Yet Another Biorhythm Calculator PHP

✨ Key Features

• 📅 Date-based Calculation: User enters DOB + target date → script outputs cycles.
• 📈 Classic 3 Cycles: Physical (23-day), Emotional (28-day), Intellectual (33-day).
• ➕ Optional Extra Cycles: Intuitive / Creativity / Aesthetic (easy to enable in code).
• 🖼 Graph / Table Output: Show as percentages, as a simple chart, or as color-coded “critical day”.
• 🌐 Embeddable: Add to any PHP page (e.g. biorhythm.php) or inside an existing CMS template.
• 🛠 Easy to Translate: Labels, month names, and descriptions are plain strings → quick multilingual sites.
• 🧪 Clean Logic: Cycle formulae use standard sinus approach, so results are consistent across calculators.

⚙️ Technical Stack

• Language: PHP 7.x/8.x (no heavy frameworks required)
• Frontend: HTML5, minimal CSS, optional inline JS for nicer graphing
• Server: Any Apache/Nginx shared hosting that runs PHP
• Data: No database required (pure calculation)

Expert tip: if you want nicer charts, plug the output into a lightweight JS chart library (Chart.js, ApexCharts) — just echo the PHP results as JSON.
