Indeed, that is the REPLACEMENT CHARACTER's code point.

However, the REPLACEMENT CHARACTER is not what is actually stored in the
string denoted by the literal "\0", which is the ASCII character NUL.
You can very this with var_dump(ord("\0\")).

See my reply to Toby (<[email protected]>) for further explanations.

You might it find useful to post general questions regarding PHP to
