Question

I’ve been pulling my hair out over this, I really hope I can get some help. Thanks in advance!

I have a SimpleXML object, which goes something like this:

Object
(
|    SomeStuff Object
|    (
|    )
|    Entries Object
|    (
|    |    Entry Object
|    |    (
|    |    |    SomeMoreStuff Object
|    |    |    (
|    |    |    )
|    |    |    ImportantStuff Object
|    |    |    (
|    |    |    |    W1 Object
|    |    |    |    (
|    |    |    |    |    D1 Object
|    |    |    |    |    (
|    |    |    |    |    )
|    |    |    |    |    D2 Object
|    |    |    |    W2 Object
|    |    |    |    (
|    |    |    |    |    D1 Object
|    |    |    |    |    (
|    |    |    |    |    )
|    |    |    |    |    D2 Object

…, etc.
For some reason, using the following code produces unexpected results:

foreach($xml->Entries->Entry->ImportantStuff as $key => $value) {
   echo "$key, $value";
}

Just outputs ImportantStuff, instead of a line for each D#. In another situation, I have an object where each member of ImportantStuff has the same name, and in this case I use $xml->ImportantStuff->ImportantThing, which returns all ImportantThings. How can I emulate this where the important things have different names?

Answer 1

using simplexml you need to do the foreach like this


foreach($xml->Entries->Entry->ImportantStuff->children() as $key => $value) {
echo "$key, $value";
}
