Question

我有一个foreach循环（$ product_image）和一个数组（$ newProductData），我想要做的是将foreach内容（$ mediagalleryURLs）放入$ newProductData数组，当我print_r $ newProductData时，输出仅将最后一个foreach元素显示为$ newProductData [＆＃39; media_gallery＆＃39;]值，而不是完整元素，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

你必须追加网址：

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

Answer 2

当您要将元素附加到数组时，您将覆盖变量：

$mediagalleryURLs = array();
foreach($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;

PHP数组仅显示最后一个数组项
