    pg_close_stmt — Closes a prepared statement

    说明

    function pg_close_stmt(PgSql\Connection $connection, string $statement_name): PgSql\Result|false

    Closes a prepared statement on the server, freeing its resources and making its name available for reuse. It is an alternative to issuing a DEALLOCATE SQL command, which does not allow the statement name to be reused afterwards.

    This function is only available if PHP has been built against libpq 17 or later.

    参数

    connection

    PgSql\Connection 实例。

    statement_name

    The name of the prepared statement to close.

    返回值

    A PgSql\Result instance on success, or false on failure.

    错误／异常

    Throws a ValueError if statement_name is empty or contains any null bytes.
