Spiral Framework 3.0 doesn't have any out of the box tools for dumping variables.
But you can use third-party packages like symfony/var-dumper to view the content of your variables and instances.
If you want to dump the contents of your variables to the RoadRunner error log, you need to create a function, like in the example below:
<?php
declare(strict_types=1);
use Symfony\Component\VarDumper\Caster\ReflectionCaster;
use Symfony\Component\VarDumper\Cloner\VarCloner;
use Symfony\Component\VarDumper\Dumper\CliDumper;
use Symfony\Component\VarDumper\VarDumper;
if (!\function_exists('dumprr')) {
/**
* Dump value int STDERR.
*/
function dumprr(mixed $value): mixed
{
if (!\defined('STDERR')) {
\define('STDERR', \fopen('php://stderr', 'wb'));
}
static $dumper = new CliDumper(STDERR);
//
// Output modifiers
//
$cloner = new VarCloner();
// remove File and Line definitions from a custom closure dump
$cloner->addCasters(ReflectionCaster::UNSET_CLOSURE_FILE_INFO);
// Set new handler and store previous one
$prevent = VarDumper::setHandler(static fn ($value) => $dumper->dump($cloner->cloneVar($value)));
$result = VarDumper::dump($value);
// Reset handler
VarDumper::setHandler($prevent);
return $result;
}
}
The package is included into
spiral/app, and there's also a helper functiondumprr.
