SSL在Windows上的PHP5.6中不起作用

Question

I tried:

$host = 'ssl://fbcdn-sphotos-c-a.akamaihd.net';
$port = 443;

$fp = fsockopen($host, $port, $errno, $errstr, 30);

if (!$fp) {
    var_dump($errno, $errstr);
} else {
    echo 'Connected';
}

And:

$host = 'ssl://fbcdn-sphotos-c-a.akamaihd.net:443';

$fp = stream_socket_client($host, $errno, $errstr, 30);

if (!$fp) {
    var_dump($errno, $errstr);
} else {
    echo 'Connected';
}

But both returns:

int(0)
string(0) ""

As if I had not been able to connect.

• I tried PHP5.6 for x86 and PHP5.6 for x64
• I used lastet release in http://windows.php.net/download#php-5.6
• In Linux it seems to work normally.
• This only occurs with some fields, others work well.
• PHP with CURL and SSL work fine in PHP5.6

Note: Strangely in php5.4 works perfectly.

Is a bug in this version of PHP?

Even PHP5.5 certificates works in a way in PHP, but after the PHP5.6 that has changed, as described in: http://php.net/manual/en/migration56.openssl.php

All encrypted client streams now enable peer verification by default. By default, this will use OpenSSL's default CA bundle to verify the peer certificate. In most cases, no changes will need to be made to communicate with servers with valid SSL certificates, as distributors generally configure OpenSSL to use known good CA bundles.

The default CA bundle may be overridden on a global basis by setting either the openssl.cafile or openssl.capath configuration setting, or on a per request basis by using the cafile or capath context options.

While not recommended in general, it is possible to disable peer certificate verification for a request by setting the verify_peer context option to FALSE , and to disable peer name validation by setting the verify_peer_name context option to FALSE .

The fsockopen try resolve connection using cafile , if php.ini is not configured, this show error 0 . You can try two solutions:

1. Configure php.ini:

   You can download https://curl.haxx.se/ca/cacert.pem and configure php.ini like this:

    openssl.cafile= "‪C:\\openssl\\cert\\cacert.pem" 

   Maybe you need restart Apache/Ngnix

2. Setup in execution time:

   Setup fsockopen is possible, but you can use fopen + stream_context_create , or use stream_socket_client .

   Note: sometimes the servers block functions like fopen and file_get_contents of access urls

   Example:

    <?php $opts = array( 'ssl' => array( 'verify_peer' => true, 'cafile' => 'C:/openssl/cert/cacert.pem', 'verify_depth' => 5, 'CN_match' => 'fbcdn-sphotos-ca.akamaihd.net' ) ); $context = stream_context_create($opts); $host = 'ssl://fbcdn-sphotos-ca.akamaihd.net:443'; $fp = stream_socket_client($host, $errno, $errstr, 30, STREAM_CLIENT_CONNECT, $context); if (!$fp) { var_dump($errno, $errstr); } else { echo 'Connected'; } 

   If you decide you need to disable checking for any reason, you can simply do this:

    <?php $host = 'ssl://fbcdn-sphotos-ca.akamaihd.net'; $port = '443'; $opts = array( 'ssl' => array( 'verify_peer' => false ) ); $context = stream_context_create($opts); $host = 'ssl://fbcdn-sphotos-ca.akamaihd.net:443'; $fp = stream_socket_client($host, $errno, $errstr, 30, STREAM_CLIENT_CONNECT, $context); if (!$fp) { var_dump($errno, $errstr); } else { echo 'Connected'; } 

Answer 2

http://php.net/stream_socket_client

If the value returned in errno is 0 and the function returned FALSE , it is an indication that the error occurred before the [system-level] connect() call. This is most likely due to a problem initializing the socket.
