Web Push PHP库错误

Question

I am trying to put push messages on my website with the PHP Push Web library.

• link to the git library
• Link to a video

Registration when accepting notifications works well. Save and delete if you have accepted or canceled the subscription to notifications.

The error appears when you try to send a message : First I installed GMP, it is well installed, but now it shows a different error with Vendor files.

Catchable fatal error: Argument 2 passed to Mdanter\Ecc\Primitives\CurveParameters::__construct() must be an instance of GMP, resource given
    called in /home/ubuntu/workspace/php_push_demo/vendor/mdanter/ecc/src/Curves/NistCurve.php on line 136 
    and defined in /home/ubuntu/workspace/php_push_demo/vendor/mdanter/ecc/src/Primitives/CurveParameters.php on line 39

Answer 1

To fix it I had to update my PHP 7.0 to 7.1 version. After that I haven't had any more problems.

You can get more information about the library here
