[Varible and classes]

Been out of the "loop" for a while and running into trouble on day one.  Trying to figure it out.

 

Parsing Data from a url and getting   error message "Class '98007214' not found in"

-------------------------------------

code as follows

 

$corpid=array('98007214','98008630');

 

$x = 1;

while ($x<3)

{

 

$url="https://api.eveonline.com/corp/CorporationSheet.xml.aspx?corporationID=" .$corpid($x);

$data = file_get_contents($url);

$list = new SimpleXMLElement($data);

 

foreach ($list->result->corporationName as $result):

    echo $result;

endforeach;

$x=$x+1;

}

--------------------------

 

So it seems like the $corpid($x) expression is pulling the value it is supposed to be pulling.  but then the error is because its looking for a class?  Never had this issue back in the day and a bit confused on why its just not adding the varible in as text and creating a class error.
