $categoria->sort_order = 0;
                            $categoria->status = 1;
                            // Category_Description Campi
                            $categoria->language_id = 1;
                            $categoria->name = $colonne[0];
                            $categoria->description = "";
                            $categoria->meta_description = "";
                            $categoria->meta_keywords = "";
                            ////////////////////////
                            if( $categorie[$colonne[0]] == NULL )
                            //if( !trova_categorie( $colonne[0], $categorie ) )
                            {
                                $categoria->name = $colonne[0];
                                $categoria->category_id = $id_categoria;
                                $categoria->parent_id = 0;
                                $categorie[$colonne[0]] = $categoria;
                                $id_categoria++;
                            }
                            $categoria = new Categorie();
                            $categoria->image = "";
                            $categoria->top = 1;
                            $categoria->column = 1;
                            $categoria->sort_order = 0;
                            $categoria->status = 1;
                            // Category_Description Campi
                            $categoria->language_id = 1;
                            $categoria->name = $colonne[0];
                            $categoria->description = "";
                            $categoria->meta_description = "";
                            $categoria->meta_keywords = "";
                            if( $colonne[1] != NULL )
                            {
                                $categoria->name = $colonne[1];
                                if( $categorie[$colonne[1]] == NULL )
                                //if( !trova_categorie( $colonne[1], $categorie ) )
                                {
                                    $categoria->category_id = $id_categoria;
                                    $categoria->parent_id = $categorie[$colonne[0]]->category_id;
                                    $categorie[$colonne[1]] = $categoria;
                                    $id_categoria++;
                                }
                            }
                            break;
                    }
