$ Dsn ['host'] = (isset ($ dsn ['host'])? $ Dsn ['host']: 'localhost ';

$ Dsn ['login'] = (isset ($ dsn ['login'])? $ Dsn ['login']: 'root ';

$ Dsn ['dbpwd'] = (isset ($ dsn ['dbpwd'])? $ Dsn ['dbpwd']: NULL;

$ Dsn ['db'] = (isset ($ dsn ['db'])? $ Dsn ['db']: 'test ';

$ Dsn ['Char '] = (isset ($ dsn ['Char'])? Str_replace ('-', NULL, $ dsn ['Char ']): 'utf8 ';

If ($ pconnect ){

If (! $ This-> link_id = @ mysql_pconnect ($ dsn ['host'], $ dsn ['login'], $ dsn ['dbpwd']) {

$ Halt & $ this-> getErrorMsg (_ LINE __);

}

} Else {
