I have a problem with GCM, I can't send a message to all devices.
This isn't the original code, but is my own version!

Use this-
$fields = array(
'registration_ids' => $registatoin_ids,
'data' => array("message" => $message),
);
It says the data field needs to be an array, but you are setting it to $message, which is a string, not an array.
Field "data" must be a JSON array: You have just invited to play 'Soccer'
This means the value passed in data node is not a json.
Encoding $message into json will fix the error.

Your code was quite mixed up - you are requiring $_GET parameters in some places, $_REQUEST parameters in others and the curl function looks like it's attempting to send via POST - but there are options missing to force curl to send via POST. Using a simple GET request via curl with the parameters appended to the url the data gets inserted.
<?php
$sUrl = "https://returns.jabong.com/tracking/WebServices/server_input.php";
$sData = 'roll='.uniqid().'&name='.uniqid('user_',true);
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, $sUrl . '?' . $sData );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, FALSE );
$vRes = curl_exec($ch);
curl_close($ch);
echo $vRes;

Is there anything more optimized that i should be aware of ?
Is something missing in my code. Hosting people says that tomcat and mysql is consuming more task.
Here are my recommendations
1.- Always close the connection after retrieving the data.
2.- If you are expecting just one row for a query like this
"SELECT * FROM userDetails WHERE email = '$email' AND password = '$password'
you should add LIMIT 1 at the end of the query for retrieving the only possible row
3.-Add indexes to the table
4.-Test your performance with mysqlslap
Gcm message not sent to more that 1000 users , gcm has its own limit of sending message to 1000 users so the idea is to divide the users in batch of 1000 each i tried that but the gcm message is received by first 1000 users only how can we send the message in batches of 1000 each, in a total of say 5000 users, so that all users get the message i am new to php please explain the working
