php SimpleXml & arrays issue

Question

When I print_r($var) I get the result below.

SimpleXMLElement Object
(
    [SEND_FILE] => SimpleXMLElement Object
        (
            [FILEID] => 123
            [GUID] => 456
            [SUMMARY] => SimpleXMLElement Object
                (
                    [NB_PAYMENTS] => 1
                )
        )
)

How can I get the value of the FILEID element in a variable? If I do

print $result->SEND_FILE->FILEID[0]

then I just get the number - what I want, no mention of a SimpleXML Object. But if I put this variable in an array, as such

$res['file_id'] = $result->SEND_FILE->FILEID[0]

and then print_r($res) I get:

Array
    (
        [file_id] => SimpleXMLElement Object
            (
                [0] => 307466
            )
    )

How can I get it to remove the [0] / SimpleXMLElement Object?

SimpleXml is not an array. It only behaves remotely like one. — Gordon

Understood but ... I'm trying to send this array to a web service but the file_id key has to be just a numeric value, not an SimpleXML Object. — stef

This will look not too elegant, but try casting the result to integer (if the type is known):

$res['file_id'] = (int)$result->SEND_FILE->FILEID[0]

Confirmed, casting necessary in this case.

Why do you append the [0] at the end? You dont need that. You should simply do

print $result->SEND_FILE->FILEID;

And that should be enough.
