Fatal error: Call to undefined function gmp_sign() in php

I have tried to use gmp_sign in my file to find the sign of the value, but i getting an error like call to undefined function with fatal error.

Solution

  • Is it Ubuntu/Linux? Seems like GMP is not installed on the system. Follow these steps:

    1. Installed GMP with apt-get install php5-gmp

    2. Added extension=php_gmp.so to php.ini
