PHP Compilations directives

This is a suggestion of compilation directive to use when compiling PHP specifically for the audited code.

The selection made below is based on the extension usage, found in the code (--enable, --with) and also the absence of usage (--disable, --without).

Some local extensions (--pdo-mysql, --with-libmbfl...) are also mentionned for help.

# install 5 extra extensions
#pecl install libsodium (https://pecl.php.net/package/libsodium)
#pecl install php-psr (https://github.com/jbboehr/php-psr)
#pecl install suhosin.org (https://suhosin.org/)
#pecl install swoole-src (https://github.com/swoole/swoole-src)
#pecl install xhprof (https://pecl.php.net/package/xhprof)
