PHP Code Viewer is a quick-look tool for PHP classes, functions, and scripts. It re-indents your code with balanced braces and renders it with syntax highlighting.

• Re-indent copy-pasted code from logs.
• Share readable code with teammates.
• Audit generated PHP output.
• Teach PHP syntax with clean examples.

Features

• Brace-aware re-indentation
• PHP syntax highlighting
• PHP parsed locally in your browser
• Respects HEREDOC / NOWDOC
• Fast copy-paste

How to use PHP Code Viewer

1. Paste PHP. Drop any PHP source.
2. Click Run. See it re-indented and highlighted.
3. Copy. Paste into your doc or IDE.

Example (before/after)
