Example #1 MysqlndUhConnection::getLastMessage() example
<?php
class proxy extends MysqlndUhConnection {
public function getLastMessage ( $res ) {
printf ( "%s(%s)\n" , __METHOD__ , var_export ( func_get_args (), true ));
$ret = parent :: getLastMessage ( $res );
printf ( "%s returns %s\n" , __METHOD__ , var_export ( $ret , true ));
return $ret ;
}
}
mysqlnd_uh_set_connection_proxy (new proxy ());
$mysqli = new mysqli ( "localhost" , "root" , "" , "test" );
var_dump ( $mysqli -> info );
$mysqli -> query ( "DROP TABLE IF EXISTS test" );
var_dump ( $mysqli -> info );
?>
以上例程会输出:
proxy::getLastMessage(array ( 0 => NULL, )) proxy::getLastMessage returns '' string(0) "" proxy::getLastMessage(array ( 0 => NULL, )) proxy::getLastMessage returns '' string(0) ""
