Here are some open-source exchanges[1][2][3][4] (only the last one uses PHP). There is no guarantee that these projects don't have any bugs/backdoors. Unless you're a Senior developer and have a lot of experience, you probably shouldn't use them for anything other than learning purposes.

[1] https://github.com/rubykube/peatio (Active development).
[2] https://github.com/3s3s/opentrade
[3] https://github.com/blinktrade/bitex
[4] https://github.com/GMX9/Crypto-Exchange-PHP (Using Changenow.io API).

the bitex one, i dont know how to make a json website or python, can you tell me how. thanks

Learn JSON and Python. You can research over the internet and you will find many courses to learn any of programming language.
There is no magical word and after that, you will know to use these languages.
note: You can't be an owner of the crypto exchange using the free script and without any programming skill, except you have enough money to pay developers to maintain it all.
