Fatal error: Call to undefined function bccomp()

Question

I am getting this error

PHP Fatal error: Call to undefined function bccomp()

I am using Ubuntu, and I installed PHP-5.6 using APT-GET command

Answer 1

bccomp() function belongs to BCMath package; if it's undefined, apparently, there's something wrong with the package itself. To be more specific, it's not enabled (as since PHP 4.0.4, libbcmath is bundled with PHP).

Quoting the docs:

These functions are only available if PHP was configured with --enable-bcmath.

The Windows version of PHP has built-in support for this extension. You do not need to load any additional extensions in order to use these functions.
