An error occurred while pushing apns-PHP iOS! Failedtoconnect: 13 Permissiondenied

{Code...} What is the problem !! Very urgent ~ Many of the methods mentioned on the Internet do not work, and a file is changed: {code...} and the above error occurs again. Indicates that the system is completely dizzy.

Warning: stream_socket_client() [function.stream-socket-client]: unable to connect to ssl://gateway.sandbox.push.apple.com:2195 (Permission denied) in /var/www/html/MyWork/apns/index.php on line 50Failed to connect: 13 Permission denied 

What is going on here !! Very urgent ~ Many methods mentioned on the Internet do not work.
Then I changed the file:

php\Warning: stream_socket_client(): Unable to set private key file `/var/www/html/MyWork/apns/cert.pem' in /var/www/html/MyWork/apns/index.php on line 50Warning: stream_socket_client(): failed to create an SSL handle in /var/www/html/MyWork/apns/index.php on line 50Warning: stream_socket_client(): Failed to enable crypto in /var/www/html/MyWork/apns/index.php on line 50Warning: stream_socket_client(): unable to connect to ssl://gateway.sandbox.push.apple.com:2195 (Unknown error) in /var/www/html/MyWork/apns/index.php on line 50Failed to connect: 0 

The above error occurs again. Indicates that the system is completely dizzy.

'Permission denied 'should be a Permission issue.
You can try to run it with the administrator privilege.

On the top floor, try root.

It has little to do with php and has nothing to do with ios... Permission problems

On linux, the permission is 777, or is it not a permission issue?
