问题
My app using Facebook SDK for PHP v2.0 stopped working since the past 20 - 24 hours. I keep getting the following error from the base_facebook.php -
CurlException: 35: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure
From reading the other threads on stackoverflow I added the following lines of code to base_facebook.php but none of these help.
$opts[CURLOPT_SSL_VERIFYPEER] = false;
$opts[CURLOPT_SSL_VERIFYHOST] = false;
$opts[CURLOPT_SSLVERSION] = 3;
curl_setopt($ch, CURLOPT_SSL_CIPHER_LIST, 'SSLv3');
Any suggestions to the fix the issue would be highly appreciated. Thanks.

It's because SSLv3 vulnerbility here: https://access.redhat.com/articles/1232123 Facebook disabled SSLv3 so, you cannot use it anymore.
If you have php 5.5 or 5.6, try change
$opts[CURLOPT_SSLVERSION] = 3;
to
$opts[CURLOPT_SSLVERSION] = CURL_SSLVERSION_TLSv1;
If you can use it without constant error, it's ok. If you have php version lower than 5.5, just comment these 2 lines out and it will be fine after that.
$opts[CURLOPT_SSLVERSION] = 3;
curl_setopt($ch, CURLOPT_SSL_CIPHER_LIST, 'SSLv3');
