cubrid_lob2_export — Export the lob object to a file

Описание

cubrid_lob2_export ( resource $lob_identifier , string $file_name ) : bool

The cubrid_lob2_export() function is used to save the contents of BLOB/CLOB data to a file. To use this function, you must use cubrid_lob2_new() or fetch a lob object from CUBRID database first. If the file already exists, the operation will fail. This function will not influence the cursor position of the lob object. It operates the entire lob object.
