 New Comment:

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
