When calling a API and converting the response to an associative array, the returned response can not be converted because of the extra boolean in the response. Only viewable when exit($response)

The options of the cURL operation are set using the @curl_setopt_array($ch, $array).

When checked for the header, it does not indicate any problem and it outputs the correct content (with content length)

When dumped the boolean is dumped with the correct response.

Test script:
// check if curl is available
if(!function_exists('curl_init')) throw new Exception('This method requires cURL (, it seems like the extension isn\'t installed.');
$url = '';

// set options
// 		$options[CURLOPT_URL] = (string) $url;
// 		$options[CURLOPT_USERAGENT] = 'PlonkHTTP '. self::version;
// 		$options[CURLOPT_FOLLOWLOCATION] = true;
// 		$options[CURLOPT_RETURNTRANSFER] = true;
// 		$options[CURLOPT_TIMEOUT] = 20;
// 		$options[CURLOPT_HEADER] = true;
		// init
		$curl = @curl_init();
// 		@curl_setopt_array($curl, $options);
		curl_setopt($curl,CURLOPT_URL, (string) $url);
		curl_setopt($curl,CURLOPT_RETURNTRANSFER, true);
		// execute
		$response = @curl_exec($curl);
		// fetch errors
		$errorNumber = @curl_errno($curl);
		$errorMessage = @curl_error($curl);
		// close

Expected result:
The script will result in a decent response on a local webserver. In a production environment, it gives the extra boolean when outputted.

Actual result:

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

The script work for me if I do a json_decode of $result. Can you give me the 
exact script you're using to get your problem (if it's not this one) but also the 
expected and actual result.
