<?php
function cli_beep()
{
echo "\x07";
}
?>
ncurses_beep

arplynn's function has a subtle bug, if it's being called while ob_start()'s output buffering is active, it does not make the system beep, and worse, it may corrupt whatever data is being generated under OB, by inserting an unprintable ascii character in it. use fprintf to STDOUT to bypass OB, eg
<?php
function cli_beep() {
fprintf ( STDOUT, "%s", "\x07" );
}
