<?php PHP Formatter

How to Use the Online PHP Formatter

Writing PHP is often fast-paced, leading to messy indentation and unreadable code blocks. This tool is a robust "Beautifier" designed to parse your messy PHP code and reassemble it with industry-standard formatting rules (PSR-12 inspired) directly in your browser.

Step-by-Step Instructions

• Paste Code: Copy your raw, minified, or messy PHP code into the left "Input Code" panel.
• Configure Settings: Use the toolbar to select your preferred indentation style (standard is 4 spaces) and brace style.
  • Collapse (K&R): Opening braces on the same line.
  • Expand (Allman): Opening braces on a new line.
• Format: Click the "Format PHP" button. The tool runs a client-side lexical analysis to restructure your code.
• Copy: Use the "Copy" button in the output header to grab your clean code.

Technical Logic & Accuracy

Unlike simple regex-based replacers, this tool uses a Token-Based Approach. It first "protects" sensitive content like strings (`"..."`, `'...'`) and comments (`//`, `/* */`) by replacing them with unique placeholders. It then analyzes the structural tokens of your code (braces, semicolons, keywords) to apply formatting. Finally, it restores the protected content. This ensures that a semicolon inside a string (e.g., `echo "Error: Code 5;";`) doesn't accidentally trigger a new line.

Why Format PHP?

Consistent formatting is crucial for debugging and collaboration.

• Readability: Proper indentation visualizes the hierarchy of your loops and conditional statements instantly.
• Error Detection: Missing braces or unclosed statements become obvious when code is strictly aligned.
• Standards Compliance: Following PSR standards makes your code look professional and maintainable by other developers.
