php - 将两个数组合并为一个数组

Question

RichText我有以下代码为我的 xml 源中的每个元素创建两个数组。其中一个数组用于带有前缀的属性，另一个数组用于没有任何前缀的属性。这是我能弄清楚如何做到这一点的唯一方法：

<?php
$url = "http://testvipd7.scene7.com/is/agm/papermusepress/HOL_12_F_green?&fmt=fxgraw";    
$xml = simplexml_load_file($url);       
$xml->registerXPathNamespace('default', 'http://ns.adobe.com/fxg/2008');
$xml->registerXPathNamespace('s7', 'http://ns.adobe.com/S7FXG/2008');
$textNode = $xml->xpath("//default:RichText[@s7:elementID]");

function pr($var) { print '<pre>'; print_r($var); print '</pre>'; }

$result = array();
$result1 = array();
foreach($textNode as $node){
    $result[] = $node->attributes('http://ns.adobe.com/S7FXG/2008');
    $result1[] = $node->attributes();

}

$text = array_merge($result,$result1);

pr($text);

?>

输出

我的array_mergeafter 循环创建了一个巨大的数组，其中包含 4 个嵌套数组。两个数组是 的默认属性RichText，另外两个数组是带s7:前缀的属性。但我需要的是$result并在 foreach 循环中合并，这样每个包含所有属性的$result1合并数组只有一个。$textNode因此，在这个示例 url 中，我最后应该有两个数组，因为只有两个RichText元素。

这可能吗？

您的这段代码：

$text[] = array_merge($result,$result1);

正如我猜你几乎知道的那样，逻辑上属于你的 foreach 循环内部。但是，它在那里不起作用。SimpleXML 喜欢返回可以迭代的 SimpleXMLElement 对象，但本身不是数组，所以我们需要array_merge用其他东西替换。

总而言之：

$attributesByNode = array();

foreach($textNode as $node) {
    $result1 = $node->attributes('http://ns.adobe.com/S7FXG/2008');
    $result2 = $node->attributes();

    foreach ($result1 as $attribName => $attributeValue) 
    { 
        $attributesByNode[$attribName] = $attribVal; 
    } 
    foreach ($result2 as $attribName => $attributeValue) 
    { 
        $attributesByNode[$attribName] = $attribVal; 
    } 
}
