Shu bot kodi tarqatamizmi?

Hozirgi payta telegramda botlarga qiziqish so'ngan. Bilmadim nimaga endi telegram botlar hech kimga kerakmas deb tuyilyapti. dastur chilar kupayganiga telegram bot yozuvchilar kupaydi. Hozirga paytda python nisbatan php bot kodlari judda kup o'ta mukammal hisobga olmasak judda kup botlar kodlari tarqalgan. Tarqatishga kod qolmagan menimcha. Php kanallar toxtab qolgan.
Hamma fikr #camentda kuta man negativ kerakmas 🤧

ancha vaqt buldi a 😁
Oqishlar bilan kod tashlash esda yuq.
Anonim chatlasha oladigan mukammal bot kodi tarqataymi?
Kim da qanday taklif bor?
