Actually if execute is async the Wiki is wrong:


    execute($app[, $arg][, $uuid])

    Execute a dialplan application, and wait for a response from the
    server. On socket connections not anchored to a channel (most of the
    time inbound), all three arguments are required -- $uuid specifies
    the channel to execute the application on.

    Returns an ESLevent object containing the response from the server.
    The getHeader("Reply-Text") method of this ESLevent object returns
    the server's response. The server's response will contain "+OK
    [Success Message]" on success or "-ERR [Error Message]" on failure.

    See the examples below for information on how to get a uuid to use
    when calling execute().

    executeAsync($app[, $arg][, $uuid])

    Same as execute, but doesn't wait for a response from the server.

    This works by causing the underlying call to execute() to append
    "async: true" header in the message sent to the channel. "

As you can see there is a specific executeAsync call documented. Are 
they both actually async?

That aside, does this code look OK?

$esl = new ESLconnection('localhost','8021','ClueCon');

$event = $esl->events('plain', 'ALL');
$event = $esl->filter("Unique-ID",$uuid);

sleep (2);

$event = $esl->execute("play_and_get_digits","4 11 1 5000 # 
ivr/ivr-that_was_an_invalid_entry.wav target_num \d+", "$uuid");

//$foo = $uuid . ' target_num';

while ($event->getType() != 'CHANNEL_EXECUTE_COMPLETE' ) {

$event=$esl->sendRecv("api uuid_getvar $uuid target_num");
