Quick PHP/Curl Fix Needed

I'm trying to grab this url via curl. It works as you can see on the curl CLI, but when I try it in my code it doesn't work.

% curl "http://data.fcc.gov/api/block/find?latitude=33.532559&longitude=-112.099305"
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><Response xmlns="http://data.fcc.gov/api" executionTime="0.072" status="OK"><Block FIPS="040131067003003B"/><County name="Maricopa" FIPS="04013"/><State name="Arizona" code="AZ" FIPS="04"/></Response>

$url = 'http://data.fcc.gov/api/block/find?latitude=' . $lat . '&longitude=' . $lng . '/';
		
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
		
print $result;

Code (markup):

It returns 'Not Found'. Any ideas?

 

try removing the forward slash from url

$url = 'http://data.fcc.gov/api/block/find?latitude=' . $lat . '&longitude=' . $lng;

 

Doesn't work. It still returns a Not Found message. I'm really frustrated and have been working on this for like 5 hours trying to get this curl stuff to work.

 

Odd. This worked:

$url = 'http://data.fcc.gov/api/block/find?latitude=' . $lat . '&longitude=' . $lng . "&format=json";
$output = file_get_contents($url);
