When testing my plugin, Simple Ajax Chat (SAC), I use the following script to save time testing various chat functionality.

Note that this script is for SAC version 20160408 and better. For older versions, change simple-ajax-chat-core.php to simple-ajax-chat.php on line 23.

$sac_host = $sac_request = $sac_referer = $sac_address = '';
if (isset($_SERVER["HTTP_HOST"]))    $sac_host    = htmlentities($_SERVER["HTTP_HOST"],    ENT_QUOTES, 'UTF-8');
if (isset($_SERVER["REQUEST_URI"]))  $sac_request = htmlentities($_SERVER["REQUEST_URI"],  ENT_QUOTES, 'UTF-8');
if (isset($_SERVER['HTTP_REFERER'])) $sac_referer = htmlentities($_SERVER['HTTP_REFERER'], ENT_QUOTES, 'UTF-8');
if (isset($_SERVER['REMOTE_ADDR']))  $sac_address = htmlentities($_SERVER['REMOTE_ADDR'],  ENT_QUOTES, 'UTF-8');

$sac_chat_url = 'http://' . $sac_host . $sac_request;
$sac_match = preg_match("/$sac_host/i", $sac_referer);

if ($sac_referer == 'http://example.com/chat/') {
	$test_email_message = 
		'Host: ' . $sac_host . "\n" .
		'Request: ' . $sac_request . "\n" . 
		'Referrer: ' . $sac_referer . "\n" . 
		'IP Address:  ' . $sac_address . "\n" .  
		'Matched: ' . $sac_match . "\n" . 
		'Verify: ' . strip_tags($_POST['sac_verify']) . "\n" .
		'Check: ';
	
	// log or mail..
}

$sac_email = preg_match("/simple-ajax-chat-core.php/i", $sac_request);
			
if ($sac_email) {
	if ((isset($sac_match)) && ($sac_match !== null) && ($sac_match !== 0) && ($sac_match !== '')) {
		$match = 'pass';
	} else {
		$match = 'fail';	
	}
	if (empty($_POST['sac_verify'])) {
		$postVerify = 'pass';
	} else {
		$postVerify = 'fail';	
	}
	if ((isset($sac_referer)) && ($sac_referer !== null) && ($sac_referer !== '')) {
		$refPass = 'pass';
	} else {
		$refPass = 'fail';	
	}
	if (current_user_can('read')) {
		$loggedinuser = 'true';
	} else {
		$loggedinuser = 'false';
	}
	$test_email_message = 
		'Host: ' . $sac_host . "\n" .
		'Request: ' . $sac_request . "\n" . 
		'Referrer: ' . $sac_referer . "\n" . 
		'IP Address:  ' . $sac_address . "\n" .  
		'Matched: ' . $match . "\n" . 
		'Verify: ' . $postVerify . "\n" .
		'Check: ' . $refPass . "\n" . 
		'LoggedIn: ' . $loggedinuser . "\n" . 
		'COOKIE: ' . strip_tags($_COOKIE['PHPSESSID']) . "\n" . 
		'SESSION: ' . strip_tags(session_id());
	
	// log or mail..
}

It’s quick and dirty, but sufficient for on-the-fly testing of chat messages.
