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

try
{
    require_once('push_config.php');

    ini_set('display_errors', 'off');

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.

Something that worked for me was updating the permissions on the ck.pem file so that the PHP script could read it correctly. Once done I could connect to APNS without any problems.

[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.
