QUESTION
I an creating a PWA app and its working fine, but when I tried to upload on server I stuck on error. On windows local server, everything is fine even notifications, and I dont know much putty/linux commands.
check here my phpinfo file.
I am tring to upload to amazon ec2 server. I installed apache, php, ssl and other required things. And its working file except notifications.
When I call my notification file, I got 503 response. I installed composer, installed everything. I used this github library.
As I understand, I stuck on gmp extension, When I open phpinfo() I didnt see gmp over there. I installed gmp using sudo yum install php-gmp and also I see a file in php.d named as 20-gmp.ini and it included extension=gmp. Also restarted apache server using sudo apachectl stop, sudo apachectl start.
But still I am getting error. And I coudnt see gmp in phpinfo().

Answered 2019-Apr-27 at 09:38I know I am commenting my own question, As I was searching this answer for 3-4 days I think I should share this info with everyone.
The issue is, In linux, PHP have different-different configuration files. The main configuration file is php.ini. And it include other extensions after loading this file and override mail file. These additional configuration are located in /etc/php.d/ (in my case, which is common for mostly).
So just restarting apache server in not enough. We need to also restart php-fpm.
To restart php-fpm: sudo service php-fpm restart
And then restart apache: sudo apachectn restart

QUESTION
I am building a web push notification system and I am using the concept used in this example:
https://github.com/Minishlink/web-push-php-example
I have the following code in my JS file. It checks for API support, checks if notifications are not disabled, registers the service worker, asks for permission to display notifications, if allowed subscribes the user and sends the details to the server. If the user is already subscribed, it updates the endpoint value in the DB.
When I run this on Firefox 61, it works fine, but when I run it on Chrome 67 I get this error:

const key = subscription.getKey('p256dh');
const token = subscription.getKey('auth');
const contentEncoding = (PushManager.supportedContentEncodings || ['aesgcm'])[0];
return fetch('/scripts/notification-subscribe.php', {
method: 'POST',
body: JSON.stringify({
endpoint: subscription.endpoint,
publicKey: key ? btoa(String.fromCharCode.apply(null, new Uint8Array(key))) : null,
authToken: token ? btoa(String.fromCharCode.apply(null, new Uint8Array(token))) : null,
contentEncoding,
user: 1,
}),
}).then(() => subscription);
}
}
Just modify this function hope pushSubscription with if block it works

...ANSWER
Answered 2018-Sep-21 at 11:13Are you absolutely sure you are actually running PHP 7.21 or 7.2? The problem is the question marks in the constructor here:
https://github.com/web-push-libs/web-push-php/blob/master/src/Subscription.php#L41-L43
As you can see from this 3v4l code, it works on all versions over 7.1:
