That's not obvious, in fact it shouldn't equal chr(9) unless I'm missing an
extra section in the string parsing rules. That's the literal string "\9"
(length 2, slash followed by nine).
andyh@server ~/public_html $ cat test.php
<?php
var_dump("\9");
?>
andyh@server ~/public_html $ php -q test.php
string(2) "\9"

\132
As with Perl, C and C++, you use octal in this type of escape sequence.

(scroll down to table 11-1).
