If (! $mysqli -> query ( "DROP TABLE IF EXISTS test" ) || ! $mysqli -> query ( "CREATE TABLE test(id INT)" )) while ( true ) // exit only on error or when there are no more queries to process The changes in the example comes after the creation of the string $sql.Įcho "Failed to connect to MySQL: (".
Or rather it just exits without reporting that one of the queries after the first query failed seeing that if a query fails next_result returns false. The example assumes that once the first query doesn't fail that the other queries have succeeded as well. Switching the first SELECT query with the INSERT query will result in a premature exit of the example with the message "Multi query failed: (0)". Multi_query only returns a non false response if a data/result set is returned and only checks for the first query entered.
