Question

I have a function foo that returns an array with the below structure and what I am trying to work out is there a better way to structure my PHP as I am unsure about the indexing within the foreach as I want every ListingId

Goal:

I am wanting to write a foreach loop that gets the XML <Name> from an external XML document (Have not coded this section yet as I need to pass the ListingID from foointo the url to get the <Name>)

PHP:

    $test0 = $this->foo();
    $test = $test0[0]['ListingId'];

Structure:

Array ( [0] => Array ( [ListingId] => SimpleXMLElement Object ( [0] => 532712629 ) [ListingCategory] => SimpleXMLElement Object ( [0] => 0350-5748-3400- ) ) [1] => Array ( [ListingId] => SimpleXMLElement Object ( [0] => 532712202 ) [ListingCategory] => SimpleXMLElement Object ( [0] => 0350-5748-3400- ) ) [2] => Array ( [ListingId] => SimpleXMLElement Object ( [0] => 532711566 ) [ListingCategory] => SimpleXMLElement Object ( [0] => 0350-5748-3400- ) ) [3] => Array ( [ListingId] => SimpleXMLElement Object ( [0] => 532710864 ) [ListingCategory] => SimpleXMLElement Object ( [0] => 0350-5748-3400- ) ) [4] => Array ( [ListingId] => SimpleXMLElement Object ( [0] => 532710271 ) [ListingCategory] => SimpleXMLElement Object ( [0] => 0350-5748-3400- ) ) [5] => Array ( [ListingId] => SimpleXMLElement Object ( [0] => 532691526 ) [ListingCategory] => SimpleXMLElement Object ( [0] => 0350-5748-3400- ) ) [6] => Array ( [ListingId] => SimpleXMLElement Object ( [0] => 527496168 ) [ListingCategory] => SimpleXMLElement Object ( [0] => 0350-5748-3399- ) ) ) 

Answer 1

Try this way:

foreach($this->foo() as $foo) {
   //here you can use your ListingId
   var_dump($foo['ListingId']);
}
