What Is the Best PHP Dom 2 Array Function

What is the best php DOM 2 Array function?

You can use this (based on: http://php.net/manual/en/book.dom.php#93717);

function xml_to_array($root) {
    $result = array();

    if ($root->hasAttributes()) {
        $attrs = $root->attributes;
        foreach ($attrs as $attr) {
            $result['@attributes'][$attr->name] = $attr->value;
        }
    }

    if ($root->hasChildNodes()) {
        $children = $root->childNodes;
        if ($children->length == 1) {
            $child = $children->item(0);
            if ($child->nodeType == XML_TEXT_NODE) {
                $result['_value'] = $child->nodeValue;
                return count($result) == 1
                    ? $result['_value']
                    : $result;
            }
        }
        $groups = array();
        foreach ($children as $child) {
            if (!isset($result[$child->nodeName])) {
                $result[$child->nodeName] = xml_to_array($child);
            } else {
                if (!isset($groups[$child->nodeName])) {
                    $result[$child->nodeName] = array($result[$child->nodeName]);
                    $groups[$child->nodeName] = 1;
                }
                $result[$child->nodeName][] = xml_to_array($child);
            }
        }
    }

    return $result;
}

Test;

$s = '<?xml version="1.0" encoding="UTF-8" standalone="no"?>
        <response>
            <resData foo="1">
                <contact:infData xmlns:contact="http://example.com/contact-1.0" bar="1">
                    <contact:status s="value1"/>
                    <contact:status s="value2"/>
                    <contact:status s="value3"/>
                    <contact:status s="value4"/>
                </contact:infData>
            </resData>
        </response>';

$xml = new DOMDocument();
$xml->loadXML($s);
$xmlArray = xml_to_array($xml);
print_r($xmlArray);
// print_r($xmlArray['response']['resData']['contact:infData']['contact:status'][0]['@attributes']['s']);
// foreach ($xmlArray['response']['resData']['contact:infData']['contact:status'] as $status) {
    // echo $status['@attributes']['s'] ."\n";
// }

What is the best way to move an associative array index to a different location

Not very elegant but it works:

$arr = array( 
    "foo" => "value1"    , 
    "bar" => "value2"    , 
    "baz" => "value3"    ,
    "qux" => "value4"
); 

$tmp = array();
foreach($arr as $k=>$v) {
    $tmp[] = array($k=>$v);;
}

array_splice($tmp, 1, 0, array_slice($tmp, 3));
array_splice($tmp, -1);
$arr = array();
foreach($tmp as $k => $v) {
    foreach($v as $k2 => $v2) {
        $arr[$k2] = $v2;
    }
}

print_r($arr);

output:

Array
(
    [foo] => value1
    [qux] => value4
    [bar] => value2
    [baz] => value3
)

xml php DOM get each parent node from loop

<?php

$xml = '
<tag>
    <item>
    <id>106</id>
    <title>DG</title>
    </item>
    <item>
    <id>105</id>
    <title>AC</title>
    </item>
</tag>
';

$dom = new DomDocument();
$dom->loadXML($xml);

// Using SimpleXML
$root = simplexml_import_dom($dom);
foreach ($root->xpath('//item') as $item) {
    $a = (array) $item;
    var_dump($a);
}

// Using plain DOM
foreach ($dom->getElementsByTagName('item') as $item) {
    $a = array();
    for ($i = 0; $i < $item->childNodes->length; ++$i) {
        $child = $item->childNodes->item($i);
        if ($child->nodeType == XML_ELEMENT_NODE) {
            $a[$child->tagName] = $child->nodeValue;
        }
    }
    var_dump($a);
}

Also take a look at this answer.

Replace value in array based on other array

Those are some interesting arrays because usually numeric arrays always have a 0. I imagine you may have some different key combination so I think this is the best "future-proof" method:

foreach ($optB as $i => $optB2) {
    foreach ($optB2 as $j => $val) {
        if ($val) {
            $opt[$i][$j] = '<strong>' . $opt[$i][$j] . '</strong>';
        }     
    }        
}
