Issue Description
Hint: Paste any code and click Format to beautify indentation, spacing, and structure instantly.
How It Works
- Step 1: Paste PHP code with formatting issues—inconsistent indentation, missing spaces around operators, or non-PSR-compliant brace placement.
- Step 2: The formatter tokenizes PHP using lexical analysis, identifying keywords, operators, variables, and string literals while preserving code logic.
- Step 3: Applies PSR-12 rules including 4-space indentation, opening braces on same line for methods, spaces after control structure keywords (if, for, while), and proper namespace declarations.
- Step 4: Returns formatted PHP code that passes PHP_CodeSniffer checks, ready for Laravel, Symfony, or WordPress projects with consistent team coding standards.
PHP Formatting Examples
Example: PSR-12 Formatting
<?php
class UserController{
public function store($request){
$user=new User();
$user->name=$request->name;
if($user->save()){
return response()->json(['success'=>true]);
}else{
return response()->json(['error'=>'Failed']);
}
}
}<?php
class UserController
{
public function store($request)
{
$user = new User();
$user->name = $request->name;
if ($user->save()) {
return response()->json(['success' => true]);
} else {
return response()->json(['error' => 'Failed']);
}
}
}Key Changes:
The formatter applies PSR-12 standards: opening braces for classes on new lines, method braces on new lines, 4-space indentation throughout. Spaces are added around operators ($user = new User() instead of $user=new User()). Control structures (if/else) gain spaces after keywords and around parentheses. Array elements get spaces after => operators for readability. The blank line after namespace/use statements and between logical blocks improves visual separation. This formatting ensures compatibility with PHP_CodeSniffer, PHP-CS-Fixer, and modern IDE expectations, making code reviews faster and merge conflicts less frequent in team environments.
Frequently Asked Questions
Can I switch between PSR-1, PSR-2, and PSR-12 formatting styles?
The formatter applies PSR-12 (the current standard) by default. PSR-2 is deprecated, and PSR-1 is incorporated into PSR-12. Custom configurations (2-space indent, alternate brace styles) require manual adjustment post-formatting. The tool prioritizes modern PSR compliance over legacy preferences.
Is my PHP code processed on external servers?
No. All tokenization and reformatting run client-side via JavaScript-based PHP parsers. Your PHP source code—whether proprietary business logic, confidential API implementations, or internal frameworks—never leaves your browser. Zero network transmission occurs during formatting.
What PHP syntax features are unsupported or problematic?
The formatter handles PHP 5.6 through PHP 8.3 syntax. Heredoc/nowdoc strings with complex interpolation may format unpredictably. Files mixing PHP with large HTML blocks outside <?php tags may have formatting issues. Files exceeding 5MB hit browser memory limits—split large frameworks or trim comments before formatting.
