With getting data of related to tickers its works fine but when i am requesting for all users through curl request then its give me error:
我正在创建自己的系统来管理所有来自 freshdesk.com 通过其 API 的票证。我正在发出 curl 请求以从 freshdesk.com 获取数据。获取与代码相关的数据后，它工作正常，但是当我通过 curl 请求请求所有用户时，它给我错误：
Warning:curl_errno(): 2 is not a valid cURL handle resource in C:\wamp\www\test.php on line 28.
警告：curl_errno(): 2 不是第 28 行 C:\wamp\www\test.php 中的有效 cURL 句柄资源。
My code is like that:
我的代码是这样的：
$ch = curl_init();
$cOption = array(
CURLOPT_URL => 'http://velocity.freshdesk.com/contacts.xml',
CURLOPT_HEADER => 0,
CURLOPT_USERPWD => "$email:$password",
CURLOPT_POST => false,
CURLOPT_HTTPHEADER => array('Content-Type: application/xml'),
CURLOPT_HTTPAUTH => CURLAUTH_BASIC,
CURLOPT_FAILONERROR => 1,
CURLOPT_SSL_VERIFYHOST => 2,
CURLOPT_SSLVERSION => 2
);
@curl_setopt_array( $ch, $cOption );
curl_close($ch);
echo curl_errno($ch); //line 28
echo curl_error($ch); //line 29
echo $ch_result;
Output is:
Warning:curl_errno(): 2 is not a valid cURL handle resource in C:\wamp\www\test.php on line 28.
Warning:curl_errno(): 2 is not a valid cURL handle resource in C:\wamp\www\test.php on line 29.
1 // output of echo $ch_result
输出是：
警告：curl_errno(): 2 is not a valid cURL handle resource in C:\wamp\www\test.php on line 28.
Warning:curl_errno(): 2 is not a valid cURL handle resource in C:\ wamp\www\test.php on line 29.
1 // echo $ch_result 的输出
Please help me to figure out what is wrong with the code and why this warnings occur.
请帮我弄清楚代码有什么问题以及为什么会出现这种警告。

You use curl_errnoand curl_errorafter closing $ch. It is not right.
您使用curl_errno和curl_error关闭后$ch。这是不对的。
You need to close your $chafter fetching information about error.
您需要$ch在获取有关错误的信息后关闭您的。
echo curl_errno($ch);
echo curl_error($ch);
curl_close($ch);
Also you didn't set anything to $ch_result. If you expect that it contains result of your request you are wrong. To fix this you need to add option CURLOPT_RETURNTRANSFERand fetch the result with $ch_result = curl_exec($ch);
你也没有设置任何东西$ch_result。如果您期望它包含您的请求结果，那您就错了。要解决此问题，您需要添加选项CURLOPT_RETURNTRANSFER并获取结果$ch_result = curl_exec($ch);

echo curl_errno($ch);
echo curl_error($ch);
must be called before curl_close($ch);
必须先调用 curl_close($ch);

That's true I get the answer by this .
这是真的，我得到了这个答案。
$data = curl_exec($ch);
if (!curl_errno($ch)) {
....
}
curl_close($ch);
