Escaping "?" in URL with PHP functions - php

Question

function prepareHeader($url, $method, $ctype = null)
{
$accInfo = json_decode(file_get_contents("etradeAccountInfo.json"), true);
$consumerKey = $accInfo['consumerKey'];
$consumerSecret = $accInfo['consumerSecret'];
$requestInfo = json_decode(file_get_contents("etrade_oauth.json"), true);
$oauth = array(
'oauth_consumer_key' => $consumerKey,
'oauth_nonce' => md5(mt_rand()),
'oauth_signature_method' => 'HMAC-SHA1',
'oauth_timestamp' => time(),
'oauth_version' => '1.0',
'oauth_token' => $requestInfo['oauth_token']
);
$base_info = buildBaseString($url, $method, $oauth);
$composite_key = rawurlencode($consumerSecret) . '&' . rawurlencode($requestInfo['oauth_token_secret']);
$oauth_signature = base64_encode(hash_hmac('sha1', $base_info, $composite_key, true));
$oauth['oauth_signature'] = $oauth_signature;
$header = array(buildAuthorizationHeader($oauth), 'Expect:', 'Accept:application/json', $ctype);
return $header;
}
$count100 = '?count=100';
$urlFragment = "accounts/$accountIdKey/portfolio";
$URL = $url . $urlFragment . $count100;
$header = prepareHeader($URL, 'GET');
// Prepare new cURL resource
$options = array(
CURLOPT_HTTPHEADER => $header,
CURLOPT_HEADER => false,
CURLOPT_URL => $URL,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_SSL_VERIFYPEER => false,
CURLOPT_CUSTOMREQUEST => "GET"
);
$feed = curl_init();
curl_setopt_array($feed, $options);
$response = curl_exec($feed);
// curl_close($feed);
print_r($response);
I'm trying to PHP CURL the following URL but it wouldn't work - it skipped the entire function above because of the ?count=100 if I were to take it out then it works fine... Here's the url I'm trying to curl it with https://api.etrade.com/v1/accounts/asdfsd34545/portfolio?count=100
any kind of help on this is greatly appreciated!
