does anyone know how can someone create wallets of any currency using PHP ?

Are you planning to make a website that can generate wallet and priv keys in php?
I think you can't get any free script here mostly they are selling it look at this thread as sample https://bitcointalk.org/index.php?topic=2276372.0
But if you wanted to make your own you should install your own bitcoin core you make wallet in php via JSON-RPC
You can check the JSON-RPC in php here https://en.bitcoin.it/wiki/API_reference_(JSON-RPC)

But if you wanted an easy step without running bitcoind daemon you should buy the script from trusted sellers.. i don't know if the above link is trusted or not since its neutral i think its still safe..

@BitMaxz: thanks, but as mentioned in the OP, I am not looking to make it for BTC, but other alt-coins that do not currently have a paperwallet generator, so having a ton of daemons, might be pointless after all.

I wonder, considering it is basic cryptography, can someone shed some light, which php functions shall be utilized to generate a valid wallet & priv key combo randomly and how it can be customized to work for each different crypto coin and it's settings ?

Find out how to manually generate a key for each of the currency you want, then just implement it in PHP?

Where's the issue exactly?

so, nobody knows ?

Are you attempting to wrap a native coin client in PHP or code it from scratch in PHP? The difference is immense.

not a PHP expert, but this topic comes up all time in StackExchange. You might search there, basically people use libraries that are required.
Closest I could come up with is here:
https://bitcoin.stackexchange.com/questions/64117/php-is-there-a-way-to-convert-a-private-ecdsa-key-to-its-corresponding-public-k

Simply do a search in the topline with the word "php", and you'll get some replies. Hope this brings you forward.
