从另一个类php调用类中的函数

I am very new to oops in php. Can anyone tell me how can i use a function

我是非常新的oops在PHP中。任何人都可以告诉我如何使用功能

    public static function getCategories($id_lang = false, $active = true,$order = true, $sql_filter = '', $sql_sort = '', $sql_limit = '')
            {
             if (!Validate::isBool($active))
             die(Tools::displayError());
             $result = Db::getInstance(_PS_USE_SQL_SLAVE_)->executeS('
              SELECT *
              FROM `' . _DB_PREFIX_ . 'category` c
              ' . Shop::addSqlAssociation('category', 'c') . '
              LEFT JOIN `' . _DB_PREFIX_ . 'category_lang` cl ON c.`id_category` = cl.`id_category`' . Shop::addSqlRestrictionOnLang('cl') . '
              WHERE 1 ' . $sql_filter . ' ' . ($id_lang ? 'AND `id_lang` = ' . (int)$id_lang : '') . '
              ' . ($active ? 'AND `active` = 1' : '') . '
             ' . (!$id_lang ? 'GROUP BY c.id_category' : '') . '
              ' . ($sql_sort != '' ? $sql_sort : 'ORDER BY c.`level_depth` ASC, category_shop.`position` ASC') . '
            ' . ($sql_limit != '' ? $sql_limit : '')
                      );

                if (!$order)
                   return $result;

                   $categories = array();
                   foreach ($result as $row)
                   $categories[$row['id_parent']][$row['id_category']]['infos'] = $row;

               return $categories;
              }

getCategories() is inside a class named class CategoryCore i want to use this getcategory into a new class totalDiscount in which a function called configure_products();

getCategories()在一个名为ClassClassCore的类中,我希望将这个getcategory用于一个新类totalDiscount,其中一个函数名为configure_products();

How can i use getcategory() inside the configure products?

如何在configure产品中使用getcategory()?

2 个解决方案

#1

include the class file on the page

在页面上包含类文件

You can create a object of the class inside another class

您可以在另一个类中创建该类的对象

function configure_products(){
    $categories = new CategoryCore();
    $categories->getcategory();
   // use $categories to do stuff 
     ......
     .....
}

OR

You can call it directly

你可以直接打电话

function configure_products(){
     $categories =   CategoryCore::getCategories();
     .....
     ....
}

#2

Your function getCategories() is a static function.

你的函数getCategories()是一个静态函数。

So, it can be called without creating object on teh class CategoryCore.

因此,可以在不使用类CategoryCore创建对象的情况下调用它。

You can use it as (using scope resolution operator):

您可以将其用作(使用范围解析运算符):

$categories = CategoryCore::getCategories(YOUR_ARGUMENTS)

$ categories = CategoryCore :: getCategories(YOUR_ARGUMENTS)
