$param_nr
, string $data
) : boolAllows to send parameter data to the server in pieces (or chunks). This function can be called multiple times to send the parts of a character or binary data value for a column, which must be one of the TEXT or BLOB datatypes.
param_nr indicates which parameter to associate the data with.
Parameters are numbered beginning with 0.
data is a string containing data to be sent.
Note:
For efficiency reasons, this function should be used after calling maxdb_execute(). In this case, the data is not stored on the client side. The end of the sequence must end with a call to maxdb_stmt_close_long_data().
