we have been developing an alternative (non-smtp) private mail system using PHP and JS. We use encryption (end-to-end, signing, etc) and we need to perform computations on arbitrary-precision numbers in PHP. Of course, there is the php_gmp module available and we use it, but we often receive signals from our users that this module is not installed in their hosting services.
The question is: do you know something about availability of php_gmp among various hosting services/providers?
Is there maybe a tool or a statistical web page which show such information for various php modules?
BTW: for us, alternative modules (php_bcmath for example) are a too slow and we would like to avoid using them.
Thank you in advance..
