README

Provides Zend\Db adapters with extensions for database query profiling, as well as a profiler similar to ZF1's Zend_Db_Profiler. I ported much of this code from ZF1's Zend_Db.

Note: this module now works with Zend\Db's built-in profiler.

Note: PHP >= 5.3.6 is required for stack traces with query profiles.

Composer/Packagist Users

Please note the name of this project's package has changed to bjyoungblood/bjy-profiler in order to match composer/packagist's new naming conventions. Please update your composer.json to use the new package name.

Configuration & Usage

Following is a sample database configuration:

<?php

$dbParams = array(
 'database' => 'changeme',
 'username' => 'changeme',
 'password' => 'changeme',
 'hostname' => 'localhost',
 // buffer_results - only for mysqli buffered queries, skip for others
 'options' => array('buffer_results' => true)
);

return array(
 'service_manager' => array(
 'factories' => array(
 'Zend\Db\Adapter\Adapter' => function ($sm) use ($dbParams) {
 $adapter = new BjyProfiler\Db\Adapter\ProfilingAdapter(array(
 'driver' => 'pdo',
 'dsn' => 'mysql:dbname='.$dbParams['database'].';host='.$dbParams['hostname'],
 'database' => $dbParams['database'],
 'username' => $dbParams['username'],
 'password' => $dbParams['password'],
 'hostname' => $dbParams['hostname'],
 ));

 if (php_sapi_name() == 'cli') {
 $logger = new Zend\Log\Logger();
 // write queries profiling info to stdout in CLI mode
 $writer = new Zend\Log\Writer\Stream('php://output');
 $logger->addWriter($writer, Zend\Log\Logger::DEBUG);
 $adapter->setProfiler(new BjyProfiler\Db\Profiler\LoggingProfiler($logger));
 } else {
 $adapter->setProfiler(new BjyProfiler\Db\Profiler\Profiler());
 }
 if (isset($dbParams['options']) && is_array($dbParams['options'])) {
 $options = $dbParams['options'];
 } else {
 $options = array();
 }
 $adapter->injectProfilingStatementPrototype($options);
 return $adapter;
 },
 ),
 ),
);

After you've run a couple queries (or before, if you so choose), you can use the service locator to grab the adapter using whatever alias you provide (using Zend\Db\Adapter\Adapter is a good way to simply replace Zend\Db's adapter with my profiling adapter.

$profiler = $sl->get('Zend\Db\Adapter\Adapter')->getProfiler();
$queryProfiles = $profiler->getQueryProfiles();
