fsockopen error with php 7.0

I have updated my servers that have PHP 5.x to 5.6 and 7, then i got same error like above.

Try this:

Disable this code:

Code:

//PHP 5.3 Only
        /*
        $this->_smtp_connect = fsockopen($ssl.$this->smtp_host,
                            $this->smtp_port,
                            $errno,
                            $errstr,
                            $this->smtp_timeout);
        */

Add this lines below disabled codes:

Code:

//PHP 5.6 & 7.0 Only Configuration
$context = stream_context_create(['ssl' => [
  //'ciphers' => 'RC4-MD5',
  'verify_host' => FALSE,
  'verify_peer_name' => FALSE,
  'verify_peer' => FALSE
]]);

$this->_smtp_connect = stream_socket_client($ssl.$this->smtp_host.':'.$this->smtp_port, $errno, $errstr, 30, STREAM_CLIENT_CONNECT, $context);
//END OF PHP 5.6 & 7.0 Only Configuration

Hope this solves that problem. Thank you.
