Make php script return continuous events?

[jsherk]

I am working a php script that I want to record all events (will work on filters later) as they occur. In my script below though, I loop for 5 seconds and then when I disconnect from astManager, but nothing is displayed until AFTER the loop finishes and it disconnects. Even my "debug" text does not display until after.

I need to get realtime (or continuous) events so I can parse them and not miss any.

How do I get my script to loop continuously/indefinitely and display the events as they occur?

NOTE: I put script in /var/www/html/ for testing purposes so I can access from my local network over VPN (it is NOT web accessible).

<?php
    $BASE_PATH="/var/lib/asterisk/agi-bin/";
    require $BASE_PATH."phpagi.php";
    $astManager = new AGI_AsteriskManager();
    $res = $astManager->connect($ast_host, $ast_user, $ast_pass);
    if(!$res) {
        syslog(LOG_INFO, "Connection to Asterisk manager failed.");
        //echo 'Connection to Asterisk manager failed.';
        die(100);
    }
echo 'debug 1';
    $astManager->add_event_handler('*','evt_all');
    $start_time = date('His');
    $end_time = $start_time + 5; //in seconds
    for ($x=$start_time; $x<$end_time; $x=date('His')) { } //LOOP until time runs out
echo 'debug 2';
    // Now we close the connection and logout
    $astManager->disconnect();
//FUNCTION - Do something with all events
function evt_all($ecode, $data, $server, $port) {
    echo '<br>'.$ecode.' - '.print_r($data,1);
}
?>

The trick is to loop but not sleep since while sleeping you ain't receiving anything.
Just do the following

while(true){
    $ami->wait_response(true);
}
