PHP-Curl错误：无法设置私钥文件：’test.pem’类型PEM

我的Pem文件是这种格式.

我正在使用这段PHP代码.我收到此错误.

Curl Error: unable to set private key file: ‘test.pem’ type PEM

码.

   $json_data  // it's a json array.

    $url = "https://adfapi.adftest.rightmove.com/v1/property/sendpropertydetails";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);

    // $pemFile = tmpfile();
    // fwrite($pemFile, "test.pem");   //the path for the pem file
    // $tempPemPath = stream_get_Meta_data($pemFile);
    // $tempPemPath = $tempPemPath['uri'];

    curl_setopt($ch, CURLOPT_SSLCERT, "test.pem"); 
    curl_setopt($ch,CURLOPT_SSLCERTTYPE,"PEM");
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/javascript'));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, True);
    curl_setopt($ch, CURLOPT_POST, True);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data);
    curl_setopt($ch, CURLOPT_VERBOSE, true);

    $result = curl_exec($ch);

    if(!$result)
    {
        echo "Curl Error: " . curl_error($ch);
    }
    else
    {
        echo "Success: ". $result;
    }

    $info = curl_getinfo($ch);

    curl_close($ch); // close cURL handler

    if (empty($info['http_code'])) {
            die("No HTTP code was returned"); 
    } else {
        // load the HTTP codes
        $http_codes = parse_ini_file("path/to/the/ini/file/I/pasted/above");

        // echo results
        echo "The server responded: <br />";
        echo $info['http_code'] . " " . $http_codes[$info['http_code']];
    }

我在线检查证书解码器：
https://www.sslshopper.com/certificate-decoder.html
并且证书在此站点上有效.

所以这里的问题是我无法解决.
我也尝试了ssl命令.

解决方法:

有两个错误.

>一个错误是pem文件,在pem文件生成中有一个错误.
>另一个错误是我没有在代码中包含CURLOPT_SSLCERTPASSWD().

码,

    curl_setopt($ch,CURLOPT_SSLCERTTYPE,"PEM");
    curl_setopt($ch, CURLOPT_SSLCERT, "test.pem");  
    curl_setopt($ch, CURLOPT_SSLCERTPASSWD, '******'); // password
