[MySQL][PHP] Wyciąganie dowolnego fragmentu danych z pola "data" Opcje

[tromarek1]

Nie wiem jak dokładnie opisać swój problem. Dodaję nową funkcjonalność do kalendarza, ale nigdy się nie spotkałem z takim sposobem zapisu danych. Otóż mam Tabelę o nazwie dopbsp_days.
Wewnątrz niej unique_id, calendar_id, day, year, data, price_min, price_max.

Rekordy wewnątrz data prezentują się mniej-więcej w następujący sposób:

Dla mnie szok, że te dane nie są w oddzielnych kolumnach. Nigdy się z czymś takim nie spotkałem. Żaden z poradników, który czytałem nie wspominał nawet, że tak można. Ale do sedna.
Chciałbym móc edytować te dane za pomocą kodu PHP(powiedzmy, że chciałbym np. zmienić o godzinie 15:00 dostępność[available] na wartość "0", status na "booked" i zmienić ["available":20] na ["available":19]).


Poprosił bym również ewentualnie( lub "i") link do poradnika szczegółowo tłumaczącego jak operować na takich danych.

Byłbym naprawdę wdzieczny. Uczę się, więc proszę o wyrozumiałość
