PHP Array只显示最后一个数组项目

Question

我有一个foreach循环（$ product_image）和一个数组（$ newProductData），我试图做的是将foreach内容（$ mediagalleryURLs）放入$ newProductData数组中，我的print_r $ newProductData时，输出显示只有最后的foreach元素作为$ newProductData [“media_gallery”]值，而不是完整的元素，这里是代码：

<?php 
... 

$resimURLNew = (string) $item->xpath('images/image[@main=1]')[0]; 

foreach($item->images->image as $product_image) { 
    $mediagalleryURLs = $product_image.';'; 
    $mediagalleryURLs = rtrim($mediagalleryURLs, ';'); 
} 

$newProductData = array(
    'sku'    => (string) $item->id, 
    'barcode'   => (string) $item->barcode 
); 

$newProductData['image']  = (string) $resimURLNew; 
$newProductData['small_image'] = (string) $resimURLNew; 
$newProductData['thumbnail'] = (string) $resimURLNew; 
$newProductData['media_gallery'] = $mediagalleryURLs; 

... 
?> 

Answer 1

您必须追加网址：

foreach($item->images->image as $product_image) { 
    $mediagalleryURLs .= rtrim($product_image) . ';'; 
} 

Answer 2

您将要覆盖的变量时，你应该将元素添加到您的阵列中：

$mediagalleryURLs = array(); 
foreach($item->images->image as $product_image) { 
    $mediagalleryURLs[] = rtrim($product_image.';', ';'); 
} 

Answer 3

试试这个，

$newProductData = array(
    'sku'    => (string) $item->id, 
    'barcode'   => (string) $item->barcode 
); 

foreach($item->images->image as $product_image) { 
    $mediagalleryURLs = $product_image.';'; 
    $mediagalleryURLs = rtrim($mediagalleryURLs, ';'); 
    $newProductData['media_gallery'] = $mediagalleryURLs; 
} 

$newProductData['image']  = (string) $resimURLNew; 
$newProductData['small_image'] = (string) $resimURLNew; 
$newProductData['thumbnail'] = (string) $resimURLNew;
