Loop through object node with PHP [duplicate]

Question

I have an xml file with something like this:

<itens>
<item>
  <name>Ball</name>
  <color1>Yellow</color1>
  <color2>Black</color2>
  <color3>Red</color3>
</item>

...

</itens>

I'm already looping it using simplexml_load_file and than a foreach. So I'm able to echo $item->color1 and get Yellow. But what I need is to loop through those colors, something like:

for($x = 1; $x < 4; $x++){
  echo $item->color.$x;
}

Thanks a lot!

Whoever created that XML format must have misunderstood something very badly about element names. However you access elements by their name in SimpleXML, and if you want to have that name in a variable, see the PHP manual. Or one of the duplicate questions (just selected one of them for you, here is another one: stackoverflow.com/q/13440244/367456). In the PHP manual it's here: php.net/manual/en/language.variables.variable.php — hakre

echo $item->color.$x;

Won't work because it simply echoes $item->color and then appends $x. Try this instead

echo $item->{'colour'.$x};
