Question

我正在尝试获取包含其各自产品的子类别列表。如果我有50个产品和3个类别，则该代码有效。问题是：如果我有1500多种产品，分为6类，我的代码将返回一个错误页面，显示加载所需的等待时间（我认为）。

这是我的代码：

        $prodotti = '';
        foreach ($children as $chi){
        $prodotti .= '
        <div style="">
        <table style="width: 100%">
            <tr>
                <th align="left">
                  '.$chi[name].'
                </th>
                <th></th>
                <th></th>
            </tr>
            <tr>
               <th style="width: 80%">
                  Prodotto
               </th>
               <th align="right" style="width: 10%">
                  N. Valori
               </th>
               <th align="right" style="width: 10%">
                  Prezzo
               </th>
            </tr>';
            foreach ($products as $pro){
                if(in_array($chi[id_category],Product::getProductCategories($pro[id_product]))){
                      $prodotti .= '
                        <tr>
                           <td style="font-size: 9pt; color: #9E9F9E">
                              '.$pro[name].'
                           </td>
                           <td align="right" style="font-size: 9pt; color: #9E9F9E">
                           ...
                           </td>
                           <td align="right" style="font-size: 9pt; color: #9E9F9E">
                            '.$my_currency_iso_code.'
                            '.$pro[price].'
                           </td>
                        </tr>'; 
                }
            }
        $prodotti.='
        </table>
    </div>';   
        }

谢谢，问候

@曲棍球

我不得不稍微更改一下代码。现在，代码将创建一个数组，在其中将找到与类别关联的产品，然后将通过smarty发送该数组。

我尝试使用microtime（）; ……但是，尽管我一直在寻找向导，但我不知道该操作。

返回的值如下：0.81050395965576

这是带有microtime（）实现的新代码：

public function __construct($id_lista, $smarty)
{
    $this->idlista = $id_lista;
    $this->smarty = $smarty;

    $this->id_lang = Context::getContext()->language->id;
    $idlang = $this->id_lang;
    $this->id_shop = Context::getContext()->shop->id;
    $idshop = $this->id_shop;

    /*********************************************************************/

    //Get $icpn['id_category'], $icpn['lista_name'], $icpn['id_currency']
    $icpn = Db::getInstance()->getRow('SELECT cate_list, lista_name, id_currency FROM '._DB_PREFIX_.'rec_ps_beta WHERE id_rec_ps_beta = "'.$id_lista.'"');

    //Update di listalink e lastupdate
    Db::getInstance()->execute('UPDATE '._DB_PREFIX_.'rec_ps_beta SET listalink = "'._PS_BASE_URL_._MODULE_DIR_.'recpsbeta/lista/'.$icpn['lista_name'].'.lista", lastupdate = CURRENT_TIMESTAMP WHERE id_rec_ps_beta = "'.$id_lista.'"');


    //VALUTA
    $context = Context::getContext();
    $currency = $context->currency;
    $id_pscurr = $currency->id;

    if($id_pscurr == $icpn['id_currency']){
        $converti = 0;
    }else{
        $converti = 1;
    }
    //segno valuta
    $setcurrency = new CurrencyCore($icpn['id_currency']);
    $sig_setcurr = $setcurrency->sign;   


    $this->cateinfo = Category::getCategoryInformations(explode(',', $icpn['cate_list']));

    $timecate_start = microtime(true);
    foreach($this->cateinfo as $cats){
            $products = Product::getProducts ($idlang, 0, 0, 'name', 'ASC', $cats['id_category'], true);

            foreach ($products as $pro){

                        if($converti == 0){ 
                            $price = $pro['price'];
                            $price = number_format($price, 2).' '.$sig_setcurr;
                        }
                        elseif($converti == 1){
                            $price = Tools::convertPrice($pro['price'],$id_setcurr);
                            $price = number_format($price, 2).' '.$sig_setcurr;
                        }

                        $products_arr[] = array ('ctid'=>$cats['id_category'],
                                        'name'=>$pro['name'],
                                        'price'=>$price
                                        );

            }           
    }
    $timecate_end = microtime(true);

    $this->$timecate_end_start = $timecate_end - $timecate_start; 
    $this->products_arr = $products_arr;
    $this->listaname = $icpn['lista_name'];       
}

我应该如何解释以下结果：0.81050395965576？

PHP，Prestashop，foreach涉及众多子类别和众多产品
