sqlite_udf_decode_binary
Decode binary data passed as parameters to an UDF
&reftitle.description;
stringsqlite_udf_decode_binary
stringdata
Decodes binary data passed as parameters to a UDF.
You must call this function on parameters passed to your UDF if you need
them to handle binary data, as the binary encoding employed by PHP will
obscure the content and of the parameter in its natural, non-coded form.
PHP does not perform this encode/decode operation automatically as it would
severely impact performance if it did.
&reftitle.parameters;
data
The encoded data that will be decoded, data that was applied by either
sqlite_udf_encode_binary or
sqlite_escape_string.
&reftitle.returnvalues;
The decoded string.
