......

I can parse it fine when parsing all items (simpleXML)

Now i want to get one item at the time.So i passing a var to my file like

file.php?start=1
file.php?start=2
etc

and i tried to access the current item

$xml->entry[$start] returns NULL

OR

 $xml->entry->{$start} returns NULL

but both returns NULL

I tried to access it directly

$xml->entry[1]
$xml->entry->{1}

and its working fine

Am i missing somehthing?

Answer 1

$_GET[‘start’] is perhaps not proper variable type, try type casting to integer.
