lob->save
Description
bool lob->save ( string data [, int offset])Saves data to the large object. Parameter offset can be used to indicate offset from the beginning of the large object.
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 ocisavelob() instead. This name still can be used, it was left as alias of oci_lob_save() for downwards compatability. This, however, is deprecated and not recommended.
See also oci_lob_write() and oci_lob_import().
