This tries to mimic a very small subset of the functionality of CPAN's Exporter.

  x export_symbol
  x export_symbols

  Synopsis:
    
    define('EXPORT_OK', 'loadModule mkInstance' );
    require_once("php_extensions.php");
    

  Example output:

     Exporting symbol 'php::loadModule' to 'global::loadModule' (type='__php_function').
     selected stub:
    
     function &loadModule() { return php::loadModule(Exporter::wrap_args(func_get_args())); }
    

     Exporting symbol 'php::mkInstance' to 'global::mkInstance' (type='__php_function').
     selected stub:
    
     function &mkInstance() { return php::mkInstance(Exporter::wrap_args(func_get_args())); }
