merge two arrays into one array

Question

i have the following code that creates two arrays for each RichText element in my xml source. One of the arrays is for an attribute with a prefix, and the other array is for the attributes that do not have any prefixes. This is the only way I could figure out how to do it:

<?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);

?>

OUTPUT

                )

        )

)

My array_merge after the loop creates one huge array, with 4 nested arrays. Two arrays are the default attributes of RichText, and the other two arrays are the attributes that have a s7: prefix. But what I need is that $result and $result1 be merged inside the foreach loop, that way there is just one merged array for each $textNode containing all the attributes. Thus, in this example url I should have two arrays in the end because there are only two RichText elements.

Is this possible?

Answer 1

This bit of your code:

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

logically belongs to inside of your foreach loop as I guess you almost knew. However, it does not work there. SimpleXML likes to return SimpleXMLElement objects that can be iterated, but are not arrays themselves, so we need to replace array_merge by something else.

So all in all:

$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; 
    } 
}
