What this developer tool does
It escapes all user code first, tokenizes common PHP syntax classes, and produces a readable display or declaration outline.
HTML escape → token classification → optional line numbering → long-line analysis → safe output rendering.
Syntax coloring is approximate and is not a complete PHP grammar implementation. The source is never executed.
Example
Input: a PHP function.
Output: escaped, numbered code with keyword, variable, string, and comment classes represented safely.
Tips for better output
- Use plain mode for copying.
- Use outline mode to navigate large files.
- Check long lines before code review.
