Conditional profiling

If you need to enable profiling based on some condition, you can use special variable ZIM_XHPROF_CONDITION

The value of this variable is passed to Symfony ExpressionLanguage component, with one variable called ctx. This expression must evaluate to bool value (true - enable profiling, false - disable)

CTX is initialized as follows:

$ctx->get = $_GET;
$ctx->post = $_POST;
$ctx->server = $_SERVER;
$ctx->cookie = $_COOKIE;

So for example to enable profiler only for your user session, you can use

ZIM_XHPROF_CONDITION='key_exists("PHPSESSID", ctx.cookie) && ctx.cookie["PHPSESSID"] === "bd465k5q41n8jsdd8iu99mmchk"'
