    odbc_free_result — Free resources associated with a result

    说明

    odbc_free_result(resource $statement): true

    Free resources associated with a result.

    odbc_free_result() only needs to be called if you are worried about using too much memory while your script is running. All result memory will automatically be freed when the script is finished.

    参数

    The result identifier.

    返回值

    总是返回 true。

    注释

    注意:

    If auto-commit is disabled (see odbc_autocommit()) and you call odbc_free_result() before committing, all pending transactions are rolled back.

    MDBTools driver needs you to properly free up a result_id before reusing a variable.
    An odbc_fetch_array() over a overwritten variable with a new result will crash the script with a Segmentation fault if the previous resource wasn't free'd up.
