MCVE is a credit card processing computer software library and interface running under the Red Hat operating system, replacing Red Hat's CCVS. It was built in to some older versions of PHP.[https://www.php.net/manual/en/book.mcve.php PHP Manual Entry on MCVE] ([https://web.archive.org/web/20190401060534/https://www.php.net/manual/en/book.mcve.php archived])
