(my current php page code at end of page) (using latest MODx Revolution)
I have a problem with converting a working PHP page into snippets, or generally MODx. As far as I know, snippets can handle PHP easily, and so far I converted all the echoes to returns and tested it out pretty much the same, and it didn’t work (it was called correctly as [[mysnippet]] but nothing shows up in the content area). I’ve tested out the page itself and it works. I actually have no clue how to convert this page to snippets/MODx, even after reviewing the docs on MODx.
My working php page in action (really basic right now):
http://www.hammerhead226.org/flickrtest/example.php
My php code: (with echoes intact)

$encoded_params = array();
foreach ($params as $k => $v){
$encoded_params[] = urlencode($k).'='.urlencode($v);
}
#
# call the API and decode the response
#
$url = "http://api.flickr.com/services/rest/?".implode('&', $encoded_params);
$rsp = file_get_contents($url);
$rsp_obj = unserialize($rsp);
if($rsp_obj['stat']=='ok') {
return($rsp_obj);

else{
return(false);
