Raygun4PHP

Raygun.com provider for PHP 7.1+

Installation

Firstly, ensure that curl is installed and enabled in your server's php.ini file.

With Composer

Composer is a package management tool for PHP which automatically fetches dependencies and also supports autoloading - this is a low-impact way to get Raygun4PHP into your site.

If you use a *nix environment, follow the instructions to install Composer. Windows users can run this installer to automatically add it to the Path.
Inside your project's root directory create a composer.json file, containing:

{
        "require": {
            "mindscape/raygun4php": "^1.0"
        }
}

From your shell run php composer.phar install (*nix) or composer install (Windows). This will download Raygun4Php and create the appropriate autoload data.
Then in a PHP file just add:

require_once 'vendor/autoload.php';

and the library will be imported ready for use.

Usage

You can send both PHP errors and object-oriented exceptions to Raygun. An easy way to accomplish this is to create a file containing exception and error handlers which make calls to the appropriate Raygun4PHP functions. As above, import Raygun4PHP - if you're using Composer, just add require_once 'vendor/autoload.php', or if not manually import RaygunClient.php.

Then, create handlers that look something like this:

namespace
{
	// paste your 'requires' statement

	$client = new \Raygun4php\RaygunClient("apikey for your application");

	function error_handler($errno, $errstr, $errfile, $errline ) {
		global $client;
  		$client->SendError($errno, $errstr, $errfile, $errline);
	}

	function exception_handler($exception)
	{
		global $client;
		$client->SendException($exception);
    }

    function fatal_error()
    {
        global $client;
        $last_error = error_get_last();

        if (!is_null($last_error)) {
          $errno = $last_error['type'];
          $errstr = $last_error['message'];
          $errfile = $last_error['file'];
          $errline = $last_error['line'];
          $client->SendError($errno, $errstr, $errfile, $errline);
        }
    }

    set_exception_handler('exception_handler');
    set_error_handler("error_handler");
    register_shutdown_function("fatal_error");
}

Note that if you are placing in inside a file with a namespace of your choosing, the above code should be declared to be within the global namespace (thus the namespace { } is required). You will also need whichever requires statement as above (autoload or manual) before the $client instantiation.

Copy your application's API key from the Raygun.io dashboard, and place it in the constructor call as above (do not include the curly brackets).

If the handlers reside in their own file, just import it in every file where you'd like exceptions and errors to be sent, and they will be delivered to Raygun.io.

Configuration

Sending method - async/sync

Raygun4PHP has two algorithms which it can use to send your errors:

Asynchronous: POSTs the message and returns to your script immediately without waiting for the response from the Raygun API.
Synchronous: POSTs the message, blocks and receives the HTTP response from the Raygun API. This uses a socket connection which is still reasonably fast. This also allows the use of the debug mode to receive the HTTP response code; see below.

This can be set by passing in a boolean as the 2nd parameter to the constructor:

$client = new \Raygun4php\RaygunClient("apiKey", $useAsyncSending);

$useAsyncSending options

Type: boolean

Linux/OS X default: true

Windows default: false

If $useAsyncSending is true, and the script is running on a *nix platform, the message will be delivered asynchronously. SendError() and SendException() will return 0 if all went well.
If $useAsyncSending is false, the script will block and receive the HTTP response.

false is the only effective option on Windows due to platform and library limitations within the supported versions.

Proxies

A HTTP proxy can be set if your environment can't connect out through PHP or the curl binrary natively:

$client = new \Raygun4php\RaygunClient("apiKey");
$client->setProxy('http://someproxy:8080');

Debug mode

The client offers a debug mode in which the HTTP response code can be returned after a POST attempt. This can be useful when adding Raygun to your site. This is accessed by passing in true as the third parameter in the client constructor:

$client = new \Raygun4php\RaygunClient("apiKey", $useAsyncSending, $debugMode);

$debugMode options

Default: false

If true is passed in, and $useAsyncSending is set to false, client->SendException() or SendError() will return the HTTP status code of the POST attempt.

Note: If $useAsyncSending is true, $debugMode is not available.

Response codes

202: Message received by Raygun API correctly
403: Invalid API key. Copy it from your Raygun Application Settings, it should be of the form new RaygunClient("A+nUc2dLh27vbh8abls7==")

Version numbers

You can transmit the version number of your PHP project along with the message by calling SetVersion() on your RaygunClient after it is instantiated - this is optional but recommended as the version number is considered to be first-class data for a message.

Adding Tags

Tags can be added to error data to provide extra information and to help filtering errors within Raygun. They are provided as an array of strings or numbers passed as the 5th argument to the SendError function and as the 2nd argument to the SendException function.

The declaration of the exception and error handlers using tags could look something like this:

$tags = array("testing-enviroment", "machine-4");

function error_handler($errno, $errstr, $errfile, $errline) {
	global $client, $tags;
  	$client->SendError($errno, $errstr, $errfile, $errline, $tags);
}

function exception_handler($exception) {
	global $client, $tags;
	$client->SendException($exception, $tags);
}

function fatal_error()
{
  global $client;
  $last_error = error_get_last();

  if (!is_null($last_error)) {
    $errno = $last_error['type'];
    $errstr = $last_error['message'];
    $errfile = $last_error['file'];
    $errline = $last_error['line'];
    $client->SendError($errno, $errstr, $errfile, $errline, $tags);
  }
}

Affected user tracking

New in 1.5: additional data support

You can call $client->SetUser, passing in some or all of the following data, which will be used to provide an affected user count and reports:

SetUser($user = null, $firstName = null, $fullName = null, $email = null, $isAnonymous = null, $uuid = null)

$user should be a unique identifier which is used to identify your users. If you set this to their email address, be sure to also set the $email parameter too.

This feature and values are optional if you wish to disable it for privacy concerns. To do so, pass true in as the third parameter to the RaygunClient constructor.

Note that this data is stored as cookies. If you do not call SetUser the default is to store a random UUID to represent the user.

This feature can be used in CLI mode by calling SetUser() at the start of your session.

Custom error grouping

Control of how error instances are grouped together can achieved by passing a callback to the SetGroupingKey method on the client. If the callback returns a string, ideally 100 characters or less, errors matching that key will grouped together. Overriding the default automatic grouping. If the callback returns a non-string value then that error will be grouped automatically.

$client = new \Raygun4php\RaygunClient("apiKey");
$client->SetGroupingKey(function($payload, $stackTrace) {
  // Inspect the above parameters and return a hash from the properties

  return $payload->Details->Error->Message; // Naive message-based grouping only
});

Filtering Sensitive Data

Some error data will be too sensitive to transmit to an external service, such as credit card details or passwords. Since this data is very application specific, Raygun doesn't filter out anything by default. You can configure to either replace or otherwise transform specific values based on their keys. These transformations apply to form data ($_POST), custom user data, HTTP headers, and environment data ($_SERVER). It does not filter the URL or its $_GET parameters, or custom message strings. Since Raygun doesn't log method arguments in stack traces, those don't need filtering. All key comparisons are case insensitive.

$client = new \Raygun4php\RaygunClient("apiKey");
$client->setFilterParams(array(
	'password' => true,
	'creditcardnumber' => true,
	'ccv' => true,
	'php_auth_pw' => true, // filters basic auth from $_SERVER
));
// Example input: array('Username' => 'myuser','Password' => 'secret')
// Example output: array('Username' => 'myuser','Password' => '[filtered]')

You can also define keys as regular expressions:

$client = new \Raygun4php\RaygunClient("apiKey");
$client->setFilterParams(array(
	'/^credit/i' => true,
));
// Example input: array('CreditCardNumber' => '4111111111111111','CreditCardCcv' => '123')
// Example output: array('CreditCardNumber' => '[filtered]','CreditCardCcv' => '[filtered]')

In case you want to retain some hints on the data rather than removing it completely, you can also apply custom transformations through PHP's anonymous functions. The following example truncates all keys starting with "address".

$client = new \Raygun4php\RaygunClient("apiKey");
$client->setFilterParams(array(
	'Email' => function($key, $val) {return substr($val, 0, 5) . '...';}
));
// Example input: array('Email' => 'test@test.com')
// Example output: array('Email' => 'test@...')

Note that when any filters are defined, the Raygun error will no longer contain the raw HTTP data, since there's no effective way to filter it.

Updating Cookie options

Cookies are used for the user tracking functionality of the Raygun4Php provider. In version 1.8 of the provider, the options passed to the setcookie method can now be customized to your needs.

$client = new \Raygun4php\RaygunClient("apiKey");
$client->SetCookieOptions(array(
    'expire'   => 2592000, // 30 * 24 * 60 * 60
    'path'     => '/',
    'domain'   => '',
    'secure'   => false,
    'httponly' => false
));

Troubleshooting

As above, enable debug mode by instantiating the client with

$client = new \Raygun4php\RaygunClient("apiKey", FALSE, TRUE);

This will echo the HTTP response code. Check the list above, and create an issue or contact us if you continue to have problems.

400 from command-line Posix environments

If, when running a PHP script from the command line on *nix operating systems, you receive a '400 Bad Request' error (when debug mode is enabled), check to see if you have any LESS_TERMCAP environment variables set. These are not compatible with the current version of Raygun4PHP. As a workaround, unset these variables before your script runs, then reset them afterwards.

Error Control Operators (@)

If you are using the setup as described above errors will be send to Raygun regardless of any lines prepended with an error control operator (the @ symbol). To stop these errors from being sent to Raygun you can call PHP's error_reporting method which return 0 if the triggered error was preceded by an @ symbol.

Error handler example:

function error_handler($errno, $errstr, $errfile, $errline ) {
    global $client;
    if(error_reporting() !== 0) {
        $client->SendError($errno, $errstr, $errfile, $errline);
    }
}
