Accessing nth element of XML in PHP with SimpleXml

Question

I have an xml formatted like this:

  
    text
  
  

        

Answer 1

It seems SimpleXML distinguishes between numeric and non-numeric array offsets in a slightly different way to a normal PHP array, so you need to cast your variable to an integer first. (All input from the query string is a string until you tell PHP otherwise.)

$var = intval($_GET['var']);
echo $xml->foo[$var]->bar;

This will turn the string '1' into the integer 1, and should give the result you require.
