:::info[Note] This is a point-in-time snapshot of the API documentation from January 2026. Going forward, we will not be maintaining a public copy of these references, and recommend users to refer to the built-in signature helpers available in the Hack LSP instead for complete and up-to-date information. :::
mysql_multi_query() executes one or more queries separated by a ; to the currently active database on the server that's associated with the specified link_identifier
function mysql_multi_query(
string $query,
resource $link_identifier = NULL,
): mixed;
string $query - An SQL query
The query string should not end with a
semicolon. Data inside the query should be
properly escaped.resource $link_identifier = NULL - The MySQL connection. If the link
identifier is not specified, the last link
opened by mysql_connect() is assumed. If
no such link is found, it will try to
create one as if mysql_connect() was
called with no arguments. If no connection
is found or established, an E_WARNING
level error is generated.mixed - - This is a fb specific query so behaviour is a little random
at the moment.
