lob->close
Description
bool lob->close ( void )lob->close() closes descriptor of LOB or FILE. This function should be used only with lob->writeTemporary().
如果成功则返回 TRUE，失败则返回 FALSE。
注: In PHP versions before 5.0.0 you must use ocicloselob() instead. This name still can be used, it was left as alias of oci_lob_close() for downwards compatability. This, however, is deprecated and not recommended.
See also oci_lob_write_temporary().
