(PHP 5, PECL OCI8 >= 1.1.0)
OCI-Lob::flush — Flushes/writes buffer of the LOB to the server
OCI-Lob::flush() actually writes data to the server.
By default, resources are not freed, but using flag
OCI_LOB_BUFFER_FREEyou can do it explicitly. Be sure you know what you're doing - next read/write operation to the same part of LOB will involve a round-trip to the server and initialize new buffer resources. It is recommended to use
OCI_LOB_BUFFER_FREEflag only when you are not going to work with the LOB anymore.
TRUE on success or
FALSE on failure.
FALSE if buffering was not enabled or an error occurred.
