PHP-ios，php推送报错

Question

php已经加载openssl模块，防火墙关闭，报错如下：

Warning: stream_socket_client() [function.stream-socket-client]: Unable to set local cert chain file `ck.pem'; Check that your cafile/capath settings include details of your certificate and its issuer in /web1/app/testdeom.php on line 31

Warning: stream_socket_client() [function.stream-socket-client]: failed to create an SSL handle in /web1/app/testdeom.php on line 31

Answer 1

如果php已经加载openssl模块，并且排除防火墙的原因。
原因：推送证书的问题。
1.确认你的推送证书没问题吗？
生成pem步骤：
1.下载下来你配置好的推送证书aps_developer_identity.cer 文件。
2.转换 .cer 文件到 .pem 文件:
openssl x509 -in aps_developer_identity.cer -inform der
-out PushChatCert.pem
3.在把你“钥匙”推送证书导出成的.p12到.pem文件:
openssl pkcs12 -nocerts -out PushChatKey.pem -in PushChatKey.p12
Enter Import Password:
MAC verified OK
Enter PEM pass phrase:
Verifying - Enter PEM pass phrase:
4.合并两个pem文件：cat PushChatCert.pem PushChatKey.pem > ck.pem
5.测试证书是否可用：
openssl s_client -connect gateway.sandbox.push.apple.com:2195
-cert PushChatCert.pem -key PushChatKey.pem

Answer 2

class pushNotifications {
...
private $sslPem = 'cert.pem';
...
function connectToAPNS(){
$streamContext = stream_context_create();
stream_context_set_option($streamContext, 'ssl', 'local_cert', dirname(__FILE__) . '/' . $this->sslPem);
