Initiate a nonblocking query on a given connection
function mysql_async_query_start( string $query, resource $link_identifier = NULL, ): bool;
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.
bool- - TRUE if the query can properly be prepared and queued on the network.
