PHP Code Formatter & Beautifier
Format and beautify your PHP code instantly using industry-standard style presets. Paste messy or inconsistently formatted PHP and get clean output that matches PSR-12, Laravel, or WordPress Coding Standards — with full control over indentation, brace placement, and line length.
如何使用
Paste your PHP code into the input area. Select a style preset to auto-configure formatting options, or manually adjust indent width, brace style, and line length. The formatted code updates instantly in the output panel — copy it with one click.
特征
- 样式预设 – One-click formatting with PSR-12 (PHP standard), Laravel, and WordPress Coding Standards configurations.
- PHP-Specific Brace Rules – PSR-12 uses next-line braces for classes and methods but same-line for control structures. WordPress uses same-line everywhere. Each preset applies the correct convention automatically.
- Array Formatting – Handles both short array syntax (
[]) and traditionalarray()syntax with proper indentation. - 可配置缩进 – Choose between 2 spaces, 4 spaces, or tabs. WordPress defaults to tabs; PSR-12 and Laravel default to 4 spaces.
- Control Structure Spacing – Enforces proper spacing after keywords like
if,for,foreach,while， 和switch. - 空行规范化 – Consistent spacing between methods, properties, and class sections.
- 实时格式化 – 在您键入或更改任何选项时，输出会即时更新。
何时使用此工具
Use this tool when cleaning up PHP code for pull requests, converting between style guides when moving code between frameworks, or standardizing formatting across a project. It’s especially useful for reformatting WordPress plugin code to match WordPress standards, or converting older PHP code to PSR-12 compliance.
常问问题
-
What is PSR-12 and why does it matter for PHP?
PSR-12 is the Extended Coding Style Guide published by the PHP-FIG (Framework Interoperability Group). It defines rules for code formatting including indentation, brace placement, line length, and spacing. PSR-12 matters because it provides a universal standard — code from different frameworks and libraries all looks consistent when following PSR-12, reducing cognitive load during code review and collaboration.
-
What is the difference between PSR-12 and WordPress Coding Standards?
The biggest differences are indentation and brace placement. PSR-12 uses 4-space indentation and places opening braces on the next line for classes and methods (but same line for control structures). WordPress uses tabs for indentation and places opening braces on the same line for everything. WordPress also has unique rules like Yoda conditions (comparing constants first) and specific array formatting preferences.
-
Should PHP code use spaces or tabs?
PSR-12 requires 4 spaces per indent level — this is the standard for most modern PHP frameworks including Laravel and Symfony. WordPress Coding Standards require tabs. The PHP community is split, but PSR-12 with spaces is more widely adopted in new projects. The key is consistency within a project: never mix tabs and spaces in the same codebase.
-
What is PHP-CS-Fixer and how does it compare to manual formatting?
PHP-CS-Fixer is a command-line tool that automatically fixes PHP code to follow coding standards like PSR-12 or custom rule sets. Unlike manual formatting, it uses a proper PHP parser to understand code structure, handling edge cases like heredocs, complex expressions, and multi-line arguments correctly. It can be integrated into CI pipelines and editor plugins for automatic formatting on save.
