php - $_GET Breaks XML -

-

i'm using simpleviewer flash image gallery on site, , uses xml file information images displays.

for site, need dynamically generate xml, i'm using php file text/xml content-type declared. however, reason when access 1 of variables in $_get array simpleviewer tells me there no images in gallery, though when view source looks exact same , well-formed.

here's code:

$photos = array(  "1" => array("house1_1.jpg") ); foreach($photos[$_get["hid"]] $p){  echo ''; }

if replace $_get["hid"] "1" works fine, when make reference $_get returns error.

is there reason why accessing variable cause scripts linking xml (the simpleviewer flash) malfunction, , there way around this?

*note: "hid" variable 100% sure set "1", , there no php error. also, output looks same when use $_get["hid"] versus "1", difference simpleviewer script refuses see images there. also, stuff in empty quotes xml, don't know how appear in tags...

var dump of $photos , $_get, respectively:

array(1) {   [1]=>   array(1) {     [0]=>     string(12) "house1_1.jpg"   } } array(1) {   ["hid"]=>   string(1) "1" }

i first check , make sure $_get["hid"] returning "1". if it's possible not returning "1" should throw error accessing bad index of $photos.
