Database-Sql:php+mysql Support stacked query (stack queries)?

Stacked queries:executing more than one query in one transaction.
Is it a stack query to execute multiple SQL statements at a time?
See an article saying that Php+mysql does not support stacked queries, however, such an SQL statement: SELECT * FROM members; DROP members obviously in MySQL can be executed.
Do I get the wrong idea?

The database is sure to support stack queries, but letting PHP execute SQL statements is not necessarily OK.
