PHP uses apns feedback Service

1. the URL is different. The port is 2196.

2. Use the same certificate to establish a secure connection and accept the data until the data does not exist, similar to the table select operation.

3. Each record is a token. The server then deletes these device token records.

Access to the feedback service takes place through a binary interface similar to that used for sending push notifications. you access the production feedback servicefeedback.push.apple.com,
Port 2196; you access the sandbox feedback servicefeedback.sandbox.push.apple.com, Port 2196. As with the binary interface for push notifications, you must
Use TLS (or SSL) to establish a secured communications channel. the SSL certificate required for these connections is the same one that is provisioned for sending communications. to establish a trusted provider identity, you shoshould present this certificate
To apns at connection time using peer-to-peer authentication.

Once you are connected, Transmission begins immediately; you do not need to send any command to apns. begin reading the stream written by the feedback service until there is no more data to read. the specified ed data is in tuples having the following format:

Let's take a look at the feedback code:

public function receive(){$nFeedbackTupleLen = self::TIME_BINARY_SIZE + self::TOKEN_LENGTH_BINARY_SIZE + self::DEVICE_BINARY_SIZE;$this->_aFeedback = array();$sBuffer = '';while (!feof($this->_hSocket)) {$this->_log('INFO: Reading...');$sBuffer .= $sCurrBuffer = fread($this->_hSocket, 8192);$nCurrBufferLen = strlen($sCurrBuffer);if ($nCurrBufferLen > 0) {$this->_log("INFO: {$nCurrBufferLen} bytes read.");}unset($sCurrBuffer, $nCurrBufferLen);$nBufferLen = strlen($sBuffer);if ($nBufferLen >= $nFeedbackTupleLen) {$nFeedbackTuples = floor($nBufferLen / $nFeedbackTupleLen);for ($i = 0; $i < $nFeedbackTuples; $i++) {$sFeedbackTuple = substr($sBuffer, 0, $nFeedbackTupleLen);$sBuffer = substr($sBuffer, $nFeedbackTupleLen);$this->_aFeedback[] = $aFeedback = $this->_parseBinaryTuple($sFeedbackTuple);$this->_log(sprintf("INFO: New feedback tuple: timestamp=%d (%s), tokenLength=%d, deviceToken=%s.",$aFeedback['timestamp'], date('Y-m-d H:i:s', $aFeedback['timestamp']),$aFeedback['tokenLength'], $aFeedback['deviceToken']));unset($aFeedback);}}$read = array($this->_hSocket);$null = NULL;$nChangedStreams = stream_select($read, $null, $null, 0, $this->_nSocketSelectTimeout);if ($nChangedStreams === false) {$this->_log('WARNING: Unable to wait for a stream availability.');break;}}return $this->_aFeedback;}/** * Parses binary tuples. * * @param  $sBinaryTuple @type string A binary tuple to parse. * @return @type array Array with timestamp, tokenLength and deviceToken keys. */protected function _parseBinaryTuple($sBinaryTuple){return unpack('Ntimestamp/ntokenLength/H*deviceToken', $sBinaryTuple);}
