>&#13;    PHP supports one execution operator: backticks (``). Note that
    these are not single-quotes! PHP will attempt to execute the
    contents of the backticks as a shell command; the output will be
    returned (i.e., it won't simply be dumped to output; it can be
    assigned to a variable).  Use of the backtick operator is identical 
    to <A

><B
CLASS="function"
>shell_exec()</B
></A
>.
