PHP: Arrays displayed as string

Question

I'm trying to parse xml result with php (DOM) :

stdClass Object
  (
 [GetBilletResult] => Array
  (
 [0] => stdClass Object
    (
        [tabGrilleHoraire] => stdClass Object
            (
                [tabDetailTarifArticle] => stdClass Object
                    (
                        [sNomArticle] => ARTICLE1
                        [tabDetail] => Array
                            (
                                [0] => stdClass Object
                                    (
                                        [sDetail] => Liste Pax [Âge:19]
                                        [sAgePax] => 19;
                                        ...
                                    )

                                [1] => stdClass Object
                                    (
                                        [sDetail] => Prix de Base
                                        [sAgePax] => 18;
                                        ...
                                    )

My code so far:

$processed = array();
foreach( $billets as $GetBilletResult )
    {
        $sNomProduit = $GetBilletResult->getElementsByTagName( "sNomProduit" )->item(0)->nodeValue;
        $sNomArticle = $GetBilletResult->getElementsByTagName( "sNomArticle" )->item(0)->nodeValue;
        $tabDetail = $GetBilletResult->getElementsByTagName( "tabDetail" );

        if (!isset($processed[$sNomProduit])) {
            $processed[$sNomProduit] = array();
        }
        $processed[$sNomProduit][] = array(
                                           'sNomArticle' => $sNomArticle,
                                           'tabDetail' => $tabDetail,
                                           );
    }

The loop to display the results (articles are regrouped by product):

foreach ($processed as $sNomProduit => $list) {
    echo "<h3> ".$sNomProduit."</h3>";
    foreach ($list as $item) {
        echo "<h5> ".$item['sNomArticle'] . "</h5>";
        foreach ($item['tabDetail'] as $node) {
            var_dump ($node->nodeValue);
        }
    }
}

Output (The arrays under "tabDetail" array are displayed as strings)

PRODUIT A

ARTICLE A1

string 'Liste Pax : Pax n°1 [Âge:19]19;ADULTE(12-59.99)00000' (length=54)

string 'Prix de Base240300000' (length=21)

...

You're using var_dump, is that intentional? Don't you just want echo? — Don't Panic

The arrays under "tabDetail" array should be displayed as arrays not strings — Clementine

@Don't Panic. This is not the problem. I'm using var_dump to check the result type. Replace it by echo doesn't fix the problem. — Clementine

This is my actual sample code and tabDetail array structure. — Clementine

In this part of your code:

foreach ($item['tabDetail'] as $node) {
    var_dump ($node->nodeValue);
}

If there are more child nodes under tabDetail, using $node->nodeValue will just get the textContent of the node and its descendants. If you want to print the items separately, you should be able to iterate over the childNodes and output their values.

foreach ($item['tabDetail'] as $node) {
    foreach ($node->childNodes as $child) {
        echo $child->nodeValue;
    }
}

Or get the value of specific nodes you want as you are doing in your earlier code:

foreach ($item['tabDetail'] as $node) {
    echo $node->getElementsByTagName( "sDetail" )->item(0)->nodeValue;
}

@dont-panic. The tabDetail array : link. How can i save it like that, as array of arrays ?

Don't Panic Over a year ago

You mean, instead of outputting the text, you want to save it to a variable?

Clementine Over a year ago

Exactly, and keep the original structure.

Clementine Over a year ago

I replaced echo $child->nodeValue; by $array1 = $child->nodeValue; array_push($arrayAll, $array1);. I can't add $child->nodeValue as keys

Don't Panic Over a year ago

I would suggest $arrayAll[$child->nodeName] = $nodeValue; if you want to get the keys as well as the values. I think that should work.
