    odbc_free_result — Free resources associated with a result

    Description

    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.

    Parameters

    statement

    The result identifier.

    Return Values

    Always returns true.

    Notes

    Note:

    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.
