The "\b" (backspace) isn't supported in double-quoted strings either. (That said, the
sequence is supported in json_decode() per the spec, https://www.json.org/json-en.html).

That doesn't look like a bug to me, but rather a feature request.

It would, but we have previously added \e, \v, \f, the first one in 5.4. I think it's an
acceptable break for a minor or major.

Adding that would break backwards compatibility, so they will probably not do it without
overwhelming reason to, but you can always use "\7" instead.

Description:
------------
Despite the support for the completely useless \v (vertical tab), \a, which produces the familiar
terminal beep or flash that we all know and love, is conspicuously absent from PHP.
Test script:
---------------
<?php
echo "\a";
Expected result:
----------------
<terminal beeps/flashes/some other "alert" if supported>
Actual result:
--------------
\a
