The package provides an ability to record performance profiles.

Requirements

• PHP 8.0 or higher.

Installation

The package could be installed with Composer:

composer require --dev yiisoft/profiler

If you use this package with Yii Config and there will be no @runtime alias in yiisoft/aliases configuration defined, application will throw "Invalid path alias" error.

To solve it, add the @runtime alias to the yiisoft/aliases configuration in params.php:

return [
 //...
 'yiisoft/aliases' => [
 'aliases' => [
 //...
 '@runtime' => '@root/runtime'
 ],
 ],
 //...
];

General usage

Profiling

use Psr\Log\NullLogger;
use Yiisoft\Profiler\Profiler;
use Yiisoft\Profiler\Target\LogTarget;

$logger = new NullLogger();
$target = new LogTarget($logger);

$profiler = new Profiler($logger, [$target]);

$profiler->begin('test');
//...some code
$profiler->end('test');

Nested profiling

$profiler->begin('test');
//...some code
 $profiler->begin('test');
 //...some code
 $profiler->end('test');
//...some code
$profiler->end('test');

Getting profiler messages

$messages = $profiler->getMessages(); 
print_r($messages);

Output

Array
(
 [0] => Yiisoft\Profiler\Message Object
 (
 [level:Yiisoft\Profiler\Message:private] => application
 [token:Yiisoft\Profiler\Message:private] => test
 [context:Yiisoft\Profiler\Message:private] => Array
 (
 [token] => test
 [category] => application
 [nestedLevel] => 0
 [time] => 1614703708.4328
 [beginTime] => 1614703708.4328
 [beginMemory] => 7696440
 [endTime] => 1614703708.4331
 [endMemory] => 7702392
 [duration] => 0.0003058910369873
 [memoryDiff] => 5952
 )

 )

)

Find profiler messages with a given token

$profiler->begin('test');
//...some code
$profiler->end('test');
$profiler->begin('another test');
//...some code
$profiler->end('another test');

$messages = $profiler->findMessages('another test');
print_r($messages);

Output

Array
(
 [0] => Yiisoft\Profiler\Message Object
 (
 [level:Yiisoft\Profiler\Message:private] => application
 [token:Yiisoft\Profiler\Message:private] => another test
 [context:Yiisoft\Profiler\Message:private] => Array
 (
 [token] => another test
 [category] => application
 [nestedLevel] => 0
 [time] => 1614703716.4328
 [beginTime] => 1614703716.4328
 [beginMemory] => 7696440
 [endTime] => 1614703716.4331
 [endMemory] => 7702392
 [duration] => 0.0003058910369873
 [memoryDiff] => 5952
 )

 )

)

$profiler = getProfiler();
// send profiler messages to targets
