I have one doubt :
I don't want to create web app for my ico project.I want to create android and Ios app for my project.
want to use PHP as a backend.
can anyone suggest me some development approach.I don't have any idea about how to achieve it.
Note : Smart contract Development done !

Unity, android sdk and nethereum dll's

Want to make backend in phP

Your backend is your smart contract

might be you don't get point :
on click of button ( in android) we call the php api and php api call the function from smart contract and update and get tge data abd return the dara

Well php is for web development, you dont want to create web app.. but android/ios app.. so use tools that are provided such as nethereum dlls to get functions to communicate with ethereum network...

Than it as not a dapp but a centralized service

Okay !

Suggest me any idea !

How to make android and ios app for upcoming ico

I am not getting how to achieve ot.

I already did

How ??

Please do not do an ico if you want answers for these things

Build ui in unity, add c# script which uses the nethereum .dll's and handle your onclicks etc

Or use web3 and cordova or something

Why you laughing josh ?

We are doing here any comedy show !

Don't laught atleast .
Because we all are on same page .
No one expert in this field and trying to get expertise in blockchai. development

So give your suggestion !
Don't laugh.it hurts and down our moral.

But want to do build mobile app.
I am taking it as a challenge

Error increase your exp. And your exp. decrease the errors.😉😉

If you are doing an ico you should know what you are talking about. Otherwise you an asshole for taking people's money

First of all..i am not doing any live project .
I am working on dummy sceneario.

So i can explore more !!

I already buid an demo and ico also.

I am clear in web !

But confuse about the mobile

That'a why i discuss with you expert guys !

Send us the smart contract so we can review?

Best way to learn

Sure ! If you want to do I am giving you my contract

Scenerio of sale is something like that :

will issue 100,000,000 DEV Tokens

Eighty percent (80%) of those tokens will be blocked and never move
Twenty percent (20%) or twenty million Tokens will be circulating and that will never change
( fifteen percent (15%) of dev Tokens to the public, 1% in airdrop or 4% team bounty)

Private Sale (2.5 Million DEV)
1 DEV = 0.001 ETH (2,500 ETH)
ICO Phase 1 (2.5 Million DEV)
1 DEV = 0.002 ETH (5,000 ETH)
ICO Phase 2 (5 Million DEV)
1 DEV = 0.003 ETH (15,000 ETH)
ICO Phase 3 (5 Million DEV)
1 DEV = 0.004 ETH (20,000 ETH)

Soft Cap: 7,500 ETH
Hard Cap: 42,500 ETH

Note : This is not refundable sale.

Josh @pablocryptobar010
Hope.. you help me alot.

Josh , Thanks for your words ! I understand what you want to say..
I will do home work on it.

@pablocryptobar010 , Yes programming is imporve from discussion.

Josh , just dummy secenario.

not relate to real world!
I am python developer and trying my best to learn solidity

Firstly I start with zeppelian solidity

But after that I felt its not good development appraoch so I start with ERC20 interface.

I do daily practise ! But no one is to me guide ..

Thanks man !Anything else you find intresting please share on community

Will check it later today

Enjoying the sunshine

sure !!

Thanks man!
Here is evening.

so no sunshine

do verify your contract before the ico or after the ico is good approach or not ???

is it mean you want to create "native" app, and not cordova app? then use react native 👍 no need for php backend, directly hit ethereum via infura

Thanks man!! For your cool response.
I know about the react native.
React native is use for cross platform!!!

But scenario is something like that :
make api in php
and call them from the app.

first question : 1. Does it possible ?
2. If no then movie is finish here bit if yes then
what will be the development approach ?
2.1 : What lib. I need to use.

if you insist to have backend, i recommend to use nodejs and not php. run web3 directly in nodejs

Yes I know in php vs node. Node is clear winner.
But what about If i opt PHP.

I am not talking for any project secanario .
It's just my curiosity.

check ethereum json rpc api, call them using php's curl

Have you done @pablocryptobar010 ?

You still have problem with your constructor you should look at that again.

Defining constructors as functions with the same name as the contract is deprecated. Use "constructor(...) { ... }" instead.

Either way you spelt constructor wrong, so its callable by anyone.
