如何在一次循環迭代後插入數組？

Question

我有相關的產品陣列，每個都有一些網站，我想將它們全部存儲在一個數組中我的問題是，當foreach循環轉到其他相關產品時，它不會存儲另一個，並且我還使用$web[]和它會顯示我正確的一個，但在二維數組，因爲我初始化它作爲一個數組，然後再次我插入到其他數組。之所以我有$ web = array（）;是，它是被包括到其他代碼，所以我應該空我陣列所以就用這個method.the代碼的我的代碼部分和所述輸出是以下：

<?php 
echo "-------related----------<br>"; 
echo 'Productid: '.$productid."<br>"; 
$_product = Mage::getModel('catalog/product')->load($productid); 
$web= array(); 
foreach ($_product->getRelatedProducts() as $_product) 
{ 
echo 'Related Website ids for: '.$_product->getSku().'<br>';  
echo '<pre>website IDs in related:<br>'; 
echo "============="; 
$web+=$_product->getWebsiteIds(); 
echo "============="; 
print_r($_product->getWebsiteIds()); 
echo "=====inside array ===="; 
print_r($web); 
echo "<br>webcount in related:".print_r(count($web))."<br>"; 
} 
echo'<br>'; 
echo "Array OF ALL RELATED PRODUCTS:"; 

foreach($web as $key => $value) { 
    echo "<pre>"; 
    echo $key. "=>". $value; 
} 
echo "<br><br>COUNT".count($web); 
echo '</pre>'; 
echo "-------------------------"; 
?> 

輸出：

正如你所看到的第二個相關產品，我有3個項目，但它再次沒有任何差異的陣列

Answer 1

雖然你的問題是不完全清楚，但我想你想所有的網站id列表在一個單個一維數組。

在這種情況下，你可以使用

$web = array_merge($web, $_product->getWebsiteIds());
