Creates an blob object. BLOB's a renormally addressed by an object identifier which actually a pointer the the object iteself. This function creates the link between the BLOB and the file that is BLOB type is to contain.
The type paramter can be either 1 indicating TEXT data or 0 indicating BYTE data. The mode parameter can be either 0 indicating that the BLOB object holds the content in memory, or 1 indicating that the BLOB object holds the content in file.
If mode is set to 0, parameter must be a pointer to the content. Otherwise if mode is set to 1, the value for parameter must be a pointer to the filestring.
Example 558. Create a text and a byte BLOB
$db = ifx_connect("stores7@ol","informix","informix"); $text = "This is a very large amoutn of text data. Well, it could be :)"; // create param id for first blob column $tid = ifx_create_blob(0, 0, $text); // create param id for second blob column $bid = ifx_create_blob(0, 1, "/tmp/data.bin"); // store both param ids in the param param array $paramarray = $tid; $paramarray = $bid; // insert $query = "insert into testparams values (0, ?, ?)"; $result = do_query($query, $db, $paramarray); ifx_free_result($result); ifx_close($db);
