Excimer: A low-overhead sampling profiler for PHP — UI Client

Getting started

Install the PHP extension:

pecl install excimer

Install the server.

Activate the profiler in your app. This package provides a single class which does not depend on the Composer autoloader. So you can use it from a file configured with auto_prepend_file in php.ini.

require './vendor/wikimedia/excimer-ui-client/src/ExcimerClient.php';
\Wikimedia\ExcimerUI\Client\ExcimerClient::setup( [
    'url' => 'https://localhost/excimer/index.php',
] );

Show a link to the profile in an appropriate place in your app:

use Wikimedia\ExcimerUI\Client\ExcimerClient;
if ( ExcimerClient::isActive() ) {
    echo ExcimerClient::singleton()->makeLink();
}
