FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught Error: Call to undefined function PHPBenchmark\bcadd() in /var/www/html/eduTrac-SIS/app/src/vendor/phpbenchmark/phpbenchmark/lib/PHPBenchmark/Utils.php:18

Answer 1

PHP does not recognize "bcadd()" gives the error. "bcadd()" function is included in "bcmath" PHP extention.

Just installing the relevant bcmath extension would solved the issue.

sudo apt-get install php7.0-bcmath

Please note, you should find the correct version of bcmath extension according to your PHP version. And restart apache

sudo service apache2 restart

Answer 2

For PHP 7.4- bcmath, install with apt or yum as below:

sudo apt install php7.4-bcmath

or

sudo yum install php7.4-bcmath
