Easy PHP SimpleXML Issue

Question

I've got a really bad brain block with this.

My XML file looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<data>
  <fruits>
    <item>Apple</item>
    <item>Orange</item>
    <item>Banana</item>
  </fruits>
  <vegetables>
    <item>Lettuce</item>
    <item>Carrot</item>
  </vegetables>
</data>

I am tyring to use SimpleXML to retrieve an array containing "Apple, Orange, Banana". The code I am using is as follows:

$xml=simplexml_load_file('food.xml');

foreach($xml as $fruits=>$item) {
  $foodlist[] = $item;
}

print_r($foodlist); // Should display list of fruits.

But the list of fruits is not being stored to the array. What am I doing wrong?

Much thanks.

Answer 1

I've tested your code. It works fine for me. Another thing - it might be that you described it wrong, or might be that you understand this wrong. $foodlist should contain array of SimpleXML element objects (in your case " <fruits> " and " <vegetables> "), not array of fruits. If you want get only fruits you should access $xml->fruits->item; .

Edit: if you want to build an array of fruits try this:

$array = (array)$xml->fruits;
print_r($array['item']); // Should dipslay list of fruits

//or this
foreach ($xml->fruits->item as $fruit){
  $array2[] = (string) $fruit; //typecast to string, because $fruit is xml element object.
}
print_r($array2); // Should dipslay list of fruits

Answer 2

How about this:

foreach($xml->fruits->item as $item) {
    //$item has to be cast to a string otherwise it will be a SimpleXML element
    $foodlist[] = (string) $item;
}
print_r($foodlist);

I think this should give you what you're looking for, an array containing the text value of each of the item nodes that are children of the fruits node.

Answer 3

Try foreach( $xml['data'] as $fruits=>$item )

---- edit ----

foreach( $xml as $fruits => $item ) {
    if( $fruits == "fruits" )
        $foodlist[] = $item;
}
