我尝试在命令行中使用php-curl和curl连接curl但是我收到以下错误：
PHP脚本：
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://example.com/');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,2);
$page = curl_exec($ch);
echo 'Curl error: ' . curl_error($ch);
curl_close($ch);
ERROR：
Curl error: SSL read: errno -5938
命令行：
curl -v https://example.com
* About to connect() to example.com port 443 (#0)
* Trying IP_ADDRESS... connected

无法在任何地方找到任何有关这些错误的解释。
