Who Uses This PHP Beautifier?

Development Teams

  • Enforce consistent style across Laravel, Symfony, or WordPress projects

return match(\$x){1=>\$a,2=>\$b,default=>throw new \\\\Exception};
return match (\$x) {\n    1 => \$a,\n    2 => \$b,\n    default => throw new \\\\Exception\n};

❓ Frequently Asked Questions

Does this tool support PHP 8.2 features like readonly and attributes?

Yes! Full support for PHP 8.0–8.2, including attributes, readonly classes, constructor promotion, match expressions, and arrow functions.

🔒Is my code sent to your servers?

Absolutely not. All formatting happens entirely in your browser using Prettier's standalone version. Your code never leaves your machine.

🧮Why does 2.50 stay 2.50 instead of becoming 2.5?

We preserve significant decimal places in float literals (like prices) to maintain developer intent. You can configure this in the options.

🚫Why remove the closing ?> tag?

PSR-12 and modern frameworks (Laravel, Symfony) recommend omitting it to prevent accidental whitespace output that can break HTTP headers.

How fast is the formatting?

Instantly. The tool loads once, then formats any code in <100ms. No lag, no server round-trips.

Pro Tips

Best Practice

Use 'floatPrecision: 2' for e-commerce, APIs, and financial apps to preserve prices like 19.99.

Best Practice

Combine with a Git pre-commit hook to auto-format code before every push.

Best Practice

Use the formatter to teach junior devs: paste messy code and show the cleaned version side-by-side.

Best Practice

Never commit code with trailing commas in PHP <7.2 — our tool disables them automatically.
