APNS sandbox Connection failed error '0' in php file?
Am trying to send Apple Push Notifications to my app. Am following this tutorial for the APNS process. URL: http://www.raywenderlich.com/3525/apple-push-notification-services-tutorial-part-2.
I have done almost work in MAMP, PHP and i have mentioned my .pem file in pus_config.php file for APNS connection. I have tested my .pem file with simplepush.php file and i sent notifications to my device. Now am trying with push.php file which was taken from the above tutorial.
This is my push_config.php file,
<?php
// Configuration file for push.php
$config = array(
// These are the settings for development mode
'development' => array(
// The APNS server that we will use
'server' => 'gateway.sandbox.push.apple.com:2195',
// The SSL certificate that allows us to connect to the APNS servers
'certificate' => 'GopiAPNSCert.pem',
'passphrase' => 'gopi',
// Configuration of the MySQL database
'db' => array(
'host' => 'localhost',
'dbname' => 'gopipush',
'username' => 'gopipush',
'password' => 'uH4q9xQGNAuFW',
),
// Name and path of our log file
'logfile' => '/Users/gopi/Desktop/PushChatServer/log/push_development.log',
),
// These are the settings for production mode
'production' => array(
// The APNS server that we will use
'server' => 'gateway.push.apple.com:2195',
// The SSL certificate that allows us to connect to the APNS servers
'certificate' => 'ck.pem',
'passphrase' => 'secret',
// Configuration of the MySQL database
'db' => array(
'host' => 'localhost',
'dbname' => 'pushchat',
'username' => 'pushchat',
'password' => '1233}jfdoie',
),
// Name and path of our log file
'logfile' => '/Users/gopi/Desktop/PushChatServer/log/push_development.log',
),
);
The above certificate name and passphrase are verified and correct tested with simplepush.php file.
Here is my push.php file,
<?php

Am getting this error in my push_development.log file.
2012-05-14T18:04:28+05:30 Push script started (development mode)
2012-05-14T18:04:28+05:30 Connecting to gateway.sandbox.push.apple.com:2195
2012-05-14T18:04:29+05:30 Failed to connect: 0
I can't find what i did wrong? And what i should change in my push.php file. I have tested my network connection and .pem files. Can you please help me to solve this error and get notifications in my device? Thanks in advance.

Here i able to connect with apns and send notifications. So think no problems with .pem files.
Answer
[EDIT] Could you try setting the obsolute path to certificate file in config?
You can check this to solve peer verification issue.
Install the certificate http://code.google.com/p/apns-php/wiki/CertificateCreation#Verify_peer_using_Entrust_Root_Certification_Authority
Use here
stream_context_set_option($ctx, 'ssl', 'cafile', 'entrust_2048_ca.cer');
Note: Disable the verification also works.
