Basic PHP Installation & Setup

Using Composer (recommended)

Add rollbar/rollbar to your composer.json:

{
    "require": {
        "rollbar/rollbar": "^1"
    }
}

Manual installation if you are not using composer.json for your project

Keep in mind, that even if you're not using composer for your project (using composer.json), you will still need composer package to install rollbar-php dependencies.

  1. If you don't have composer yet, follow these instructions to get the package: install composer. It will be needed to install dependencies.
  2. Clone git repository rollbar/rollbar-php into a your external libraries path: git clone https://github.com/rollbar/rollbar-php
  3. Install rollbar-php dependencies: cd rollbar-php && composer install && cd ..
  4. Require rollbar-php in your PHP scripts: require_once YOUR_LIBS_PATH . '/rollbar-php/vendor/autoload.php';

Setup

Add the following code at your application's entry point:

<?php
use \Rollbar\Rollbar;

$config = array(
    // required
    'access_token' => 'POST_SERVER_ITEM_ACCESS_TOKEN',
    // optional - environment name. any string will do.
    'environment' => 'production',
    // optional - path to directory your code is in. used for linking stack traces.
    'root' => '/Users/brian/www/myapp'
);
Rollbar::init($config);    

Be sure to replace POST_SERVER_ITEM_ACCESS_TOKEN with your project's post_server_item access token, which you can find in the Rollbar.com interface.

This will install an exception handler (with set_exception_handler) and an error handler (with set_error_handler). If you'd rather not do that:

<?php
$set_exception_handler = false;
$set_error_handler = false;
Rollbar::init($config, $set_exception_handler, $set_error_handler);    

Send an Error and a Message

<?php
 use \Rollbar\Rollbar;
 use \Rollbar\Payload\Level;
    
// installs global error and exception handlers
Rollbar::init(
    array(
        'access_token' => ROLLBAR_TEST_TOKEN,
        'environment' => 'production'
    )
);
    
try {
    throw new \Exception('test exception');
} catch (\Exception $e) {
    Rollbar::log(Level::ERROR, $e);
}

// Message at level 'info'
Rollbar::log(Level::INFO, 'testing info level');

// With extra data (3rd arg) and custom payload options (4th arg)
Rollbar::log(
    Level::INFO,
    'testing extra data',
    array("some_key" => "some value") // key-value additional data
);
        
// If you want to check if logging with Rollbar was successful
$response = Rollbar::log(Level::INFO, 'testing wasSuccessful()');
if (!$response->wasSuccessful()) {
    throw new \Exception('logging with Rollbar failed');
}

// raises an E_NOTICE which will *not* be reported by the error handler
$foo = $bar;

// will be reported by the exception handler
throw new \Exception('testing exception handler');
