PHP Multidimensional Array push and loop

Question

I'm having some trouble understanding the coding in PHP, when it comes to multidimensional arrays and how to push. The idea is to push a "Attribute" and a "Attribute value"

I have tried the formula below

   $i = 0;
   $array = array();
    foreach($node as $a)
    {
        $strAtt = $node->PROP[$i]->attributes();
        $strVal = $node->PROP[$i]->PVAL;

        $output = $output.$strAtt." : ".$strVal."<BR>";
        $array[] = ($strAtt => $strVal);

The $array[] = ($strAtt => $strVal); doesnt give me much success. I have tried array_push($array, $strAtt => $strVal) - no luck..

As an extra questions, how do I loop trough the array and print me multidimensional values ?.

NEW CODE

while ($z->name === 'RECORD')
{

$node = new SimpleXMLElement($z->readOuterXML());

$Print = FALSE;
$output = "";
$i = 0;
foreach($node as $a)
{
    $strAtt = $node->PROP[$i]->attributes();
    $strVal = $node->PROP[$i]->PVAL;

    $output = $output.$strAtt." : ".$strVal."<BR>";
    $array[$strAtt] = $strVal;

    if(($i == 6) && ($node->PROP[$i]->PVAL == $ProductLookup))
    {
        $Print = TRUE;
        $Product = $node->PROP[$i]->PVAL;
    }       

    $i++;
}
if($Print == TRUE) {
    echo $output;
    echo "Product : ".$Product."<br>";
    var_dump($array);
    }

    //print_r($array);
    $print = FALSE;

// go to next <product />
$z->next('RECORD');
}

New code added. For some reason my $array is totally empty when i dump it, although my $Output is full of text ?

Answer 1

It sounds like you are wanting an "associative" array and not necessarily a multi-dimensional array. For associative arrays you don't use array_push. Just do this:

$array[$strAtt] = $strVal;

Then to loop the array just do this:

foreach ($array as $key => $value) {
    echo "$key = $value\n";
}

Answer 2

Go through array in php , you will understand how array works in php. Besides if you want to add an element to a multidimensional array you can achieve like this :

$node = array ("key1"=> array (a,b) , "key2"=> array (c,d));
$array = array();
foreach ($node as $key=>$value) {
    $array [$key] = $value;
}

This will be the resulting $array after the loop :

array (
"key1"=> array (
a,b
) , 
"key2"=> 
array (c,d)
)

Hope that helps , happy coding :)
