Code Style Check

Analyze PHP code for style consistency and PSR-12 compliance.

Detection Patterns

1. PSR-12 Violations

// BAD: Opening brace on same line for class
class User {
}

// GOOD: Opening brace on new line
class User
{
}

// BAD: Opening brace on new line for methods
public function getName()
{
}

// GOOD: Opening brace on same line for control structures
if ($condition) {
}

// BAD: No space after keywords
if($condition) {}
foreach($items as $item) {}

// GOOD: Space after keywords
if ($condition) {}
foreach ($items as $item) {}

2. Line Length

// BAD: Exceeds 120 characters
$result = $this->veryLongServiceName->processWithManyParameters($parameter1, $parameter2, $parameter3, $parameter4, $parameter5);

// GOOD: Broken into multiple lines
$result = $this->veryLongServiceName->processWithManyParameters(
    $parameter1,
    $parameter2,
    $parameter3,
    $parameter4,
    $parameter5
);

3. Indentation

// BAD: Mixed tabs and spaces
class User
{
	private string $name;  // Tab
    private int $age;      // Spaces
}

// GOOD: Consistent 4 spaces
class User
{
    private string $name;
    private int $age;
}

4. Blank Lines

// BAD: No blank line after namespace
namespace App\Service;
use App\Repository;

// GOOD: Blank line after namespace
namespace App\Service;

use App\Repository;

// BAD: No blank line between methods
public function getName(): string
{
    return $this->name;
}
public function setName(string $name): void
{
    $this->name = $name;
}

// GOOD: Blank line between methods
public function getName(): string
{
    return $this->name;
}

public function setName(string $name): void
{
    $this->name = $name;
}

5. Trailing Whitespace

// BAD: Trailing spaces at end of line
$name = 'John';
$age = 25;

// GOOD: No trailing whitespace
$name = 'John';
$age = 25;

6. Use Statement Ordering

// BAD: Unordered use statements
use App\Service\OrderService;
use App\Entity\User;
use Symfony\Component\HttpFoundation\Request;
use App\Repository\UserRepository;

// GOOD: Grouped and alphabetized
use App\Entity\User;
use App\Repository\UserRepository;
use App\Service\OrderService;
use Symfony\Component\HttpFoundation\Request;
