Fun with PHP functions
summary
Covers concrete PHP curiosities and practical surprises: levenshtein distance and soundex/metaphone behavior with examples, date_sun_info returns sunrise times and easter_date use, Julian day conversions and the French Republican calendar, string ROT13 and chop as rtrim alias, plus a concrete count of 448 timezone identifiers in PHP. Demos rely on standard PHP functions and source-code inspection; useful when wanting exact behavior, edge cases, or quick code snippets rather than high-level platitudes.
