MCVE (Monetra) Payment Functions

LXXVIII. MCVE (Monetra) Payment Functions


These functions interface the MCVE (Monetra) API (libmonetra, formerly known as libmcve), allowing you to work directly with MCVE/Monetra from your PHP scripts. MCVE/Monetra is Main Street Softworks' solution to direct credit/debit/gift card processing for Linux/Unix/MacOSX/Windows ( ). It lets you directly address the credit card clearing houses via your *nix box, modem and/or internet connection (bypassing the need for an additional service such as Authorize.Net or Pay Flow Pro). Using the MCVE/Monetra module for PHP, you can process credit cards directly through MCVE/Monetra via your PHP scripts. The following references will outline the process.

Note: MCVE/Monetra is the replacement for RedHat's CCVS. They contracted with RedHat in late 2001 to migrate all existing clientele to the MCVE platform.

Note: This extension has been moved to the PECL repository and is no longer bundled with PHP as of PHP 5.1.0.

Note: This extension is not available on Windows platforms.


To enable MCVE (Monetra) Support in PHP, first verify your LibMonetra (formerly libmcve) installation directory. If you are compiling MCVE/Monetra support directly into PHP, you will then need to configure PHP with the --with-mcve option. If you use this option without specifying the path to your libmonetra installation, PHP will attempt to look in the default LibMonetra Install location (/usr/local). If Monetra (MCVE) is in a non-standard location, run configure with: --with-mcve=$mcve_path, where $mcve_path is the path to your MCVE/Monetra installation. Please note that MCVE/Monetra support requires that $mcve_path/lib and $mcve_path/include exist, and include mcve.h or monetra.h under the include directory and and/or libmcve.a and/or and/or libmonetra.a under the lib directory.

If you want to install MCVE/Monetra support as a module, you can do so by using the PECL repository, and issuing the 'pecl install mcve' command if you are running a PEAR version of at least 1.4.0.

Since MCVE/Monetra has true server/client separation, there are no additional requirements for running PHP with MCVE support. To test your MCVE/Monetra extension in PHP, you may connect to on port 8333 for IP, or port 8444 for SSL using the MCVE/Monetra PHP API. Use 'vitale' for your username, and 'test' for your password. Additional information about test facilities are available at
