could not load PEM client certificate, OpenSSL - php

Question

I have four files provided from client side.
test.jks
test.pem
key.pub
test.p12
I have to send json array on this url using curl. so i'm confused what is the use of other files ? like .p12 , .jks. what is the key from above files ?
I started with .pem file included using this link :
How to send a curl request with pem certificate via PHP?
So , I got following errors.
Error :
Curl Error: could not load PEM client certificate, OpenSSL error
error:0906D06C:PEM routines:PEM_read_bio:no start line, (no key found,
wrong pass phrase, or wrong file format?)No HTTP code was returned
Code :
$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, $tempPemPath);
//curl_setopt($ch, CURLOPT_SSLCERT, "test.pem" );
curl_setopt($ch,CURLOPT_SSLCERTTYPE,"PEM");
curl_setopt($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']];
}

Since you are using the filename - Try an absolute path.
e.g
curl_setopt($ch, CURLOPT_SSLCERT, 'c:/wamp64/www/bit-tool/www/testcert.pem');
