I will run some benchmarks (even though they may be flaky), but what would
be the fastest execution?

$search = array(
            "<!-- [$cmd] -->",
            "<!--[$cmd]-->",
            "<!-- {".$cmd."} -->",
            "<!--{".$cmd."}-->",
            "{".$cmd."}",
        );
$replace = STARTPHP." $action ".ENDPHP;
$tmpcontent = str_replace($search, $replace, $tmpcontent);

Or, if I created one expression that handled all of the five $search items
(since they are similar) and used preg_replace()?

Thanks!
