Unable to set local cert chain file - php

Question

I have trouble with establishing a SSL connection.
These warnings are displayed:
Warning: stream_socket_client() [function.stream-socket-client]: Unable to set local cert chain file `D:\path\cert.pem'; Check that your cafile/capath settings include details of your certificate and its issuer in D:\path\testSll.php on line 23
Warning: stream_socket_client() [function.stream-socket-client]: failed to create an SSL handle in D:\path\testSll.php on line 23
Warning: stream_socket_client() [function.stream-socket-client]: Failed to enable crypto in D:\path\testSll.php on line 23
Warning: stream_socket_client() [function.stream-socket-client]: unable to connect to ssl://host.tld:700 (Unknown error) in D:\path\testSll.php on line 23
So I read all the question about the "Unable to set local cert chain file", but all the answer I found didn't work for me.
Here is the code I use :
$host = 'host.tld';
$port = 700;
$cert = dirname(__FILE__).'\\cert.pem'; //
$passe_phrase = 'pass';
$opts = array(
'ssl'=>array(
'local_cert' => $cert,
'passphrase' => $passe_phrase,
'verify_peer' => false
)
);
$context = stream_context_create($opts);
$fp = stream_socket_client('ssl://'.$host.':'.$port, $errno, $errstr, 30, STREAM_CLIENT_CONNECT, $context);
if ($fp) {
echo "OK";
} else {
echo "ERROR: $errno - $errstr<br />\n";
}
The certificate is the good one.
The script can access to the file cert.pem.
I cant find what I am missing here.
PHP version : 5.2.6

You should look at include details of your certificate and its issuer. In my case I accidentally deleted header of a file. When I return it back, the script is connecting successfully.
Before:
-----BEGIN CERTIFICATE-----

After

-----BEGIN CERTIFICATE-----
