php - 将两个数组合并为一个数组

Question

我有以下代码，为 xml 源中的每个 RichText 元素创建两个数组。其中一个数组用于具有前缀的属性，另一个数组用于不具有任何前缀的属性。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

Array

        )

)

循环后我的array_merge创建了一个巨大的数组，其中有4个嵌套数组。两个数组是RichText的默认属性，另外两个数组是带有s7:前缀的属性。但我需要的是 $result 和 $result1 在 foreach 循环内合并，这样每个 $textNode 只有一个合并数组> 包含所有属性。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？

你的这段代码:

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

逻辑上属于你的 foreach 循环内部，我猜你几乎知道。然而，它在那里不起作用。 SimpleXML 喜欢返回可迭代的 SimpleXMLElement 对象，但它们本身不是数组，因此我们需要用其他东西替换 array_merge 。

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; 
    } 
}
