PHP Multidimensional Array push and loop - php

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 :)
