|
<para>
|
|
<function>sqlite_udf_encode_binary</function> applies a binary encoding
|
|
to the <parameter>data</parameter> so that it can be safely returned from
|
|
queries (since the underlying libsqlite API is not binary safe).
|
|
</para>
|
|
<para>
|
|
If there is a chance that your data might be binary unsafe (e.g.: it
|
|
contains a NUL byte in the middle rather than at the end, or if it has and
|
|
<literal>0x01</literal> byte as the first character) then you must
|
|
call this function to encode the return value from your UDF.
|
|
</para>
|
|
<para>
|
|
PHP does not perform this encode/decode operation automatically as it would
|
|
severely impact performance if it did.
|
|
</para>
|
|
<note>
|
|
<para>
|
|
Do not use <function>sqlite_escape_string</function> to quote strings
|
|
returned from UDF's as it will lead to double-quoting of the data. Use
|
|
<function>sqlite_udf_encode_binary</function> instead!
