What is PHP Formatter?

PHP Formatter is a free online tool that formats, beautifies, and pretty-prints PHP code with proper indentation, line breaks, and spacing. PHP formatting is essential for developers who work with minified, compressed, or poorly formatted scripts. Clean, readable PHP code improves maintainability, debugging, and team collaboration.

How PHP Formatter Works

Step 1: Paste your PHP code into the input area.

Step 2: Select formatting options like indent size (2 or 4 spaces).

Step 3: Click the Format button to beautify the code.

Step 4: Copy the formatted output.

The parser tokenizes PHP keywords, variables, functions, and control structures, then applies consistent indentation and line breaks.

Before and After Examples

Before (Ugly/Minified): if($user=="admin"){echo"Welcome admin";}else{echo"Access denied";}

After (Formatted): if ($user == "admin") { echo "Welcome admin"; } else { echo "Access denied"; }

Before: function add($a,$b){return$a+$b;}

After: function add($a, $b) { return $a + $b; }

PHP Formatting Best Practices

Indentation: Use 4 spaces per indent level for consistency.

Brace Placement: Place opening braces on the same line for control structures.

Spacing: Add spaces after commas, around operators, and before/after control structures.

Line Length: Keep lines under 80-120 characters for readability.

Comments: Use // for single line, /* */ for multi-line comments.

PSR Standards for PHP

PSR-1: Basic Coding Standard - Files should use tags, side effects should be avoided.

PSR-12: Extended Coding Style - Specific rules for braces, spaces, indentation, and line length.

Following PSR standards ensures compatibility with PHP frameworks and tools like PHP_CodeSniffer.

Common PHP Formatting Fixes

Missing Semicolons: The formatter adds missing semicolons at line endings.

Inconsistent Indentation: Corrects mixed spaces and tabs to consistent indentation.

Array Formatting: Formats PHP arrays with proper indentation for multi-line arrays.

Control Structures: Formats if, else, foreach, while, and for loops properly.

Function Calls: Adds spaces after commas in function parameters.

PHP 8 Features Support

Attributes: Supports #[Attribute] syntax formatting.

Named Arguments: Formats function calls with named parameters.

Match Expressions: Properly formats match statements with arrow syntax.

Constructor Property Promotion: Formats compact class definitions.

Union Types: Preserves type declaration formatting.

IDE Integration Tips

Many code editors have built-in PHP formatters: VS Code (PHP Intelephense), PhpStorm (Code Style settings), Sublime Text (phpfmt package).

For command line, use php-cs-fixer or phpcbf to format PHP files automatically.

This online tool is perfect for quick formatting when you don't have access to an IDE.

Conclusion

PHP Formatter is an essential tool for PHP developers. It transforms messy, unreadable PHP code into clean, professionally formatted code that is easy to read, debug, and maintain. Use this tool for all your PHP formatting needs.
