Younger brother, I got my website and want to use it myself. Can you take a look?

I got my website and want to use it myself... Let's take a look at it. I went to my website a few days ago and wanted to change it to my desired website and then publish it to the Internet. This php website needs to be installed. I 'd like to ask, will this cause infringement and I will install him? will he get the installation information? is this security guaranteed? Then, how should I modify the website so that I can use it myself... Can you take a look?
I posted a website a few days ago. I want to change it to my desired website and then publish it to the Internet. This php website needs to be installed. I want to ask if this will cause infringement, then I installed him. will he get the installation information? is this security guaranteed? How can I modify it to cancel the installation? I am a newbie, please kindly advise, (* ^__ ^ *) to share:
------ Solution --------------------
His source code may not steal your information if it is not encrypted. But use other people's stuff unless you carefully analyze the source code. The question of infringement depends on how he declares it. No website is secure. besides, you still use other people's products.
------ Solution --------------------
Learn how to use it and see if he has any instructions. if you don't say it, you can use it.
------ Solution --------------------
Under normal circumstances, you will not say that you are infringing. if you do not threaten his interests, or do not do bad things in his name. In addition, all the php websites you can use are open-source. You know about open source.
